12 years from original battery

I just charged the twenty four year old 6V Optima in the 1931 80R. I put it in the car in 1994, as a stop gap, when the five year old 46lb Interstate gave up. It seems to again have defied the odds and taken a full charge!

I bought a new Dodge Ram in 1998. The battery lasted 14 years. The battery in my 2014 Ram didn't even make it out of it's warranty.

I'm amazed at these battery longevity stories. The most I ever got out of one was 9 years on a Delco 6 volt I had in a '55 Plymouth, and I couldn't believe it. I do know that the batteries with the highest amp ratings last the longest but (especially on newer vehicles) they don't seem to last nearly as long as they used to.
