What Is The Difference Between CCA and MCA Ratings For My Car Battery?

The best Arizona and most reliable car batteries for automobiles in the desert southwest of Arizona.

Cold Cranking Amps (CCA) is a test conducted at 0 F (-18 C) for 30 seconds without falling below 7.2v at the battery's CCA rating.

Marine Cranking Amps (MCA) is a test conducted at 32 F (0 C) for 30 seconds without falling below 7.2v at the battery's MCA rating.

 

To pass the CCA test, a 700 CCA rated fully charged battery would be chilled to 0 F (-18C), then load tested at 700 amps for 30 seconds. To pass its rating, it has to maintain at or above 7.2 volts.

To calculate the MCA rating of a battery compared to its CCA rating, multiply by 1.25.
