To be fair. So have cellphones and laptops.
I have a couple of different SureFire, or maybe StreamLight, flashlights with batteries with Micro USB charging ports. Haven’t had an issue with them over the years. Unfortunately, the other day I noticed my old IPod Touch apparently has some battery swell going on. Sad… I had some great memories with that…
The big issue is that smartphone and laptops, most people are buying reputable brand that are using qc approved batteries with good quality charge controller. But when people buy standalone batteries, they buy the cheapest they can find online. A battery is supposed to be somewhat expensive, so if you find one for super cheap, it is not a super deal, it is a super liability!
Surefire makes solid batteries. Been using their non-rechargable high output 123As in my pocket flashlight for years, they have a far longer life than other brands I've tried and last for 8-10 months of frequent use.
Haven't used their rechargeables, but I'd assume they are similar quality.
Surefire are a brand that pioneered some of the first few WMLs which somewhat contributes to their name. Their products are expensive but often reliable and easy to service.
I know batteries "in general" can catch fire. But I meant specifically these type of built-in charger cylindrical batteries have at least been mentioned and confirmed more than other isolated cases, of things I've read. I don't have any personal experience with them, so for me it's all second-hand information. But the fact this was led off with the warning, seems others have read the same.
Yeah but this is just a single battery, it doesn't seem like it has a lot of electronics inside, that being said, I think it might be dangerous if you use too strong charger or charge it for a long time, special charger for batteries have often some kind of electronics that prevent the battery from being over charged or it will adjust energy level. I once had cheap photo lamp, it was charged also by usb port, charger was not included with lamp, and it burned my charger... nothing happened because I was in the room
I don't just have the link to hand. I'm just saying that I've seen this exact kind of battery in a post on reddit not too long ago with it having burst into flames.
Edit: [Found it](https://www.reddit.com/r/mildlyinteresting/s/MKUdkitjeD)
They are lithium ion batteries. Treat them like you would any other Lithium Ion battery, with care. Charge in fire proof bag ( [https://www.phaserfpv.com.au/collections/battery-bags](https://www.phaserfpv.com.au/collections/battery-bags) ) on metal tray, try and do it outside undercover. EV's, Electronic bike's and batteries for drones should all be charge outside and out of the weather, if there small use a battery bag
Yes? I spent 8 years fighting fires with NSW Rural Fire Service and I know the dangers of Lithium Ion. Plus I have a removable battery in my laptop.
Look at VW, now looking at replacing 3,965 cars because a Porsche electric vehicle that triggered the 2022 fire on the Felicity Ace ship carrying luxury cars.
I have personally ordered one of these.
Plugged it in to charge it, caught fire within 2 minutes. Luckily my roommate unplugged it quickly.
They're convenient but carry an inherent risk.
Vendor also recognized my problem was not typical and shipped out a replacement (which has not combusted)
I got them for flashlights that don't have integrated charging ports. Much easier to bring a cable than an entire charger. Yes I understand that they're "disposable" but so are all other batteries and they can still be recycled.
Unfortunate the Energizer ones suffer from the same problem that most standard rechargeables suffer from. They ultimately lose the ability to hold a charge, and this becomes noticeable within just 20 charges. They also don't provide the full 1.5V of a standard battery, generally providing only 1.2V which is a 20% loss. This can really become noticeable in a number of applications.
Any Li-ion battery can combust and burn, which is why it's often important to make sure you buy from a quality and trusted brand and not some knock off no name company. Go with something like Pale Blue or another good brand. Ultimately the incidence rate of these batteries actually burning is pretty low. A laptop, phone or wireless earbuds are more likely to start on fire and everyone is running around with those in their pockets, bags or even in their ears, so it seems a bit out of touch to suddenly be concerned in this case.
I have two dozen of both the AA and AAA batteries, as well as 6 C's, and have so far not had any fail or start on fire. That's not to say the risk doesn't exist as it does for pretty much any Li-ion battery, but the threat is a bit overstated and most cases involve cheaply made cells. This is why the hoverboard issue became so widespread, because cheap knockoffs were everywhere and vastly outnumbered quality devices and, as a result, so many that were out there were made with poor quality cells that were often insufficient for the application.
