Umm, they are. How do you think they check warranty eligibility?




By the date you purchased the battery, which is the case with every single battery I've ever bought. The warranty has never been determined by the build date on the battery, only the purchase date on my receipt.

And those stickers.....they can be rather wrong to assume that's when the battery was manufactured. JC, for instance, will recharge batteries they have in inventory prior to shipping of they've been sitting 6 months. After recharging, a new date sticker is put on the battery, which makes it a very unreliable way to assure you've got a "freshly made" battery.

The only true way to figure out when a particular battery was manufactured is to be able to decipher the burned in codes on the battery's case, which cannot be changed. But, most people don't have access to what the codes on the case actually decipher to, so that info tends to be ignored.



So what if you can't find the receipt? The last time I read a battery warranty it said something like, The date of purchase determines warranty status, in absence of a store receipt, the manufacturing date on the battery determines warranty eligibility.

I saw something similar on an EverStart lawn mower battery at Walmart yesterday. The battery on my Troy-Bilt mower has the day it was charged rather than a manufactured date.

Walmart goes by the purchase date. But if you cannot find purchase date they will go by mfg date.

NAPA popped out the month and year circles on the purchased sticker before giving it to me. So no receipt needed.

being untrusting i am not happy about easily changed stickers, BUT with batteries shipped dry + stored dry time is NOT an issues + i read that the battery sellers activate them with acid only they have + will NOT sell to you. motorcycle batteries can be SOLD dry with sealed acid packs the buyer puts in + SPECIFIC charging instructions, how many parts sellers take the time to correctly activate a new dry shipped battery is the question, hence the recommendation to charge before installation. factory sealed batteries you just gotta trust the maker. in the past sealed batteries were coded with an embossing on the case, much better for sure

What sellers? I can't imagine the minimum wage employees at Walmart, Advance, Autozone handling caustic acid. This may have been how it was done 30 or 40 years ago, but most batteries today are sealed.
