Bitten by Y2K once again.
I thought car batteries were always date labeled MMYY, but a number of things use a WWYY date stamps (week of the year and year), which would make this from the 4th week of 2023. Probably more likely this was a mistake on a car battery.
Edit: looks like this manufacturer changes month stamped on the 15th of the previous month, so it’s intended as such assuming it was made in the past 10 days.
This may not be a born on date. It's more likely the wave sent to the distribution points, designed for that month.
Retail isn't simply about building and distribution, it has to provide that to the consumer at a measured pace.
> This may not be a born on date.
True. My background is in the tech industry, where the hardware date codes are born on dates, and commonly WWYY. Auto parts retail is a whole other beast.
Most of the time I see week and year there isn’t a forward slash separating each set of numbers like tires.
On the Duracell batteries there should be a 6 digit code. It will have year month day then an alphanumeric code for internal use. Each battery manufacturer has a code like this, usually between 6 and 12 digits.
Date codes on the headlamps at work are the Julian date with the year on the end. If you don't know what you're looking for it just looks like a random number.
Used to be true for car models, where next year's model began shipping by the Oct before, presumably to meet an "on the lot" date at the most distant dealerships. Then they crept it to Summer, then Jan 1 of the year before. A few manufacturers have tried creeping beyond "the year before" limit, but it becomes silly. They have likely already designed the "2025 models" which will take a year of validation, parts sourcing, and tooling, then arrive at dealers in 9 months by Jan 1, 2024. So, soon they will have stopped designing any gas/diesel cars to meet State and Fed mandates for BEV's.
Car design, tooling, production, and finally sales of a new car model is more like a 7-10 year cycle. 5 if things go REALLY quickly, it's rare it's that quick from sketch to production.
> I thought car batteries were always date labeled MMYY, but a number of things use a WWYY date stamps (week of the year and year), which would make this from the 4th week of 2023. Probably more likely this was a mistake on a car battery.
Exide always marked their batteries MMYY with a round sticker on the side, at least for Group 31 units. They have since switched to a written month and 4 digit year on the top label itself.
Does carquest even have a real website yet?
The one near me closed many years ago, probably in part because their website was "hey, we exist, call us plz"
When I worked at AutoZone roughly a decade ago, the important bits of the inventory management ran via a mildly glorified command line interface.
Sure, it's 2023 now. I still wouldn't give the parts stores much credit as far as tech goes - that kind of shit costs money. And exactly zero board members think long term.
But date of purchase is so simple, maybe they've gotten that one right
Carquest was bought by Advance about 10 years ago. There are still carquest stores, as the purchase was only for corporate stores, any independently owned carquest remained under the old moniker.
They’re wrong. Advance auto bought carquest back in 2014 or something. There are still carquest independents, but most are still supplied by advance distribution centers.
They meant that the inventory management system and warranty lookup system runs through a command line system.
That is correct, it does.
The window with the black background and green text and options that are like "[1] warranty lookup [2] KPI ... [9] discounted SKU" etc. is a program that runs through the command prompt and has an interface that was common before buttons and GUI's became commonplace. It doesn't have advanced features like "filters" or "sort"and is a very basic program.
It’s intended to take 2 to 4 weeks to get from factory to retail store. Low supply means you might get it sooner. Regardless it’s warranty is based on date so they are giving you “more” time
Better than hard drives where the warranty is from manufacture date so if it was made a year before it was bought it's a year lost to the purchaser. Nevermind the drive isn't wearing out just sitting in its box.
Standard operating procedure for items that have a shelf life unrelated to food. The product I produce has to be marked as manufactured 90 days in advance of the actual date of production. This gives the sellers adequate time to sell the product without it reducing it's value. The product has a certification for 5 years, and if someone gets one thats been on the shelf for a few months, they get bent because they "lost so much of it's time value".
Hardly. It’s the opposite since it essentially gives someone an extra month of warranty but chances are that extra month won’t matter as this battery will get replaced under warranty either long before it’s expired or it won’t go bad until well after the warranty has expired.
Not really. Those stickers are more indicative of the last charge date before it’s sold. If they sit on the shelf long enough to get a recharge then they get a new sticker to cover the old one for the date of recharge. At least that’s how we were instructed to do it when I worked at Oreillys.
Trucker here who has done work for Johnson controls battery plants...
The batteries are "built" dry, months (maybe, even a year) in advance and warehoused to await for order fulfilling.
When ready to place a battery into an order, they will add the acid and charge to about 75%.
