I bought a group 65 for an old Ford work truck. At six months old, I accidentally left the head lights on over night and after that it would not charge up with two dead cells. Walmart was nice enough to replace it, though. The replacement is has hung on for a bit more than a year, but I don't have high hopes for it's longevity. My brother put one in a 04 Grand Cherokee. He had to replace it after about a year and a half. He didn't drive it for 2 months and said it wouldn't charge up to 12 volts, so I'm assuming it had a bad cell.
I've had decent luck with the Costco Kirkland/Interstate batteries with the several that I've purchased over the years lasting well past the warranty date. Probably 5 to 7 years on average. I have a group 35 one of my vehicles that is 5 years old. I bought a carbon pile tester for myself for Christmas and checked all my batteries with it and that 5 year old Interstate puts out pretty close to it's rated cranking amps still.