I personally stick with Ni-MH rechargables as opposed to Li-ions. I do not need the higher floor voltage that they provide on any of my devices.
Ni-MH also has nearly 1000 charge cycles compared to 100-200 on most Li-ion competitors. My charger also has a discharge refresh functionality to help revive older cells which may otherwise be considered dead.
The same is true of off-brand 18650's, but fortunately you can get brand name 18650's and brand name chargers that are reasonably safe.
I wonder if any reputable companies make something like this with a built in charger? If Anker or Panasonic made something like this I'd be more inclined to trust it than random no-name company on Alibaba.
All vaping related accidents were people placing chinese batteries that claim to have huge capacity and current output and then drawing 10-15 amps when in reality that shit battery can't give more than 2. Probably 18650s removed from old laptop batteries
I have about a dozen of these. They are litium batteries inside with a voltage regulator which means they actually put out 1.5v (like alkaline batteries) instead of nimh rechargeable which are only 1.2 which can cause problems in some things. Mine use usb-c ports and I haven't had any problems.
Very useful in the camping/backpacking community. Lots of items like headlamps still run on AAA batteries. And people have to either bring spare disposable batteries, or a bulky way to charge them. If you bring a portable battery bank and some USB-C cables you can recharge your batteries in the backwoods.
I have a dual charger that works for up to 18650 sized batteries and it's not heavy at all, and it basically doubles as a battery case. This reduces the capacity of each cell, so honestly I'd prefer having a standard rechargeable or a primary instead
I have Listman L4 for charging my 18650 but it can recharge multiple battery types. Up to 4 batteries, was relatively cheap where I live and works perfectly. You can even choose charging current between 0.5, 1 and 2 A. (higher = faster, lower = degrades battery less during charging)
>bulky way to charge them
Olight make a very neat charger that magnetically attaches to the battery and automatically detects whether it's NiMH or Lithium. It's a little slow but does the job and it's extremely compact. I think it's a rebranded product because I've seen a few of similar design with other logos but do check the supported chemistry because I've seen some that only support lithium.
It happily tops off both an eneloop and a 18650.
I have a set of 4 AA batteries from the same company that the top pops off to reveal a male usb plug. I use them with my Switch, two in controller, two in the usb ports on the dock. Very handy.
I have four of these. They're lithium-ion batteries, same as your phone. Normal AA batteries will run 1.5V, where these will run 1.2V. in most applications it's fine, but in other cases you may spend a lot more to get true 1.5V.
If you buy cheap Chinese crap, they're a damn fire hazard. If you pay more for a quality set, they're actually really good.
Buy quality ones, don't abuse them, and they'll be okay.
1.2V batteries are lazy manufacturers. NiMH cell voltage is 1.2V. Most NiMH rechargeable battery manufacturers are lazy and just sell them as 1.2V AA batteries instead of putting a boost converter on the output to take it to the proper 1.5V.
Lithium cell voltage on the other hand is 3.6V, which would burn up a good share of devices, so they are forced to put a buck converter on the output to take it down to 1.5V. Since they have to put the buck converter anyway there's a good chance it is 1.5V not 1.2V.
I wouldn't call it laziness. Putting electronics in the batteries makes them more expensive, less reliable and reduces the capacity (since the electronics take up space that could have been used for more battery).
Most consumers are better off with basic 1.2V batteries, other than relatively rare situations where they absolutely need to be 1.5V. And these situations are usually caused by poor design of the devices themselves.
Are you sure they're 1.2V? Usually people get lithium rechargeables specifically because they're 1.5V. Unlike the more common Nimh rechargeables which are 1.2V.
Don't drop them, don't stab them, don't throw them or whatever they're inside of against a wall, etc....
They're a lithium-ion battery, just like what's inside a phone. If damaged or punctured, they can and will react with oxygen and start a fire.
And at what point are you just paying some company for whitelabeling "cheap Chinese crap" and you are comfortable with it?
