Battery voltage will change 01 volts for every 10 degree change in temperature.
Car battery cca test results.
Anything below that should be recharged and tested with professional test equipment.
Input your battery s cca rating number into your tester.
1 cold cranking amps cca cold cranking amps cca is the recognized industry standard for rating a battery s performance.
Switch your battery tester to cca cold cranking amps mode.
Here are a few brief definitions of what your battery test is telling you about the health of your battery.
If the open circuit voltage drops below 12 4 volt the battery needs to be recharged.
What does your battery test result mean.
As the cca rating increases it indicates a higher powered battery.
The battery test for an agm or efb battery is more extensive as the demands on these special battery technologies are more complex.
Never confuse this rating with cranking amps ca a rating based on an easier test that produces inflated numbers.
Test and assessment of a start stop battery.
To test the cca capacity of a battery using a load tester the battery must have at least 70 to 100 state of charge.
This information can help you estimate the residual service life of your battery.
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.
Cold cranking amps is a rating applied to car batteries expressing how much electricity flows from them at 0 f.
Your battery s cca rating is probably written on its casing.
A state of charge test does not indicate whether your battery is good.
