Recommend cold crank amps?

There used to be 3 battery manufacturers in the US.. Delphi/(Delco), Exide, and Johnson Controls..

Johnson Controls bought Delphi in IIRC 2006,,

Johnson Controls also makes Optima Batteries..

All white cased batteries,, no matter what name are made by Johnson Controls,, Interstate,, Walmart ,, boJangles,, whatever = Johnson Controls

All black cased batteries are made by Exide,, no matter the name on it...

This does not include Offshore white/black/pink batteries..

Google it,, I did..

cheers..