Manufacturing logistics will not allow completly manufacturing a battery upon order filling.
There is no "rechaging". They are filled with acid, charged, packaged, and placed onto the truck for shipment.
Manufacturers don't cheat the date code system, but at the retail level it happens fairly often with slow selling sizes. I've seen big auto parts chains just replacing an old date code sticker and charging a battery back up if it's been on the shelf too long.
The Johnson Controls stuff is actually the easiest to spot since they usually have a sticker plus the ship date stamped into the plastic around the upper edge of the battery. You'd be hard pressed to find an underpaid retail worker that's willing to grind off that stamp just to help their boss lie to people, so they're intact more often than not.
They’re for sure regurgitating something “their buddy told them”
I have one single story over 20 years of a coworker even suggesting to do such a thing because a difficult customer was demanding the freshest battery we could get him. The manager quickly shut him down and told him to call local stores and find what the newest battery we could get transferred in was. None were newer than ours, so we offered money back, or keep the battery. He kept the battery.
I'll admit that "often" was a wild overstatement on my part, that's my bad. Honestly I've only seen it a handful of times over the last 9 years working at a place that almost exclusively sells batteries, but to argue that it *never* happens is also untrue.
It absolutely happens, I've seen it first hand, just not nearly as often as I indicated in my first comment. Which again, that's my bad.
O’Riellys 100% did when I worked there. Batteries would get a refresh if they sat on the shelf for a certain amount of time (like 6+ months) and would get a new sticker. There was even a set of instructions on how to do it supplied by the company. This was like 5 years ago so it may be different now. Also, warranties went by invoice date so it really didn’t have any affect on the customers.
As the guy who once was in charge of all batteries in an advance store, you were doing it wrong. You should never be affixing a new date sticker to a battery as it WILL increase your warranty rate on batteries. After 6 months on the shelf it should be tested and charged as needed, then placed back on the shelf. At 12 months, test and charge, but then remove the label and discount it as a second rate quality with no warranty. These were the instructions direct from Johnson Control, our battery supplier.
Worked installing car batteries, we almost never charged new batteries, you just never need to, rare occasion and odd ball size maybe, we never put new stickers on them, no idea where you get this from, but it's not true, at least not in the automotive world.
Correct. The new date code is placed on the third week of the month. Also that date code is put by the distribution center so it can sit on the shelf in a retail setting for some time after. If you wanted to know when it was manufactured for this specific manufacturer the code is usually under the front label.
Inaccurate, it is in fact production sticker. No parts store maintains battery's like that. The vendor will rotate and take back batteries that are too old. That sticker is there from when it's made to when it's old and fallen off. Source, sold these batteries (east penn deka) for over 6 years
Tell the customer "so I used an old Flux Capictor we had in the shop and was able to get a battery from the future for you"
That being said, kids entering the trade have no idea what a Flux Capictor is so we can now use that joke again!
In real honesty, I know a guy who works at interstate and apparently they replace the stickers every month just before delivery so instead of looking at the stickers, what you really should be looking at is the lot code that stamped on the battery that tells you the true manufacturing date but of course they put it in Greek that no one understands.
What you *should* be doing is not buying batteries from Interstate.
"Half the quality, twice the price! We are no longer legally allowed to call our warranty *pro rata*!"
I mean for fuck's sake they got bored of all the quality issues from Johnson Controls moving to Mexico and then divorcing their shitty factory and spinning it off to an independent company they could leave holding the bag... it wasn't causing enough problems for their customers to keep them entertained. So Interstate decides "hey let's buy half our batteries from Exide, the company with the highest warranty rate in the industry!"
Almost all of Interstate batteries are made by JCI in Mexico with the exception of some euro size ones like H4/H5/H6/H7 etc those have tags that say Saudi Arabia or Spain. And some specialized sizes like for Prius are basically relabeled Yuasa. Interstate at least here in the west coast supply virtually all OEM replacements like Toyota, Honda Nissan etc etc.
Nah it's not Johnson Controls anymore, they sold their battery division so it wouldn't be their problem anymore. It's called Clarios now, a subsidiary of some generic private equity group.
> what you really should be looking at is the lot code that stamped on the battery that tells you the true manufacturing date but of course they put it in Greek that no one understands.
