What are Marine Cranking Amps (MCA) or (CA) rates?

Postby admin » Tue Nov 08, 2011 4:18 pm

This is a rating used to describe the discharge load in amperes which a new, fully charged battery at 32 degrees F (0C), can continuously deliver for 30 seconds and maintain a terminal voltage equal or greater than 1.2 volts per cell. It is sometimes referred to as Marine Cranking Amps or Cranking Amps.
BCI has established testing proceedures for battery specifications of CCA (Cold Cranking Amps) and CA (Cranking Amps).
At this time all of Braille’s ratings are determined by using a conductance tester and not the draw down method used by the BCI. For more information on Conductance Testing, please see this link:Conductance Testing Method
