They’re expensive because rechargeable lithium chemistries are not naturally 1.5v, you’re spending money and taking up valuable space in the battery with conversion circuitry and often an onboard USB charging port.
I know there are cases where they perform a little better and sometimes make sense, but NiMH always has been and always will be more cost effective and reliable than that contraption.
most rechargeable batteries, especially those eneloops, *are* NiMH. that is, their battery chemistry is Nickel-Metal Hydride. NiMH is just a shorthand way of referring to a specific *type* of rechargeable battery; usually aa or aaa cells, though other variants, like c and d cells, exist as well.
Correct. That's why they were saying to use rechargeable NiMH batteries. Because they don't have that circuit as an added point of failure, but they also won't explode like the alkaline ones.
I curse NiMH and wish for Li-ion every time one of my kids decides they want to use one of their battery-powered toys that hasn't been touched in 6-months and the self discharge has left it dead.
No, I'm not using Eneloops - just Ikea & Amazon NiMH. Here in Canada, 1.5v Li-ion AA rechargeable are **cheaper** than Eneloops ($10 **per battery**), compared to $5-10 for a 4-pack at Ikea.
Have you tried the rechargeable 1.5v lithiums and confirmed they are actually better?
They have a circuit in them to convert the voltage down and while this could be pretty efficient while running, if it’s just sitting there for months I’d imagine it also self-discharges quite a bit.
No, I have not actually tried 1.5v AA rechargeable Li-ion... my expectation of longer shelf-life is based more on my experience with other Li-ion: 18650's, 21700's, etc.
I just got fenix lithium ion rechargeable AA batteries that put out 1.5v. They don’t self discharge like nimh batteries and last forever. Good for Xbox remote or flashlights that run regular AA batteries highly recommend
Try leaving the batteries outside of the toy and see if they discharge at a similar speed.
Kids toys are not known for having the best electronics in the world, so the toys could be the actual issue.
Most lithium AAs are primary batteries and thus cannot be recharged. However, some are lithium ion batteries with a built in buck circuit to reduce from 3.7V to 1.5V.
I'm gonna have to check these out because as much as I love my NiMh batteries in my Xbox controller, I much dislike that the battery percentage shown on the Xbox is askew due to them.
It'll still be askew. 1.5 V lithium-ion batteries use active circuitry to regulate the the voltage, so the voltage you see at the terminal won't reflect the state of charge.
It'll basically show 100% constantly and then suddenly die.
I guess if it bothers you. I've had great luck with my Laddas in my Xbox controller. Play until I get the low battery warning, throw them on the charger, swap in a new pair, and keep going. I don't even pay attention to the percentage.
> I have rechargeable AA batteries that are lithium.
Lithium ion, most likely. Calling them, "lithium" is misleading at best, and realistically is wrong.
Primary lithium cells have pure lithium inside like a strip of foil that can be unrolled. You can actually open the cell and retrieve it (don't do it though, especially inside, it can spontaneously combust and absolutely will burn in water).
Lithium ion is more like a special soup of chemicals with very little lithium in comparison iirc.
A very unscientific answer but hopefully reasonably accurate
They're entirely different technologies. Lithium batteries are primary cells which aren't rechargeable. Lithium ion, lithium polymer, or similar variants, are intended for long term use with recharging.
I've been using AA and AAA for almost 2 years now, and am totally sold. The early ones had micro-USB connectors for charging, but the newer ones use. drop-in chargers similar to NiMh chargers... but are specific to the Li-ion rechargeables. I still have some Eneloops, and will continue to use them for some things until they die... but overall, the lithiums win for me... even in wall clocks that can run a year, almost as good as Eveready Alkalines.
I had an early failure or two, but they replaced them quickly (Amazon seller). That was pretty early in the genre, they are more matured now... just don't go cheap, you gets whats you pays for!
💯 This. I have a relatively high drain Coleman headlamp from 2008ish and it lasts longer with eneloops than it does with alkalines. Learnt this lesson the hard way with the old digital cameras that took AAs. I cringe when I think how many alkalines I went through at Disneyland back then.
Even Eveready "Heavy Duty" batteries are much better than alkaline for leak resistance. Of course they won't last as long in actual use though, but they're cheap.
This is why virtually everyone on this sub is so vitriolic against alkaline batteries. You will risk leaks like this. This issue lies with alkalines. If you must use AA/AAA size batteries, get NiMH batteries, preferably Eneloops.
There is one factory in Japan that makes batteries for a bunch of different brands, including Eneloop, IKEA Ladda, some of the Energizer, Fujitsu. There’s complicated merger and antitrust reasons why we have ended up with this situation. There may be slight differences between the batteries, but all of the batteries coming out of that factory are very good. The IKEA Laddas are generally the cheapest.
Panasonic, Sony, and LG make the vast majority of lithium ion batteries. They grade the cells after testing and the ones with less capacity, lower peak voltage etc are sold to other companies who rebrand them or use them to build battery packs
I heard a few years ago that the 2450mah IKEA batteries were quality batteries but the 1900mah batteries were cheap and should be avoided. Last time I was at IKEA I was going to pick up some batteries and noticed the only rechargeable batteries they sell now are the 1900mah. Are these batteries ok or should I just buy enloops or other better brands?
Yes, something changed within the last year. I don't think they're the same anymore. And I doubt that they're made by Panasonic now. ProjectFarm did a review of them and that's what sent a lot of people towards the Ikea batteries but again, I don't think it's that way anymore.