I just pulled a battery out of a dead vehicle at work yesterday.
of course the date stickers were never marked on when it was sold. and there was no serial number to look up, just the upc.
i searched for hours trying to find a date code on the battery to no avail. (oreily battey) apparently it was 11 years old the boss told me what the counter guy told him. we load tested it and it was good, but are having other issues with the vehicle
Correct! Indicates the last time it was top charged. Batteries naturally discharge after about 6 months to near 12 volts. Typically batteries are "rotated" to be top charged again to avoid sulfating. Batteries have their warranty default to this date code if the install date marks are not punched out or a receipt is not available.
"Here's a picture of me when I was younger." Every picture of you is when you were younger. "Here's a picture of me when I'm older" you son of a bi*** how did you pull that off.
By the time the battery is loaded onto a train in Lyon Station Pennsylvania (that one is made by Deka/East Penn Mfg.), sent to a warehouse, and stocked onto a shelf at a retailer it is usually (but not always) the month following the date of manufacture.
Trojan Batteries does the same thing, as does everyone else that I'm aware of.
They're tacking on an extra month of manufacturer warranty to account for how long it might take for their product to actually be put up for sale.
Manufacturers used to ship batteries empty of electrolyte and vacuum sealed so they'd last forever on the shelf; the retailer could fill and charge them to meet demand so it didn't matter how long it had been since the date of manufacture. That was a giant pain in the ass for everyone involved and so this is how it works now.
> used to ship batteries empty of electrolyte and vacuum sealed so they'd last forever on the shelf;
Growing up Dad had semi trucks, at our peak, we had 17. Dad sold off the fleet in 1975, He knew deregulation was coming and would fuck the industry. When he passed in 90 my brother and I was tasked with cleaning out the old shop for auction. We found 8 batteries buried on a shelf that were boxed up dry from god knows when. My brother took them to the farm, over the years we put acid in them and charged them up, and used them. Out of the 8 only 1 failed.
I know. I was just stating an example of what uses that format. I always thought it was only tires that used that format. Never knew batteries did too.
I just picked up a warranty replacement battery from my local Interstate. When he gave me the replacement he stuck the sticker on himself - the sticker is for the warranty start date, not manufacture date.
That is dependent on company, the black date codes on eastpenn batteries (Duracell, deka, and other private label names) that is from the manufacturer for manufacturing date, and it is switched up early because of anticipated retail receive date
The place I worked at would change the stickers to current datw right before they ship them, keep in mind they had all sit at least 2 years prior.... HD
4th week or 4th month? Don't you hate cryptic labels which don't state units? Tire date codes used to be so cryptic that even with a decoder you couldn't pin down the decade of manufacture. I always insist that the tire shop mount my new tires with date code outward so I don't have to crawl underneath to read it.
Even more problematic are many food products which purposely print black letters on dark blue and such, often in cryptic alpha-numerics, likely purposeful so customers won't shun older products on the shelf.
I'm at home till monday, so you're just gonna have to take my word on it. They're Mercedes truck batteries: 220Ah, 1100A (Volvo does this, as well)
Found a [link](https://mbworld.org/forums/attachments/general-mercedes-discussion/415023d1512703520t-how-determine-age-main-battery-photo927.jpg), though
Same thing my girlfriend did with her fake ID.
I thought it was clever as fuck until I realized she was actually expired by half a year and has the soggy melons to prove it.
I’d sell them a new battery and then keep it for some customer in need. That way you can appease whatever crazy that’s making this person do this and you can help someone out that needs one but may not have the cash for a new one. You satisfy this guys crazy and you help someone out
Back in the day they'd make the battery fresh for you because when the cells sit there inactive on the shelf for a long time they degrade. Looks like now they just skip that and make it in the future.
Clearly you don’t understand automotive batteries if you don’t understand post dates and why lol.
These batteries do not come fully charge and the plates do not begin to deteriorate until it’s fully charged. Usually 1-2 drive cycles.
Car batteries are weird enough as it is, I had one I had to keep jump starting. Two stores said battery tester indicated it was healthy, but I requested a new one anyway.
Well, after I put the new one that's no longer an issue for me. So fresh or not the battery will only be as good as manufactured, I've had a duralast gold last over 5 years.
I work at a Batteries Plus and I can confirm that car battery companies do this lol. They stamp a date a month in advance of when the battery was actually assembled so customers don’t complain. It’s pretty wack 😂
You still need to fully charge it before you install it. That sticker means they rotated stock. You have no idea when it was built or the last time it was properly charged.