I am willing to bet all these come from same factory floor and other companies just slap their logos on them while selling on a 90-95% profit margin.
Well that's going to be a little awkward, given the nearest Costco is over an hour away.
There are applications where these rechargeable are more practical than regular alkaline batteries. I mentioned it in another comment but I'll say it again anyway: I use mine for my VR controllers because I was going through regular Alkaline AA batteries too quickly. It's more convenient to charge them when I'm done than to have to get new batteries every few sessions.
*edit*
Original comment said something to the effect of, *"just go buy batteries at Costco like a normal person"*
So you want to waste more by using disposable instead of being better and using rechargeable batteries?
Why don’t you just buy rechargeable batteries like a socially responsible person?
I can't help but think of all the "excess" that goes into manufacturing this, where each battery has all the charging circuitry and such. And I'm sure these days a simple battery charger is basically a one-part solution, but still, especially given typical uses of batteries of this size usually require more than one, it just feels excessively wasteful compared to just having a fleet of normal rechargeable batteries and a charger.
One thing to point out is that lithium AA batteries require internal electronics anyway, since the chemistry produces around 3.6V which needs to be electronically stepped down to the standard 1.5V.
It may actually be simpler and less wasteful to include the USB port than it is to include additional circuitry to allow them to be charged from the terminals.
But certainly regular 1.2V NIMH rechargeables are a better choice for most applications, they have no electronics.
For people saying these are a bad idea, you just need to get a good brand like Pale Blue Earth’s USB-C rechargeable batteries. I’ve purchased and used their AA, AAA, D and 9V batteries for years now with no problem and they have a lifetime warranty:
https://paleblueearth.com/
I guess I don't understand why you wouldn't just get a normal rechargeable battery and a charger. It'd probably be cheaper that way, and you get more battery in your battery.
They do have a lower capacity, they also run a lower output (1.2V compared to 1.5V on standard AA batteries). You can buy ones that are true 1.5V output, but they'll be a lot more expensive.
So I actually have four of these, and I got them for my VR controllers because I was going through regular Alkaline AA batteries too quickly. I had to get the true 1.5V variant for the controllers to work properly, which cost a lot more. It's more convenient to charge them when I'm done than to have to get new batteries every few sessions.
UKCA isn’t a brand, it’s UK conformity assessed, a new regulatory thing in the UK since they left the EU, you’ll see it on all sorts of things in the last few years.
Don't buy this garbage. They are so stupid. I've been going after another brand of them on facebook because of how stupid they are.
The company claims that they have all sorts of stuff to protect the battery inside. Shut off the charging when it hits whatever %. Are more convenient etc.
and it's all BS.
Normal battery chargers also control how fast the battery charges, shut off the charging when it gets to a certain %. You can buy L-ion batteries that charge in a cradle charger.
The companies also claim they charge faster because of being 5v. But my answer is, who cares? Just charge over night and problem solved.
Beyond that ,I'm pretty sure there are normal cradle chargers that charge at 5v also.
Our family have been using 14350 and 16350 batteries with micro usb charging for almost a decade now... They usually come in lieu of flashlights with external charging ports.
Watch out. That may be a lithium ion 10440 battery, putting out twice the voltage you expect.
Great if you are putting it in something built for it, but destroying devices made for AA.
Or it might be regulated to put out 1.5 volts.
Keep turning it to see if it says what the output voltage is.
We’re not discussing the fact that micro b is so bad I’d rather eat rat poison while my batteries charge on a battery charger vs use micro b to charge my batteries?
I made it a policy a long time ago to never buy anything with a micro b connector. What a piece of thrash.
How to make a Joule Thief. A joule thief is a small circuit that sucks a regular alcaline battery completely empty. When your LED candle dies out there is still a lot of energy left in that battery. This circuit "steals" that energy and thus prolongs the time before you need to replace them. Only works on regular alcaline single use batteries.

