Johnson Controls builds about 70% of the automotive/truck batteries out there. Each brand of battery (Delco, MoPar, Interstate, DieHard, etc) is built to the customers specification : i. e. numbar and size of plates size of tie bars, and material used in the separators- - - - so you can't depend on the Johnson Control name, but you can depend on the Cat, Delco, or MoPar names.