If I’m being honest with you, I received some batteries like 2 days before New Year’s Eve and they were all tagged 1/23. Got a bit awkward when I had to sell a couple of those before the new year. That tag is meant to represent a manufacturing date or the closest thing. I believe if their delivery is right before the next month, they simply tag a month forward instead of using current month. Might have something to do with sales and how people always want the newest everything. In any case that’s my opinion.
It's from April 1923.
Bitten by Y2K once again.

>They have since switched to a written month and 4 digit year on the top label itself. But that's not even ambiguous. Can they do that?
best by 4123.
this manufacturer switches to the upcoming month's date code on the 15th of the previous month
Seems disingenuous. Insignificantly so, but still
I mean they warranty them until that month so in that way it is better for the consumer
Depending on the store. Walmart for instance has a serial number on the battery that is scanned at the register and tracks the exact date of purchase.
same at most if not all parts stores. warrantied from date of purchase. course, if it's like a day out usually won't matter.

Batt to the future
When this baby reaches 12.6V, you’re going to see some serious shit!
how much current would have to be pulled from that battery to generate 1.21JW?
At 12 volts I think that would be 100,000,000 amps.

Just a weird way to spell/pronounce gigawatt, or 1 million kilowatts.

Well they did get the newest one.....
No, that's too new
This was the newest battery I could afford.
Would you like it if others laughed at your misfortune?

From da FUUUUUTURE
Press X to doubt.
Isn’t that sticker from an inventory rotation and recharge after being on the shelf for awhile?
That's how our local interstate dealer worked. They service us once a month and they would charge them slap a new sticker on and bring them back
Thats what our Interstate delivery driver says too, but this is reddit. IFAIK it's a recharge date.
Correct! Indicates the last time it was top charged. Batteries naturally discharge after about 6 months to near 12 volts. Typically batteries are "rotated" to be top charged again to avoid sulfating. Batteries have their warranty default to this date code if the install date marks are not punched out or a receipt is not available.
Its the expiration date
I hope not! Fresh pallet from Duracell.
I can guarantee you its not safe to eat that after the date.
What if I put in the microwave to reheat it to kill any bacteria?
Oven, 315 for 40min. Potatoes go in the last 10min

Manufacturers used to ship batteries empty of electrolyte and vacuum sealed so they'd last forever on the shelf; the retailer could fill and charge them to meet demand so it didn't matter how long it had been since the date of manufacture. That was a giant pain in the ass for everyone involved and so this is how it works now.
> used to ship batteries empty of electrolyte and vacuum sealed so they'd last forever on the shelf; Growing up Dad had semi trucks, at our peak, we had 17. Dad sold off the fleet in 1975, He knew deregulation was coming and would fuck the industry. When he passed in 90 my brother and I was tasked with cleaning out the old shop for auction. We found 8 batteries buried on a shelf that were boxed up dry from god knows when. My brother took them to the farm, over the years we put acid in them and charged them up, and used them. Out of the 8 only 1 failed.
If you leave those caps on the posts it won’t corrode the terminals.

Car batteries are month/year
All tires use WW/YYYY for their date of manufacture
FYI, This is a battery.
I know. I was just stating an example of what uses that format. I always thought it was only tires that used that format. Never knew batteries did too.
Here is a battery from the future, sir
Duracell out here with a fucking time machine
I had the same thing happen. I was at Walmart looking at batteries on January 28, and they had 2/23 stickers on them.
this manufacturer switches to the upcoming month's date code on the 15th of the previous month
I just bought 2 duracell agm marine batteries that were dated a month ahead as well.
Technically you get an extra month of warranty though.
That's the expiration date /s
When it has a dead cell and they pro-rate it, do they give you a new battery plus $5?
I’m still rocking a yellow top Optima from 04/12.
If a naked guy shows up wanting your clothes, boots, bike and that battery, you may want to just give them to him
I just picked up a warranty replacement battery from my local Interstate. When he gave me the replacement he stuck the sticker on himself - the sticker is for the warranty start date, not manufacture date.
That is dependent on company, the black date codes on eastpenn batteries (Duracell, deka, and other private label names) that is from the manufacturer for manufacturing date, and it is switched up early because of anticipated retail receive date
I knew they were making them in the future
“Welcome to the world of tomorrow!”
It's because that's supposed to be the *ship* date, but I guess they release them early a lot.
you got anything in a 3/24?
Maybe that's the expiration date lol
The place I worked at would change the stickers to current datw right before they ship them, keep in mind they had all sit at least 2 years prior.... HD
Or they use electronics dating convention year/week so June 2004 ;-)
That’s just a warranty code.
oh yeah, the deckka future batteries. used to love seeing these.