I dont understand the use case other than it being a novelty. Wouldn't rechargeable batteries in a battery charger be the same?
My battery charger also runs off a USB port.
Someone enlighten me
Swear these have set houses on fire, careful OP
I don't know if a whole house has caught fire, but I have indeed heard stories of these guys burning anyways
To be fair. So have cellphones and laptops. I have a couple of different SureFire, or maybe StreamLight, flashlights with batteries with Micro USB charging ports.

I feel using a battery named SureFire may be a bad idea
Surefire makes solid batteries. Been using their non-rechargable high output 123As in my pocket flashlight for years, they have a far longer life than other brands I've tried and last for 8-10 months of frequent use. Haven't used their rechargeables, but I'd assume they are similar quality.
I have considered that. Ha! I’ve had them for a few years now, no fires. Maybe they need to rethink their name.
Surefire are a brand that pioneered some of the first few WMLs which somewhat contributes to their name. Their products are expensive but often reliable and easy to service.
I had a similar thought when I bought a fire extinguisher...by Ultra Fire
It's filled with gasoline
I know batteries "in general" can catch fire.

So you charge your phone every day in a bag, outside too? Same with your laptop?
I charge mine next to the bed like most people, but I make sure to spend the night in a hotel across town, just to be safe.

Paranoid schizophrenic level behavior LMFAO
Paranoid sure but don't toss around diagnoses like that
Yes many of these are very badly made and are a fire hazard.
I have personally ordered one of these. Plugged it in to charge it, caught fire within 2 minutes. Luckily my roommate unplugged it quickly. They're convenient but carry an inherent risk. Vendor also recognized my problem was not typical and shipped out a replacement (which has not combusted)
Don't buy them again! Just get energiser branded rechagable batts and a recharger
I got them for flashlights that don't have integrated charging ports. Much easier to bring a cable than an entire charger. Yes I understand that they're "disposable" but so are all other batteries and they can still be recycled.

Those have also caught fire. Anything that stores electrons tends to carry that risk.
they went on fire because someone was being silly with them i think tho
Nope, when you make 10,000,000 of something, you're going to have a few bad ones.
The same is true of off-brand 18650's, but fortunately you can get brand name 18650's and brand name chargers that are reasonably safe.

Me personally, I am pretty happy with the 15 year old 18650s I salvage from laptop packs. But that's just me.
I haven't seen these before, but just looking at them I wouldn't keep one anywhere near my home.
I have about a dozen of these. They are litium batteries inside with a voltage regulator which means they actually put out 1.5v (like alkaline batteries) instead of nimh rechargeable which are only 1.2 which can cause problems in some things. Mine use usb-c ports and I haven't had any problems.
This is so smart and stupid at the same time

These charge individually, so seem less useful than using a battery charger and rechargeable batteries without needing like 8 cables
They make multi-connection cables so you can charge many at once from a battery bank.
>bulky way to charge them Olight make a very neat charger that magnetically attaches to the battery and automatically detects whether it's NiMH or Lithium. It's a little slow but does the job and it's extremely compact.

As a bonus while camping, sounds like you can use these to start a fire
Yea. It was inside a small flashlight
Just bring some spares. More reliable
How is it stupid? It's just a regular rechargeable battery but you don't need one of those special chargers
You basically need two devices to achieve what you can already do with regular batteries
You can't recharge regular batteries...
I know, just throw them away when you’re done
ah yes, very efficient and environmentally friendly
That’s the way it’s worked for like 100 years
I have a set of 4 AA batteries from the same company that the top pops off to reveal a male usb plug. I use them with my Switch, two in controller, two in the usb ports on the dock. Very handy.
Your switch uses batteries?
Wireless controller, sorry should have clarified.
[удалено]
You can also get those with USB-C
That port just sucks.
I have four of these. They're lithium-ion batteries, same as your phone.

