How does a battery pass a load test?
To pass a load test, the battery must maintain 9.6 volts at 15 seconds when tested at one-half the CCA rating and 70°F (or above). This test must be done with a true load (carbon pile) and not one of the hand-held testers that work off a conductance algorithm. The test must be run with the battery in a high state of charge.
Why do you need a qualification test for a battery?
Battery specifications should always include the test conditions to avoid ambiguity. Qualification testing is designed to determine whether a cell or battery is fit for the purpose for which it was intended before it is approved for use in the product. This is particularly important if the cell is to be used in a “mission critical” application.
What should I look for in a battery test?
If you’ve been experiencing problems with your battery system and the headlight test checks out okay, you should check whether or not the battery is holding a charge, or if something on the vehicle is discharging it. How Do You Perform A Load Test?
When to go to Advance Auto Parts for battery test?
If the battery voltage drops below 9.6 volts, this is an indicator of a weak battery. If you suspect your battery is failing, stop by your local Advance Auto Parts. Advance offers quick curbside testing without you needing to leave your vehicle.

What’s the best way to test a battery?
Disable either the fuel or ignition system — whichever is easiest on your vehicle. This is necessary because the test is dependent on the vehicle cranking, but not starting. Place the positive multimeter lead on the positive battery terminal and the negative lead on the negative terminal.
