Only lasting two years isn't encouraging. I wonder why the short life? Were they the MAXX or the lower line of Wal-mart battery?
I now am running a six year old Interstate that I want to replace in the next month or two and would be dissapointed to purchase a new battery that didn't last but a few years now.
I just bought a costco Battery because I figured if for any reason I wasn't satisfied within the 36month during it's warranty period, Costco would be easiest to deal with. I wonld'nt even have to bother with saving my receipt, they can just look it up with my membership card.
The size I needed is 24F, the Duralast Gold and AAP diehard are both advertised as 750cca, where as walmart is a korean made 725cca or something... and the costco is speced at 700CCA.
Well, i still decided to go with costco since the original battery for my car was spec-ed at 582CCA, and even that lasted me more than 4 years
I took my battery tester with me to Costco and the first one i grabbed with the 03/21 sticker tested at 815CCA , 98% charged.
I was happy with that so I bought it.
I suggest go with Costco if you want a good deal on a good battery and hassle free return if it really does have to come to that.
