How do you test a battery’s voltage with a multimeter?

A multimeter is the perfect tool to test the voltage stored in your car’s battery while at rest. The device measures the voltage available based on the amount of current traveling from one location to another. In the case of the multimeter, the current is traveling from the positive pole to the negative pole.

When using the multimeter to measure the amount of voltage stored in your battery, touch the red probe to the positive pole of your battery and the black probe to the negative pole, establishing a connection from one side of the battery to the other. Adjust your multimeter to 20 under “V” for voltage, so that it will accurately measure the voltage in your battery from zero to 20 volts. If the reading is below 12.2 volts, your battery is dead.