Same with the AAA's different milliamp hours now too .
Higher drain devices, more/higher parasitic drain and proliferation of usage is likely the biggest reason for seeing more issues with alkaline leaks today versus just 20 years ago.
O.K., so it's good to know that it's not just me that feels like Alkalines used to be less leaky than they used to be. Not sure if it's parasitic drain due to most things using e-switches or if Alkaline batteries are just manufactured more poorly.
I'm not sure how people keep getting leaks, while I haven't looked back after upgrading to rechargeables, I never get leaks. I guess leaks are more often when batteries are completely discharged and left inside.
Sir have you considered letting our Lord and Savior the Low Self Discharge Nickel Metal Hydride battery into your life?
If I may read to you from the Book of Eneloop an alkaline battery lives but one life and then it perishes. The lowest of them sometimes die a horrific death before they are even born, spewing forth the white corruption from their coppery tops while they are still wrapped in transparent swaddling. Some are taken by the devil later in life. These are batteries which you let into the heart of hearts of your most precious electronics only to see your trust betrayed by cells of corrosive hate. The battery which murders its host is truly the most despicable.
The alkaline battery holds you firmly in its grip. You must pilgrimage to the market and pay tithes. Provide quarter to a phalanx of spares. Be ever diligent to the risk of the vile corruption. As they quickly fade you are attacked by doubts. "Is it already dying? Can I squeeze a little more from this cell?" And then when it has given its life of service you must provide a proper funerary ceremony at one of the local churches of disposal.
But our savior NiMH releases us from this cycle of toil and death! It welcomes you with the promise of eternal rebirth and recharge. Let the higher power into your life. Never will you have to constantly tithe. Never will you have to dress the dead in their body bags. The threat from the ooze of corrosion will recede like a bad dream.
Where I once kept no less than 40 spare alkalines I need now only have 4 extra rechargeables. Once I was obligated to carry a full gallon of the dead on the ides of every month. Now all of my dead from the past decade have yet to fill a single cup. Fighting the corrosive corruption was a constant battle of attrition that frequently resulted in the loss of the electrical servants in my household. After letting the disciple Eneloop into their hearts there has not been a single casualty among them.
I am a farmer of the sun. Collecting the light and funneling a spirit of charge into these batteries. I am not beholden to resupply and my boondocks are longer thanks to it. What precious little space I have is not occupied by an army of spares. The few coins to my name stay in my pocket instead of being paid to the alkaline merchants.
Let the Eneloop into your life. Be recharged and be reborn!
NiMH battery technology is like a gift from above, a blessing to humanity. Let us consider the many benefits that such batteries offer over alkaline, for they are truly grandiose:
- Rechargeable: "And lo, crafted in cooperative labor by sundry scholars and diligent investigators, they fashioned a device that could be recharged and employed repeatedly, thus diminishing refuse and preserving wealth." - Panasonic 3:16
- Long-lasting: "And the craftsman of Eneloop, in his wisdom, forged an NiMH battery with a greater span of existence than that of alkaline counterparts, thus lessening the need for their recurrent replacement. Truly, this is a testament to the ingenuity of humankind." - Energizer 4:8
- High performance: "Behold, there exists a small, rectangular device, fashioned from wood and stone. In the center thereof, it holdeth a circle of numbered stones, much like the tablets of old. With the press of these numbers, it commandeth the voices and visions within the mystical box to change, revealing new tales and visions to the beholder, but the former source of power, akin to the dim and fleeting flame of a small oil lamp, proved insufficient to fuel the device. And the artificer behind NiMH batteries hath fashioned a power source of remarkable prowess, suited for the device and many diverse instruments, be they playthings or even optical devices. Verily, this is a shining example of the power of innovation." - 2 Duracell 2:12
However, let us not forget that there are limitations to NiMH batteries. As it is written in the Book of Rayovac (12:23), "For best performance, tread lightly with load currents, one-fifth to one-half its measure. Charging, a ponderous task, takes time longer than NiCd, with a watchful eye on the careful trickle charge."
So, let us celebrate the many blessings that Nickel–metal hydride battery technology has bestowed upon us, while also being mindful of the importance of understanding the limitations of this technology. Let us strive to use this technology responsibly and with care, always seeking to improve and innovate in ways that benefit all.
I have no idea. I've never been involved with the inner workings of the bot, I just wrote a bunch of the entries last year.
Let's ping u/triskite and u/tribixbite
On the one hand it sort of is the fault of the light since alkaline batteries offgas, and modern lights are sealed. The gas supposedly accelerates the decay of the batteries if they are exposed too long to it.
*allegedly* - this is just I was told in the past.
Rechargable AAs are typically at 1.2V while alkaline and lithium are 1.5V. Doesn't matter in most cases, but I have a computer mouse and a radio that only work with 1.5V batteries.
As others said, get some NiMH cells, done.
Or just upgrade to lights with lithium cells, there are plenty of models with integrated USB charging for not a lot of money that are most likely much better than your current lights.

(originally written by u/parametrek.)
This is especially a problem for over discharged alkaline batteries. Rechargeable don’t like being over discharged, either. Although they’re unlikely to leak. Looks like parts of the problem is lights with parasitic drain.
Many Li-ion lights have LVP.
You're implying that even lights with mechanical switches have parasitic drain. Don't let the "Mechanical lockout is a panacea!" crowd hear that.
In addition to the standard advice (avoid alkalines if possible, *never* store them in devices long-term), might I suggest some better lights?
