Battery Cca Rating Cold Cranking Amps Chart

Cold cranking amps cca cca is a rating used in the battery industry to define a battery s ability to start an engine in cold temperatures.

Battery cca rating cold cranking amps chart. Hca ca or mca numbers may look higher than the cca number but because these tests take place at 32 degrees and 80 degrees fahrenheit they are not equal to ccas. It still holds up to now. Cca cold cranking amperes is the most popular industry rating and is a measurement of the current a fully charged battery can deliver for 30 seconds and maintain a voltage of 7 2 volts 12 volt battery at a temperature of 18 c. A large number of batteries use cca to present the battery s ability to start an engine at certain temperatures usually ranging between 30 32 degrees fahrenheit.

What are cold cranking amps cca and ampere hours ah. Why did cca ratings become so popular. A battery should meet or exceed the manufacturer s recommendations for cranking amps or cold cranking amps but in most cases buying a battery with an extra 300 ccas isn t necessary and will probably cost more money.

Refer to the latest version of bulletin 15 06 03 002 for more information. Cca stands for cold cranking amps.

The chart includes cold cranking amperage cca ratings and identifies the type of battery. The rating refers to the number of amps a 12 volt battery can deliver at 0 f for 30 seconds while maintaining a voltage of at least 7 2 volts. The rating refers to the number of amps a 12 volt battery can deliver at 0 f for 30. What are cold cranking amps.

However you should not confuse it with ca or. Choose a battery based on ccas instead. The cca rating refers to a battery s ability in low temperatures or more precisely how efficient it is in kicking an engine off when the weather is cold. As simple as it sounds it s clear that this rating is more important when you live in a cold region where the temperature often.

The higher the cca or cold cranking amps of the cell the best it is for your car or vehicle.
