It's just another way to test batteries.
Cold Cranking Amps (CCA) is the current at which a battery will sustain a terminal voltage of at least 1.2 Volts per cell for 30 seconds at -18 degrees Celsius.
Cranking Amps (CA) is the same test, at 0 degrees C.
Pulse Hot Cranking Amps (PHCA) is the same test, at 25 degrees C, and for five seconds instead of thirty.
