In 1971 I bought a Firestone "Forever" battery for my Aston Martin DB4. As long as I owned the car, and had the paper warranty they covered it "forever". I think I went through 7 or 8 batteries over the next 35 years. I'd go to a dealer, and they didn't recognize it, I had them call corporate and they'd say "Yeah, OK" I did the same with Midas mufflers I went through two sets of 2 carbon steel mufflers and finally they patterned up some stainless steel ones for me.

Oh, original question, I'm still on the original car battery that starts my 08 Camry Hybrid seven years later. The hybrid battery seems to work fine as well. I seem to get about 3 years out of a battery for the 911, but it sits way too much.
