What is the difference between CCA and CA on a battery label?
Cold Cranking Amps (CCA) and Cranking Amps (CA) both measure a battery’s starting power, but CCA reflects performance at freezing temperatures (0°F), while CA measures at 32°F. For Northern Illinois drivers facing sub-zero winters, CCA is the critical rating to ensure reliable cold starts, as batteries deliver significantly less current at lower temperatures despite higher CA numbers.
