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)?
