To be honest, the Duralast Gold that Autozone sells has been a REALLY good battery for me. One lasted nearly 10 years in my Dakota.

I've listened in on posts on a Cummins site and basically all batteries are made by two or three manufacturers. Age has set in on my brain. I know that Johnson Controls is one of them. Each vendor orders batteries to their specs. The more cold cranking amps, the more plates in the battery. The battery last longer. I need two for my truck and I will probably go to Autozone. Good warranty on the Golds.