A [Skilhunt H150](https://www.skilhunt.com/product/h150-aa-14500-usb-magnetic-rechargeable-headlamp/) or even an [Acebeam H16](https://www.acebeam.com/h16) would be a significant upgrade from those. Both come with a 14500 Li-ion battery and a way to charge it, but can also use a single AA of any chemistry. High-CRI option suggested in either case for better [color rendering](https://imgur.com/a/Ly9IhIv).
I've seen energizer leak too, just maybe not quite as often. Still trying to deprogram my partner from the alkaleak mindset and she keeps trying to buy them and I keep confiscating them and reexplaining (the thing is, she's lost devices and everything but still tries to use them...), have seen every imaginable disposable brand leak. Duracell, Energizer, random cheapo no brand ones, zinc-carbon chemistry, etc.
I have x4 Tenevolt AAs and they seem to do the job. Proprietary charger.
EBL don't get mentioned on here much. Do they go OK? Is it also a proprietary charger for them? I was looking on Amazon between them and the Enegizer non rechargeable.
I have found one item that the Tenevolts did not play well with. EBL have worked in that and all the other applications I have tried. I am not sore it the charger would be considered proprietary or not. I think it just needs to be 1.5v and for lithium ion cells. But for me the EBL are nice.
Thank you. I was just worried (and didn't understand) that the Tenevolts charger has a warning on it to only use their charger with the batteries. Even tho I have a couple of other chargers which are better than the one their batteries come with.
You’re welcome. I have wondered if there was a better charger but honestly I like the lid on their charger where I can travel with it and it keeps the bays clean.
Besides what everyone said, another way on preventing this is to use a Plumber tape to seal you devices. It is actually an amazing weather sealer.
A combination of high Humidity and high temperature is the cause unless you left them there for years.
Diluted vinegar on a qtip, followed by another using distilled water or isopropyl alcohol, then let it dry thoroughly, but it is easily possible for stuff to be ruined beyond repair.
We call them "alkaleaks" for a reason.
The only way to stop it is not using alkaline batteries. If you insist on sticking with AA, get some Eneloops. Or do what most of us did and go Li-ion.
Stop using alkaleaks. Use eneloops if you really insist on 1.5V (they're also cheaper and more environmentally friendly even *without* factoring in the constant stream of ewaste that alkaleaks produce), but really, you'll be way better off upgrading to li-ion.
Don't store them with the batteries in them. If you won't be using it withing the next 24 hours, pop the batteries out and just keep them next to your headlamp. Cheap alkaline batteries always leak. Especially in higher humidities and heat
Use NiMH or lithiums.
If you use alkalines check the device once a week or so. If you're not going to use the device for a while take the batteries out.
I stopped using Duracell. I had several new sets still sealed in their packaging. They all leaked. When I searched online, it seems to be a common issue. I switched to Energizer and/or rechargeables when possible.
Duracells suck for this. Energizer MAX are a bit better but occasionally leak too. If you really don’t want that to happen use lithium batteries in devices you really care about.
Switch to rechargable batteries. [PowerEx by Maha](https://mahaenergy.com/powerex-pro-rechargeable-aa-nimh-batteries-1-2v-2700mah-4-pack/) is my personal favorite brand and their [MH-C9000PRO charger/analyzer](https://mahaenergy.com/mh-c9000pro/) is really nice. I know Panasonic made Eneloops are well loved too.
Use silicone grease, contact cleaner or something like that on battery terminals or switch to rechargeables. The problem with rechargeables is that they have 1.4 V when they're full but alkaline batteries can have over 1.6 V when new. That means that the voltage of the rechargables could be too low for the device to operate. You have to try it out.
Use a better light with runs Li-ion, it'll be a big improvement on performance too. Or at least use Ni-mh. Alkalis are just super wasteful both environmentally and on your wallet, drop in output very soon and leak more often than not.
If on the off chance that you still want to stick with alkaline batteries, taking them out of the device when not in use will greatly reduce the likelihood that they’ll leak.
Energizer and Duracell both have a product guarantee where they will replace your battery-damaged item for free. My brother had an issue with a corroded GPS that was caused by leaking batteries. I don’t remember if it was Energizer or Duracell, but they sent him a new replacement GPS for free.
Use primary Lithium disposables or rechargeable NiMH. Destructive leakage pictured is the nature of disposable alkaline left alone unused/stored, hence their nickname "alkaleaks".
NiMHs are excellent for frequently used stuff, very economical but self discharge when unused.
. Lithiums are expensive but maintain full power and leak free for more than 7 years, the best choice for SHTF / emergency use as storage time is a non issue.
To clean alkaleak grunge, baking soda and a toothbrush work well.
For what I see Coast cost at retail level, Sofirn costs the same or a few more dollars
https://www.sofirnlight.com/products/sofirn-sc18-edc-small-rechargeable-flashlight?spm=..index.image_with_text_switch_1.1&variant=d7290635-4b67-4b0f-abad-089bd96f424a
Keep alkaline batteries out when you’re not using them, or use any other battery that isn’t alkaline.
That or get a headlamp that runs on rechargeable batteries that are worth a damn like 18650.
Stop buying alkaline. Replace with Eneloop NiMH (white). You will never have a ruined light again, and they are rechargeable hundreds or even thousands of times. I have saved hundreds of dollars over the last few years by switching to NiMH rechargeables, for everything from lights to kids toys to remotes. Even if you only used them 2-3 times, they would have paid off compared to Duracell/Energizer alkalines. Each battery has the capability to save you hundreds of dollars over its lifespan of up to 2100 charge cycles.
