i would have to respectfully disagree with scape-goat about wal-mart battery. they have a 3 year free replacement warranty, cost $59, are readily available. if and when it does go bad they don't give you any hassle, they just exchange it over the counter. i guess you would install it yourself,(but even at that they have free installation) because you're in this forum. it gives you a chance to clean the terminals and battery area really good. i always check the date code on the battery case and get a fresh one, they use the number for the year and the letter for the month, that way even if i lost my receipt they can scan the bar code and pro-rate the exchange. as you can see by my signature i have 6 cars so some tend to sit for awhile, that's a killer for batteries. even if i had to replace it at 3 years it's nice to know i now have a new battery, plus it was time to service the cables and box again anyway. i tend to keep my cars forever (that's why i'm looking for a m-b diesel) and have been using wal-mart for a long time with good results. this sounds like an ad for wal-mart but i don't have any affiliation with them. like the others said look at cranking amps. compare cranking amps to ca , cold cranking amps to cca or ca at 32 deg. good luck
