The last Sunday of August (August 30, 2009), I had to buy a new battery for my 1981 Monte Carlo SC. I've owned this car since December 1999 (when I bought it from my parents) and have not previously replaced the battery during my time as owner. The old battery was a GM/AC Delco battery.
So ... I asked Dad to look through his records to find out when that battery was installed. He looked and found that it was bought and installed February 4, 1997. The '81 MC SC had 167,000 miles at that time. When I replaced that battery, the car had 192,000 miles.
Thus ... that GM/AC Delco battery lasted over 12.5 years ... and 25,000 miles.
What is the longest a battery has lasted in your car(s)?

Well, I think the longest one was about 5 years, Everything else kind of dies after a year or two, Fortunatly, I just keep warrantying them at the shop, I really haven't paid for a battery in a while, LOL!

well this is a record breaker,, when I got my moms 87 monte in 2002 it had a interstate in it. I didnt know how old it was at the time but it lasted until 2006. We have a interstate dealer in our area that offers "blems" for $25 so i took the old interstate out and went to purchase a blem. The guy at interstate said the date on the old one was from 92 meaning i got 14 years out of that one
the AC delco in the 71 is going on 7 years now the interstate i have in the 86 is the $25 blem out of my old 87 monte thats 3 years old.