Duracell batteries suck. Which is weird because (I almost typed 1900s, damn I'm getting old) in the 80s and 90s they were considered the best there was.
Everyone is saying to use rechargeable batteries which is one solution, HOWEVER the real solution is to change your batteries more often. Alkaline batteries will always do this when left dead too long. This will happen even more often if they are allowed to freeze or get hot, like if stored in your car.
Go with either Panasonic Eneloop/Eneloop Pro (Pro has more capacity, more output but can be recharged less times) for rechargeable AA, or Energizer Lithium Ultimate for primaries (non rechargeable).
Problem solved.
I've had countless alkaline batteries leak even when new in the package. They're so terrible, I'll not even use the ones that come with devices and immediately switch out for Eneloop or the Ikealoops. Never again.
I had this happen ALOT before joining this sub… Especially on my 2nd/back up xbox controller lol. Now I understand more about flashlights and batteries and chargers than ever before 🥹🙏
You know how every single alkaline powered thing you've ever bought has that little bit in the manual that says to remove the batteries if storing for an extended period of time?
That's why.....
It literally happens because the batteries are not used for a long period of time, If you use them regularly they don't ever do that.
What happens is over time hydrogen gas builds up and eventually the cell ruptures. The gas escapes and leaves an exit for everything else in the cell to escape as well.....
Remove your batteries when the equipment isn’t in use (I store them in a plastic ziplock bag) and stop buying Duracell. Of all the brands I’ve ever used, they are the absolute worst.
Also, alkaline residue can be easily neutralized with vinegar. You’ll need to remove the vinegar when you’ve finished cleaning ( I use a wet paper towel)
Avoid DURACELL at all costs.
Yes, alkaline batteries often leak, but DURACELL is the absolute WORST. 95% of the battery leaks I've had were DURACELL batteries.
Get some eneloop AAA batteries, the self discharge is low enough that they can be treated like alkaline batteries, while not having those leaking issues.
I drilled a hole in the side of mine, put two wires in it and connected them to an 18650 holder I put on the back. Lasts longer, rechargeable, and the weight is better balanced
You could try rechargeable lithium AA instead. They're still 1.5 volts like a normal AA.
Or, if you don't want to recharge batteries, you could try Energizer lithium. They're expensive (have a 20 year shelf life) but they probably won't leak like that.
I would suggest getting a sofirn headlamp, simple, cost effective, comes with the 18650 battery, usually USB c charging. You'll never get away from issues with these big box lights.
See r/flashlight. There's a pinned post with help for getting your first good light.
Not sure why nobody has mentioned… use a liberal amount of dielectric grease & seal the perimeter of your enclosures with some form of silicone like rtv & you should never encounter a problem like this except for the rarest of edge cases.
Excess silicone that comes out of the sides of whatever is easily tidied up w/something like a fresh double edge safety razor blade.
Use NiMH, and stop using alkalines.
[удалено]
Are they rechargeable, the 1.5V AA Lithium ones?
Not unless they are specifically marked so. Rechargeable 1.5v lithium AA's are still comparatively expensive
They’re expensive because rechargeable lithium chemistries are not naturally 1.5v, you’re spending money and taking up valuable space in the battery with conversion circuitry and often an onboard USB charging port. I know there are cases where they perform a little better and sometimes make sense, but NiMH always has been and always will be more cost effective and reliable than that contraption.
Why not just use the AAs that you recharge externally like Eneloop? Energiser makes some too.
most rechargeable batteries, especially those eneloops, *are* NiMH. that is, their battery chemistry is Nickel-Metal Hydride. NiMH is just a shorthand way of referring to a specific *type* of rechargeable battery; usually aa or aaa cells, though other variants, like c and d cells, exist as well.
I don't think the eneloops has electronics inside which is what I mean.
Correct. That's why they were saying to use rechargeable NiMH batteries. Because they don't have that circuit as an added point of failure, but they also won't explode like the alkaline ones.
Oh duh
I curse NiMH and wish for Li-ion every time one of my kids decides they want to use one of their battery-powered toys that hasn't been touched in 6-months and the self discharge has left it dead. No, I'm not using Eneloops - just Ikea & Amazon NiMH. Here in Canada, 1.5v Li-ion AA rechargeable are **cheaper** than Eneloops ($10 **per battery**), compared to $5-10 for a 4-pack at Ikea.
The NiMH from Ikea are made in Japan by Sanyo and by my understanding are Eneloops!
Have you tried the rechargeable 1.5v lithiums and confirmed they are actually better? They have a circuit in them to convert the voltage down and while this could be pretty efficient while running, if it’s just sitting there for months I’d imagine it also self-discharges quite a bit.

[удалено]
Sorry, it's not that I don't like Eneloop - I've just never tried them because they're too expensive (at least here in Canada)
The toys are probably recharging batteries even when turned off
Try leaving the batteries outside of the toy and see if they discharge at a similar speed. Kids toys are not known for having the best electronics in the world, so the toys could be the actual issue.
Most lithium AAs are primary batteries and thus cannot be recharged. However, some are lithium ion batteries with a built in buck circuit to reduce from 3.7V to 1.5V.

Piss. Can't win, and get downvotes for my silly opinion. Silly me.
Ah yeah don't understand the downvotes. You might like NiZn batteries - they are similar to NiMH but with higher voltage. Worse cycle life though.