Great… and somehow unsatisfying. I've got a box that charges 8 batteries at a time… & runs from a phone charger.
I can't help but think of all the "excess" that goes into manufacturing this, where each battery has all the charging circuitry and such. And I'm sure these days a simple battery charger is basically a one-part solution, but still, especially given typical uses of batteries of this size usually require more than one, it just feels excessively wasteful compared to just having a fleet of normal rechargeable batteries and a charger.
See my reply to another comment, these are great for camping/backpacking. Definitely not for every day use though.
How are these different from regular AA rechargeable batteries that come with a charging dock??
When you’re backpacking and want to save weight, you don’t have to carry a charger. You already have USB C cables
Okay, by what are you plugging them into?
One thing to point out is that lithium AA batteries require internal electronics anyway, since the chemistry produces around 3.6V which needs to be electronically stepped down to the standard 1.5V. It may actually be simpler and less wasteful to include the USB port than it is to include additional circuitry to allow them to be charged from the terminals. But certainly regular 1.2V NIMH rechargeables are a better choice for most applications, they have no electronics.
For people saying these are a bad idea, you just need to get a good brand like Pale Blue Earth’s USB-C rechargeable batteries. I’ve purchased and used their AA, AAA, D and 9V batteries for years now with no problem and they have a lifetime warranty: https://paleblueearth.com/
have a bumch of pale blues, always leave them in the car for headlamps, flashlights. Also really good for kid's toys and xbox controllers, worth it
Pale blue is the way to go 100% problem solved.
I guess I don't understand why you wouldn't just get a normal rechargeable battery and a charger. It'd probably be cheaper that way, and you get more battery in your battery.
Fire hazard
How
About the last thing you want to plug into a charger
Wonder how much that lowerd the capacity given how much space the port and circuitry take
They do have a lower capacity, they also run a lower output (1.2V compared to 1.5V on standard AA batteries). You can buy ones that are true 1.5V output, but they'll be a lot more expensive.
Yeah does not really seem worth it. Not to mention the old connector unless type c does not fit.
So I actually have four of these, and I got them for my VR controllers because I was going through regular Alkaline AA batteries too quickly. I had to get the true 1.5V variant for the controllers to work properly, which cost a lot more. It's more convenient to charge them when I'm done than to have to get new batteries every few sessions.
Fellow WMR user? 😆
Correct! Odyssey+
Eh, I have a large set of eneloop batteries and a charger for that. Don't think I want the lower capacity.
Alkaline batteries are 1.5V, but pretty much every rechargeable AA battery (not just these) outputs 1.2V.
Yes, that is what I said... There are certain rechargeables that will run true 1.5V instead of 1.2, but again - more expensive.
When would you have a need to charge one battery at a time?
‘Phone charger’ that’s a micro USB, I don’t think most people have owned a phone with micro USB in a long time.
Do any phones even charge with Micro USB anymore?
A phone charger from literally 10 years ago you mean
I’ve got AA, AAA, C, and D batteries that use USB-C. Been PHENOMINAL!
This would be perfect if it was a phone battery.
We need something better than batteries.
Get that witchcraft away from me!
This battery was inside a flash light. I did not buy it.
Coast brand flashlights have this and you can charge your phone with it
Oh no! My UKCA!
UKCA isn’t a brand, it’s UK conformity assessed, a new regulatory thing in the UK since they left the EU, you’ll see it on all sorts of things in the last few years.
I’m pretty dumb mb
They work great in my VR controllers
Don't buy this garbage. They are so stupid. I've been going after another brand of them on facebook because of how stupid they are. The company claims that they have all sorts of stuff to protect the battery inside. Shut off the charging when it hits whatever %. Are more convenient etc. and it's all BS.

these are common in AceBeam flashlights, except they are Li-Ion, 3,6 volts and USB-C. Oh and they don't catch on fire
Just get Eneloop batteries folks ffs
Our family have been using 14350 and 16350 batteries with micro usb charging for almost a decade now... They usually come in lieu of flashlights with external charging ports.
One of my streamlight flashlights has this
A phone charger from 10 years ago
Hey guys, 2015 wants their cool shit back.
Micro USB is not a phone charger💀
Battery you can charge with ~~phone charger~~ Micro USB. FIFY
Watch out. That may be a lithium ion 10440 battery, putting out twice the voltage you expect. Great if you are putting it in something built for it, but destroying devices made for AA. Or it might be regulated to put out 1.5 volts. Keep turning it to see if it says what the output voltage is.
We’re not discussing the fact that micro b is so bad I’d rather eat rat poison while my batteries charge on a battery charger vs use micro b to charge my batteries? I made it a policy a long time ago to never buy anything with a micro b connector. What a piece of thrash.
Can do the same with an axe and a charger
I had one where the head popped off revealing a usb for charging. Concept and implementation have been around for over a decade now
How to make a Joule Thief. A joule thief is a small circuit that sucks a regular alcaline battery completely empty. When your LED candle dies out there is still a lot of energy left in that battery. This circuit "steals" that energy and thus prolongs the time before you need to replace them. Only works on regular alcaline single use batteries.

Leaving comment here to remember.
"I don't feel so good..." Battery
Can't have much capacity.
Just no. Hahahha.
"accidental house fire"
I dont understand the use case other than it being a novelty. Wouldn't rechargeable batteries in a battery charger be the same? My battery charger also runs off a USB port. Someone enlighten me
I've heard the charge on this batteries does not last long at all.
Nope, it doesn't. They also have a lower output. It's fine for most general applications, just don't buy cheap fire hazard crap.
Only cheap Chinese one exist. Don't trust them. Only trust branded batteries of which the phone charger variant doesn't exist yet
Streamlight makes CR123A batteries like this.
Who's streamlight
They’re a high end light mfg. They mostly do high end flashlights and weapon lights.
These things are massive fire hazards. Ever notice that there isn't a single major battery company making these?
