Cranking Amps (CA) - A rating that is used to define the battery's ability to start an engine in moderate temperature conditions. BCI (Battery Council International) defines it as "the discharge load in amps that a new, fully-charged battery at 32ºF (0ºC) can continuously deliver for 30 seconds while maintaining a terminal voltage equal to or higher than 1.20 volts per cell." This artificially high rating should not be confused with CCA, which is conducted at 0ºF (-17.8ºC).