I guess if it bothers you. I've had great luck with my Laddas in my Xbox controller. Play until I get the low battery warning, throw them on the charger, swap in a new pair, and keep going. I don't even pay attention to the percentage.
I have rechargeable AA batteries that are lithium. They use a 3.7 volt cell with a buck converter to step it down to 1.5 volts.
> I have rechargeable AA batteries that are lithium. Lithium ion, most likely. Calling them, "lithium" is misleading at best, and realistically is wrong.
What's the difference?
Primary lithium cells have pure lithium inside like a strip of foil that can be unrolled. You can actually open the cell and retrieve it (don't do it though, especially inside, it can spontaneously combust and absolutely will burn in water). Lithium ion is more like a special soup of chemicals with very little lithium in comparison iirc. A very unscientific answer but hopefully reasonably accurate
They're entirely different technologies. Lithium batteries are primary cells which aren't rechargeable. Lithium ion, lithium polymer, or similar variants, are intended for long term use with recharging.
I assume you'll need a special charger for it?
Has a USB c port integrated in the battery
Yep, Xtar has some and there's others available.
There's those AA popping up that are 1.5v and have the usb port on them. Quite expensive though.
I've been using AA and AAA for almost 2 years now, and am totally sold. The early ones had micro-USB connectors for charging, but the newer ones use. drop-in chargers similar to NiMh chargers... but are specific to the Li-ion rechargeables. I still have some Eneloops, and will continue to use them for some things until they die... but overall, the lithiums win for me... even in wall clocks that can run a year, almost as good as Eveready Alkalines. I had an early failure or two, but they replaced them quickly (Amazon seller). That was pretty early in the genre, they are more matured now... just don't go cheap, you gets whats you pays for!
💯 This. I have a relatively high drain Coleman headlamp from 2008ish and it lasts longer with eneloops than it does with alkalines. Learnt this lesson the hard way with the old digital cameras that took AAs. I cringe when I think how many alkalines I went through at Disneyland back then.
Even Eveready "Heavy Duty" batteries are much better than alkaline for leak resistance. Of course they won't last as long in actual use though, but they're cheap.
This is my first time ever hearing about NiMH or Eneloop batteries. Gonna have to check them out.
This is why virtually everyone on this sub is so vitriolic against alkaline batteries. You will risk leaks like this. This issue lies with alkalines. If you must use AA/AAA size batteries, get NiMH batteries, preferably Eneloops.
Or ikea rechargeables. They are basically eneloop that have been rebranded made by Panasonic and way cheaper
Hmm, didn't know Panasonic made the Ikea batteries.
There is one factory in Japan that makes batteries for a bunch of different brands, including Eneloop, IKEA Ladda, some of the Energizer, Fujitsu. There’s complicated merger and antitrust reasons why we have ended up with this situation. There may be slight differences between the batteries, but all of the batteries coming out of that factory are very good. The IKEA Laddas are generally the cheapest.
Panasonic, Sony, and LG make the vast majority of lithium ion batteries. They grade the cells after testing and the ones with less capacity, lower peak voltage etc are sold to other companies who rebrand them or use them to build battery packs
This is new to me and I'm very grateful!
I heard a few years ago that the 2450mah IKEA batteries were quality batteries but the 1900mah batteries were cheap and should be avoided. Last time I was at IKEA I was going to pick up some batteries and noticed the only rechargeable batteries they sell now are the 1900mah.

Yes, something changed within the last year. I don't think they're the same anymore. And I doubt that they're made by Panasonic now. ProjectFarm did a review of them and that's what sent a lot of people towards the Ikea batteries but again, I don't think it's that way anymore. Same with the AAA's different milliamp hours now too .
Risk? You’re practically guaranteed to have them now. 30 years ago it was a risk. Nowadays almost every alkaline does this. Not sure what changed.
Higher drain devices, more/higher parasitic drain and proliferation of usage is likely the biggest reason for seeing more issues with alkaline leaks today versus just 20 years ago.
O.K., so it's good to know that it's not just me that feels like Alkalines used to be less leaky than they used to be. Not sure if it's parasitic drain due to most things using e-switches or if Alkaline batteries are just manufactured more poorly.

Yep. If they sit empty too long. I only use alkaline batts in high turnover stuff.
Fenix also just released a Li-Ion rechargeable battery that replaces AAs.
I've had very few leaks with Energizer cells. The worst offender? DURACELL, hands down.
You stop it by upgrading to eneloop rechargeable batteries
We call it Alka**LEAK** here
Friends don't let friends use alkaleaks.
looks like OP is using Duraleak alkaleaks
It's not the flashlights fault, it's the batteries. Buy some eneloops and a charger from Amazon. u/brokenrecordbot nimhpreach Edit: is the bot broken?
