Cold cranking amperes

A measurement of the ability of the battery to start the car. The cold cranking amperage is expressed as a CCA value. Volvo batteries are usually marked with a CCA value according to the SAE norm. The cold cranking amperes according to the SAE norm is defined as the current that a fully charged battery can supply at a temperature of -17.8° C (0° F) for 30 seconds without the voltage dropping below 7.2 V. The higher the cold cranking amperes value, the better the starting capacity of the battery. In certain markets the batteries are marked according to the DIN norm.
