Car Battery Cca Test Results

1 cold cranking amps cca cold cranking amps cca is the recognized industry standard for rating a battery s performance.

Car battery cca test results.

If the open circuit voltage drops below 12 4 volt the battery needs to be recharged. Test cold cranking amps. Test and assessment of a start stop battery. Here are a few brief definitions of what your battery test is telling you about the health of your battery.

The battery test for an agm or efb battery is more extensive as the demands on these special battery technologies are more complex. A battery load tester is a device used for testing the condition of a battery including the analysis of the cca capacity of the battery. Cold cranking amps is a rating applied to car batteries expressing how much electricity flows from them at 0 f. A fully charged starter battery has a voltage of 12 8 volt.

What does your battery test result mean. Input your battery s cca rating number into your tester. A state of charge test does not indicate whether your battery is good. Anything below that should be recharged and tested with professional test equipment.

Switch your battery tester to cca cold cranking amps mode. The cold cranking amps rating for example 650 cca is an industry standard measure of how much electrical power a battery can provide at zero degrees fahrenheit. If your battery is greater than 12 45 volts it is sufficiently charged. To test the cca capacity of a battery using a load tester the battery must have at least 70 to 100 state of charge.

Battery voltage will change 01 volts for every 10 degree change in temperature. As the cca rating increases it indicates a higher powered battery.
