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.
