I ran an Optima red top in the hot rod for 7 years. That's pretty good considering that it was a used battery when I got it. The Texas heat kills many batteries in 3 years.

I put another Optima in my 92 D250 Cummins (single battery truck) and it works great.

We are brothers and sisters doing time on the planet for better or worse. I'll take the better, if you don't mind.
