but does a car battery really age, even if it's not been used, BNIB?
yes. All batteries naturally drain that's why even AA batteries have expiration dates. I forget what the policy was at advance auto exactly, but I think after a year or two they're supposed to be sold at a discount. Our store never kept batteries long enough to deal with that.
personally i wouldnt want a battery over 6-8 months old. The newer the better
