Price shopping:

Looks like Walmart would be the best deal (cheapest + longest warranty if you count the prorated 24 months as well) if it was stocked anywhere, but the AH is unknown. Of the known AH batteries the Duracell from Batteries Plus may be the best for me since it has an extra year warranty for $7 more than Autozone, will the 92ah vs stock 90ah matter?



Known AH batteries:

Batteries Plus Duracell Ultra battery - 92AH, $196 after tax and core refund using coupon CDP10011, 48 month warranty = https://www.batteriesplus.com/productdetails/sli49agm

Autozone Duralast battery - 92AH, $189 after tax and core refund, 36 month warranty = Duralast Platinum/Battery H8-AGM - Read 6 Reviews on Duralast Platinum #H8-AGM

BMW East Penn battery - 90AH, $193-257 before tax depending on battery amperage (quick price quote from friend at dealer before I knew 90AH), unknown warranty


Unknown AH batteries:

Walmart EverStart battery - unknown AH, $150 after tax and after unknown core charge, 36 month warranty + 24 month proration = EverStart Platinum AGM Battery, Group Size H8 - Walmart.com (unfortunately it does not appear to be in stock anywhere)
