Yes, they do, and at least in theory a larger (higher CCA) battery should last longer.
But a lot of other factors affect battery life, and at least in my limited experience, they make a lot more difference. Leaving the
lights on, for example, can significantly reduce battery life every time it happens.
My experience with Costco batteries has not been perfect; in fact I just replaced one that was only a few months old but had lost
nearly all of its capacity. But, their return policy is so great that I plan to buy all my batteries there from now on. The only
question they asked me was "Is it defective.", and they gave me a 100% refund (no pro-ration, not just a credit against a purchase)
including tax & core charge. Both on the battery that was only a few months old, and it's predecessor (which lasted about 4 years).
By comparison, when I tried to return a 4 year old battery to O'Reillys, they initially refused to even give me credit towards a
replacement. After a certain amount of heated discussion with the manager (there was a "72 month" sticker right on the battery, no
matter what their computer said), they did give me some credit towards a new battery, but not enough to cover the increase in price.
And the new one is only warrantied for 2 years.
