How do you test a battery?

A load test measures the battery's power when it's in use. Higher-end multimeters have 2 load settings, 1.5V and 9V. For a AA, AAA, C, or D battery, set the voltage dial to 1.5V. Set the voltage to 9V for a 9v battery. Hold the black probe to the negative end of the battery and the red probe to the positive end to test the battery's milliamps.

How do I know if my car battery is working?

Alternatively, use a multimeter to test your battery by turning the knob to 20 on the “DCV” or “V” side.

How do you test a start-stop battery?

When testing a start-stop battery, not only the state of charge (also known as the “SOC”), but also the state of health (“SOH”) of the battery are important. While the SOC can be simply determined with a voltage measurement, a complex test procedure is required to test the SOH, in order to make a reliable statement about the state of the battery.

How do you know if a 9 volt battery is working?

Touch the red probe to the battery’s positive terminal and the black probe to its negative terminal.
