Central Kansas
If the designation for Optima is based on the top color....I assume that the proper cold cranking amps and old designation of group size is sufficient for the Cummins in the Dodge? Maybe with these type of batts that is a mute point if one 12volt red top Optima can replace those huge old 6 volts in a 4430.
Are spiral cells the way to go for truck batteries?
