Group 31 batteries can come in a variety of different battery construction types. While most Group 31 batteries are lead-acid based, they break down into different product types based on how they are constructed. Understanding each Group 31 battery type will help ensure you are getting the correct battery for your application needs.
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.
