What Are Cold Cranking Amps

The battery’s Cold Cranking Amps is an essential measure for good cranking ability in cars, trucks and boats. CCA is the amount of current or amps a battery can provide at 0 °F for a 30-second duration until the battery voltage drops to unusable levels. For example, a 12-volt battery with a 650 CCA rating means the battery will provide 650 amps for 30 seconds at 0 °F before the voltage falls to 7.20 volts for a 12v battery. So in freezing temperatures, a higher CCA level is required to crank your engine. Also, as more cranking power is used, the amount of battery power available decreases.