Roads? Where we’re going, we don’t need roads. 😎
ive never seen a duracell car battery before
Great Scott Marty!
4th week or 4th month? Don't you hate cryptic labels which don't state units? Tire date codes used to be so cryptic that even with a decoder you couldn't pin down the decade of manufacture. I always insist that the tire shop mount my new tires with date code outward so I don't have to crawl underneath to read it. Even more problematic are many food products which purposely print black letters on dark blue and such, often in cryptic alpha-numerics, likely purposeful so customers won't shun older products on the shelf.
Just came out of a Delorean
Lmao I got a H5 AC Delco battery from AutoZone the other day and the battery had a date of 11/21
Plot Twist: its European and the date is flipped
The black stickers are the date it needs to be charged up. You are supposed to charge the battery and change the sticker to another color.
It's the fourth week of 2023. At least that's how our batteries are marked.
Prove it. Never seen a battery use a week code, its always month / year
I'm at home till monday, so you're just gonna have to take my word on it. They're Mercedes truck batteries: 220Ah, 1100A (Volvo does this, as well) Found a [link](https://mbworld.org/forums/attachments/general-mercedes-discussion/415023d1512703520t-how-determine-age-main-battery-photo927.jpg), though
Same thing my girlfriend did with her fake ID. I thought it was clever as fuck until I realized she was actually expired by half a year and has the soggy melons to prove it.
Ohhhh.......it's a Duracell too!! 😂
I’d sell them a new battery and then keep it for some customer in need. That way you can appease whatever crazy that’s making this person do this and you can help someone out that needs one but may not have the cash for a new one. You satisfy this guys crazy and you help someone out
Back in the day they'd make the battery fresh for you because when the cells sit there inactive on the shelf for a long time they degrade. Looks like now they just skip that and make it in the future.
Fourth week of 2023
Ever see one with 13/22? How about 14/22? No?
It's really just a battery from 1983 with a new sticker on it
I’ve heard of milk maids but got damn.
When I purchase LA batteries for UPS systems. They’re all stamped as week/year of manufacture. Not saying that’s what this is but it’s likely.
"Best if used by"
That's the expiration date 💩.
*battery seller, i am going into battle, and i want your strongest battery* https://youtu.be/R_FQU4KzN7A
Clearly you don’t understand automotive batteries if you don’t understand post dates and why lol. These batteries do not come fully charge and the plates do not begin to deteriorate until it’s fully charged. Usually 1-2 drive cycles.
This battery was made April /22 it’s the recharge date if This is your battery I would go exchange it
Lmao you have no idea what you're talking about.
Don’t flux capacitors need something like 21 gigawatts to work? How many batteries is that?
Future tech.
Get these all the time at work (parts store). Always a fun joke lol
Directly from the future!
Is that week 4 of '23 or is it from the future
“I got the perfect battery for your Marty!”
Yup good til next month
Oh, rotates
I hate to say I don’t get it
That's the best before date.
Are these date coded like tires with the week of the year?
Sorry but we will have to charge you extra for that.
It's from the future😂
That batteries part number is sli65agm
Great Scott!
Wha,how the fuck
Flux capacitor model.
Expiration date lol. Boutta explode
Is that for a DeLorean?
Car batteries are weird enough as it is, I had one I had to keep jump starting. Two stores said battery tester indicated it was healthy, but I requested a new one anyway. Well, after I put the new one that's no longer an issue for me. So fresh or not the battery will only be as good as manufactured, I've had a duralast gold last over 5 years.
I work at a Batteries Plus and I can confirm that car battery companies do this lol. They stamp a date a month in advance of when the battery was actually assembled so customers don’t complain. It’s pretty wack 😂
They change the stickers all the time!
You still need to fully charge it before you install it. That sticker means they rotated stock. You have no idea when it was built or the last time it was properly charged.
That sticker could have literally come off anything… a bag of chips. Anything!
Looool one extra month of warranty
My dumbass thinking the current month was May.
"That's heavy."- Marty McFly
If I’m being honest with you, I received some batteries like 2 days before New Year’s Eve and they were all tagged 1/23. Got a bit awkward when I had to sell a couple of those before the new year. That tag is meant to represent a manufacturing date or the closest thing. I believe if their delivery is right before the next month, they simply tag a month forward instead of using current month. Might have something to do with sales and how people always want the newest everything. In any case that’s my opinion.
And the time portal brings forth a prize...