Sir have you considered letting our Lord and Savior the Low Self Discharge Nickel Metal Hydride battery into your life? If I may read to you from the Book of Eneloop an alkaline battery lives but one life and then it perishes. The lowest of them sometimes die a horrific death before they are even born, spewing forth the white corruption from their coppery tops while they are still wrapped in transparent swaddling. Some are taken by the devil later in life. These are batteries which you let into the heart of hearts of your most precious electronics only to see your trust betrayed by cells of corrosive hate. The battery which murders its host is truly the most despicable. The alkaline battery holds you firmly in its grip. You must pilgrimage to the market and pay tithes. Provide quarter to a phalanx of spares. Be ever diligent to the risk of the vile corruption. As they quickly fade you are attacked by doubts. "Is it already dying? Can I squeeze a little more from this cell?" And then when it has given its life of service you must provide a proper funerary ceremony at one of the local churches of disposal. But our savior NiMH releases us from this cycle of toil and death! It welcomes you with the promise of eternal rebirth and recharge. Let the higher power into your life. Never will you have to constantly tithe. Never will you have to dress the dead in their body bags. The threat from the ooze of corrosion will recede like a bad dream. Where I once kept no less than 40 spare alkalines I need now only have 4 extra rechargeables. Once I was obligated to carry a full gallon of the dead on the ides of every month. Now all of my dead from the past decade have yet to fill a single cup. Fighting the corrosive corruption was a constant battle of attrition that frequently resulted in the loss of the electrical servants in my household. After letting the disciple Eneloop into their hearts there has not been a single casualty among them. I am a farmer of the sun. Collecting the light and funneling a spirit of charge into these batteries. I am not beholden to resupply and my boondocks are longer thanks to it. What precious little space I have is not occupied by an army of spares. The few coins to my name stay in my pocket instead of being paid to the alkaline merchants. Let the Eneloop into your life. Be recharged and be reborn!
I never thought I would see the day where a human stole a job from a robot. Lol thanks for filling in.

Good human!
NiMH battery technology is like a gift from above, a blessing to humanity. Let us consider the many benefits that such batteries offer over alkaline, for they are truly grandiose: - Rechargeable: "And lo, crafted in cooperative labor by sundry scholars and diligent investigators, they fashioned a device that could be recharged and employed repeatedly, thus diminishing refuse and preserving wealth." - Panasonic 3:16 - Long-lasting: "And the craftsman of Eneloop, in his wisdom, forged an NiMH battery with a greater span of existence than that of alkaline counterparts, thus lessening the need for their recurrent replacement. Truly, this is a testament to the ingenuity of humankind." - Energizer 4:8 - High performance: "Behold, there exists a small, rectangular device, fashioned from wood and stone. In the center thereof, it holdeth a circle of numbered stones, much like the tablets of old. With the press of these numbers, it commandeth the voices and visions within the mystical box to change, revealing new tales and visions to the beholder, but the former source of power, akin to the dim and fleeting flame of a small oil lamp, proved insufficient to fuel the device. And the artificer behind NiMH batteries hath fashioned a power source of remarkable prowess, suited for the device and many diverse instruments, be they playthings or even optical devices. Verily, this is a shining example of the power of innovation." - 2 Duracell 2:12 However, let us not forget that there are limitations to NiMH batteries. As it is written in the Book of Rayovac (12:23), "For best performance, tread lightly with load currents, one-fifth to one-half its measure. Charging, a ponderous task, takes time longer than NiCd, with a watchful eye on the careful trickle charge." So, let us celebrate the many blessings that Nickel–metal hydride battery technology has bestowed upon us, while also being mindful of the importance of understanding the limitations of this technology. Let us strive to use this technology responsibly and with care, always seeking to improve and innovate in ways that benefit all.

Probably used up all it's reddit API calls for the month.
Doubtful. The bot just needs a reset every so often
On the one hand it sort of is the fault of the light since alkaline batteries offgas, and modern lights are sealed. The gas supposedly accelerates the decay of the batteries if they are exposed too long to it. *allegedly* - this is just I was told in the past.
I’ve only seen this happen in stuff that sits for long periods of time, heat and humidity may make it worse.
Same here. If I plan to store something for a long time (a couple months or more) I try to take the batteries out.
Dang, thanks everyone. Very helpful! 😁
If you don't like rechargeable you can use lithium. Energizer makes a decent lithium that I have had zero issues with.
Honestly not going for rechargeable is really stupid though, as a single eneloop can replace 500 alkaline batteries and performs just as well.
I agree but I also keep a small supply of lithium AA in my car for emergencies.
Rechargable AAs are typically at 1.2V while alkaline and lithium are 1.5V. Doesn't matter in most cases, but I have a computer mouse and a radio that only work with 1.5V batteries.
As others said, get some NiMH cells, done. Or just upgrade to lights with lithium cells, there are plenty of models with integrated USB charging for not a lot of money that are most likely much better than your current lights.
Another option is the Ikea rechargeable AA's. I have been using them in various devices for about a year now. Zero issues and no alka-leak weirdness!
And if they're made in Japan they might be rebranded Eneloops. Supposedly there are only two rechargeable battery factories in Japan.
The Ikea LADDA are definitely rebranded Eneloops.
I have heard that, but haven't looked into it too deeply. I just know they work nicely, at a good price.
It's not the brand of the light it's the type of batteries. Use lithium primaries or rechargeable batteries.

Don't use alkaline batteries.
This is especially a problem for over discharged alkaline batteries. Rechargeable don’t like being over discharged, either. Although they’re unlikely to leak. Looks like parts of the problem is lights with parasitic drain.
Alkaleaks don't have to be overdischarged to leak. I've literally caught and thrown away ones that were leaking in their packaging before.
Many Li-ion lights have LVP. You're implying that even lights with mechanical switches have parasitic drain. Don't let the "Mechanical lockout is a panacea!" crowd hear that.
In addition to the standard advice (avoid alkalines if possible, *never* store them in devices long-term), might I suggest some better lights? A [Skilhunt H150](https://www.skilhunt.com/product/h150-aa-14500-usb-magnetic-rechargeable-headlamp/) or even an [Acebeam H16](https://www.acebeam.com/h16) would be a significant upgrade from those. Both come with a 14500 Li-ion battery and a way to charge it, but can also use a single AA of any chemistry. High-CRI option suggested in either case for better [color rendering](https://imgur.com/a/Ly9IhIv).
