Car Batteries 101: What are Cold Cranking Amps?

Cold cranking amps rates how well a car battery can power a vehicle in cold temperature. A CCA rating measures how a fully charged battery starts a vehicle at zero degrees Fahrenheit for 30 seconds without dipping under 1.2 volts per cell or 7.2 volts for a 12-volt battery. A higher CCA rating means the battery has better starting power, which is important for drivers living in areas that consistently experience freezing temperatures.

Facts about CCA Rating on a Battery

  • The value rates a car battery's ability to run properly in freezing temperatures.
  • You should always consider the CCA rating if you live in an extremely cold climate.
