WeRV Power powered by Prime Battery Solutions

What does CCA mean?

CCA, or cold cranking amps, is the current a battery can deliver to start an engine in a standard cold test. It is not the same as energy capacity in amp hours.

WeRV Power answer

Learn how cold cranking amps relate to starting an engine and why they do not measure deep cycle runtime.

What to check

Treat the result as a planning range. The exact fit and the install still get checked against the vehicle, the equipment and the battery maker.

  • Use the required CCA for starting jobs
  • Use Ah or Wh to plan runtime
  • Do not compare battery types by one rating