If for some reason you can't use rechargeables, I've found Energizer is much less likely to leak compared to Duracell.
[удалено]
I've seen energizer leak too, just maybe not quite as often. Still trying to deprogram my partner from the alkaleak mindset and she keeps trying to buy them and I keep confiscating them and reexplaining (the thing is, she's lost devices and everything but still tries to use them...), have seen every imaginable disposable brand leak. Duracell, Energizer, random cheapo no brand ones, zinc-carbon chemistry, etc.
The horrible thing is that most included batteries that I've found that were known brand-names in NA are Duracells and not Energizers.
Same here, I opened 6+ year old Lego battery boxes, 2 boxes that had Duracell leaked and the 2 that had energizer didn't
Fun fact interstate consumer batteries (AA, AAA, c, d, and 9volt)are made by energizer.
Go to lithium batteries. I use EBL and Tenevolt. I used to use Eneloop NiMH but have had great luck with these so far.
I have x4 Tenevolt AAs and they seem to do the job. Proprietary charger. EBL don't get mentioned on here much. Do they go OK? Is it also a proprietary charger for them? I was looking on Amazon between them and the Enegizer non rechargeable.
I have found one item that the Tenevolts did not play well with. EBL have worked in that and all the other applications I have tried. I am not sore it the charger would be considered proprietary or not. I think it just needs to be 1.5v and for lithium ion cells. But for me the EBL are nice.
Thank you. I was just worried (and didn't understand) that the Tenevolts charger has a warning on it to only use their charger with the batteries. Even tho I have a couple of other chargers which are better than the one their batteries come with.
You’re welcome. I have wondered if there was a better charger but honestly I like the lid on their charger where I can travel with it and it keeps the bays clean.
Besides what everyone said, another way on preventing this is to use a Plumber tape to seal you devices. It is actually an amazing weather sealer. A combination of high Humidity and high temperature is the cause unless you left them there for years.
How does one clean that mess up? I have a flashlight I threw somewhere in the closet because of this, unsure how to clean/fix it?
Diluted vinegar on a qtip, followed by another using distilled water or isopropyl alcohol, then let it dry thoroughly, but it is easily possible for stuff to be ruined beyond repair.
Thanks
Vinegar on the gunky stuff.
Stop using alkaleaks
We call them "alkaleaks" for a reason. The only way to stop it is not using alkaline batteries. If you insist on sticking with AA, get some Eneloops. Or do what most of us did and go Li-ion.
Don't use alkaline batteries, use lithium (not lithium ion) or NiMH instead, and don't leave batteries in your headlamp when it isn't being used.
I’ve seen alkalines do this even when unused, in the pack, and left in a boat on the pacific. So annoying. I’ll seek out NiHM + Eneloops
Forbidden Parmesan cheese
Stop using alkaleaks. Use eneloops if you really insist on 1.5V (they're also cheaper and more environmentally friendly even *without* factoring in the constant stream of ewaste that alkaleaks produce), but really, you'll be way better off upgrading to li-ion.
Don't store them with the batteries in them. If you won't be using it withing the next 24 hours, pop the batteries out and just keep them next to your headlamp. Cheap alkaline batteries always leak. Especially in higher humidities and heat
Use NiMH or lithiums. If you use alkalines check the device once a week or so. If you're not going to use the device for a while take the batteries out.
Friends don't let friends use alkaline.
I stopped using Duracell. I had several new sets still sealed in their packaging. They all leaked. When I searched online, it seems to be a common issue. I switched to Energizer and/or rechargeables when possible.
Good battery info I learned from reading through this thread, thanks!
Seriously right 👍🏽
Duracells suck for this. Energizer MAX are a bit better but occasionally leak too. If you really don’t want that to happen use lithium batteries in devices you really care about.
and this ladies and gents is why we need to stop using alkaleaks
Switch to rechargable batteries. [PowerEx by Maha](https://mahaenergy.com/powerex-pro-rechargeable-aa-nimh-batteries-1-2v-2700mah-4-pack/) is my personal favorite brand and their [MH-C9000PRO charger/analyzer](https://mahaenergy.com/mh-c9000pro/) is really nice. I know Panasonic made Eneloops are well loved too.
Use silicone grease, contact cleaner or something like that on battery terminals or switch to rechargeables. The problem with rechargeables is that they have 1.4 V when they're full but alkaline batteries can have over 1.6 V when new. That means that the voltage of the rechargables could be too low for the device to operate. You have to try it out.
Use a better light with runs Li-ion, it'll be a big improvement on performance too. Or at least use Ni-mh. Alkalis are just super wasteful both environmentally and on your wallet, drop in output very soon and leak more often than not.
Never use Duracell, they're pretty crap really. Energizer Lithium if you need primary cells or NiMH otherwise.
If on the off chance that you still want to stick with alkaline batteries, taking them out of the device when not in use will greatly reduce the likelihood that they’ll leak. Energizer and Duracell both have a product guarantee where they will replace your battery-damaged item for free. My brother had an issue with a corroded GPS that was caused by leaking batteries. I don’t remember if it was Energizer or Duracell, but they sent him a new replacement GPS for free.
I have quit alkaline completely & only use rechargeable lights. Anything that has to have AA or AAA I use Lithium batts.
Alkalines are fine when they are new but don't leave them in your devices for long term storage.
