Most battery warranties say that for X months, if the battery dies, they'll give you some portion of your money back. If you get a 60 month battery, and it dies after 30 months, they'll give you 50% of your money back (30/60). If you had a 72 month battery, you'll get 42/72 = 58% back. Why 42? That's the remaining life. If the 60 month is $70 bucks and the 72 is $85, and they both die at 30 months, you'll get $35 towards a new battery with the 60, and $50 towards a new one. That sounds good, but you'll still need a battery; another 60 will cost you $30, another 72 will be $35.
OK, if that wasn't confusing enough, which will last longer? Damn fine question. The theory is that the 72 should last longer. And that's true if you look at the population of batteries - it's a statistical thing. However, you're only buying one battery, so the 72 *should* last longer, but the only guarantee is that if it dies, you get money back. If you're stuck in a parking lot at midnight, this is little consolation.
My advice is unless the two are very close in price, I'd buy the 60 month battery and plan on replacing it after 4 years. The additional 12 months is probably closer to witchcraft than fact. Do you know you'll still have the car in 6 years?