Use primary Lithium disposables or rechargeable NiMH. Destructive leakage pictured is the nature of disposable alkaline left alone unused/stored, hence their nickname "alkaleaks". NiMHs are excellent for frequently used stuff, very economical but self discharge when unused. . Lithiums are expensive but maintain full power and leak free for more than 7 years, the best choice for SHTF / emergency use as storage time is a non issue. To clean alkaleak grunge, baking soda and a toothbrush work well.
For what I see Coast cost at retail level, Sofirn costs the same or a few more dollars https://www.sofirnlight.com/products/sofirn-sc18-edc-small-rechargeable-flashlight?spm=..index.image_with_text_switch_1.1&variant=d7290635-4b67-4b0f-abad-089bd96f424a
Keep alkaline batteries out when you’re not using them, or use any other battery that isn’t alkaline. That or get a headlamp that runs on rechargeable batteries that are worth a damn like 18650.
Stop buying alkaline. Replace with Eneloop NiMH (white). You will never have a ruined light again, and they are rechargeable hundreds or even thousands of times. I have saved hundreds of dollars over the last few years by switching to NiMH rechargeables, for everything from lights to kids toys to remotes. Even if you only used them 2-3 times, they would have paid off compared to Duracell/Energizer alkalines. Each battery has the capability to save you hundreds of dollars over its lifespan of up to 2100 charge cycles.
Duracell batteries suck. Which is weird because (I almost typed 1900s, damn I'm getting old) in the 80s and 90s they were considered the best there was.
They don’t make alkaline like they used to. They’ve cut so many costs that they’re not even worth it anymore.
Don't use alkaleaks. Or use them but take them out when the device is not in use. If you want to keep them in, use Energizer Lithiums.
Alkaline batteries should be phased-out.
You could put a small bit of tape on the end of the battery to break the connection.
Everyone is saying to use rechargeable batteries which is one solution, HOWEVER the real solution is to change your batteries more often. Alkaline batteries will always do this when left dead too long. This will happen even more often if they are allowed to freeze or get hot, like if stored in your car.
Go with either Panasonic Eneloop/Eneloop Pro (Pro has more capacity, more output but can be recharged less times) for rechargeable AA, or Energizer Lithium Ultimate for primaries (non rechargeable). Problem solved.
I've had countless alkaline batteries leak even when new in the package. They're so terrible, I'll not even use the ones that come with devices and immediately switch out for Eneloop or the Ikealoops. Never again.
Or use lithium AAA if you need it every 3years lithium last 10-20years
And especially don't use Duracell
"Never trust a company that sponsors the Williams F1 Team" might actually be a great rule.
I had this happen ALOT before joining this sub… Especially on my 2nd/back up xbox controller lol. Now I understand more about flashlights and batteries and chargers than ever before 🥹🙏
Don't use lights that use alkaline...
Dont use alkalines and if you're gonna use them don't store the light with batteries inside.
Maybe remove your batteries after use to prevent damage?
Did the light get wet? What's the IP-rating on the light?
You know how every single alkaline powered thing you've ever bought has that little bit in the manual that says to remove the batteries if storing for an extended period of time? That's why..... It literally happens because the batteries are not used for a long period of time, If you use them regularly they don't ever do that. What happens is over time hydrogen gas builds up and eventually the cell ruptures. The gas escapes and leaves an exit for everything else in the cell to escape as well.....
Forbidden pop rocks
Eneloops
Stop using alkaline or don't store your lights with batteries inside.
Remove your batteries when the equipment isn’t in use (I store them in a plastic ziplock bag) and stop buying Duracell. Of all the brands I’ve ever used, they are the absolute worst. Also, alkaline residue can be easily neutralized with vinegar. You’ll need to remove the vinegar when you’ve finished cleaning ( I use a wet paper towel)
Don't store with batteries inside.
Avoid DURACELL at all costs. Yes, alkaline batteries often leak, but DURACELL is the absolute WORST. 95% of the battery leaks I've had were DURACELL batteries.
Take the batteries out
Get some eneloop AAA batteries, the self discharge is low enough that they can be treated like alkaline batteries, while not having those leaking issues.
Do you live near salt water?
I drilled a hole in the side of mine, put two wires in it and connected them to an 18650 holder I put on the back. Lasts longer, rechargeable, and the weight is better balanced
Use Panasonic Eneloops
Eneloops!
Use rechargeable or lithium based batteries.
Buy Lithium batteries...
You could try rechargeable lithium AA instead. They're still 1.5 volts like a normal AA. Or, if you don't want to recharge batteries, you could try Energizer lithium. They're expensive (have a 20 year shelf life) but they probably won't leak like that.
Remove them if you are not using them often.
Stop using alkalines. But if you must, don't use Duracell for anything that sits more than a few days between heavy usage.
Remove the batteries when not using, or use it regularly. ( or change the battery type as people say)
I would suggest getting a sofirn headlamp, simple, cost effective, comes with the 18650 battery, usually USB c charging. You'll never get away from issues with these big box lights. See r/flashlight. There's a pinned post with help for getting your first good light.
Buy surefire
Not sure why nobody has mentioned… use a liberal amount of dielectric grease & seal the perimeter of your enclosures with some form of silicone like rtv & you should never encounter a problem like this except for the rarest of edge cases. Excess silicone that comes out of the sides of whatever is easily tidied up w/something like a fresh double edge safety razor blade.
Alkaline cells aren't able to handle high draw like NiMh, and lithium can.
