How to check car battery with multimeter. The first test with your multimeter will measure DC voltage, indicated with a solid line and a dashed line above a letter V. Set the dial to 20, which will allow you to accurately measure between 0-20 Volts. Touch the red probe to the positive terminal, and the black probe to the negative terminal.
Load test a car battery using a multimeter. Connect the multimeter probes to the car battery. Set voltmeter reading to auto-detect or 20 volts. Note battery voltage with the engine off. Crank up the car and in the meantime watch the volta drop on the multimeter. (It is ok if the car doesn’t start.)
Switch your battery tester to voltage testing mode to determine the battery’s state of charge. Most car batteries are called “12-volt,” but actual voltage depends on the state of the charge. This test can be performed with a simple voltmeter or multimeter, but a battery tester will determine this as well.
There’s also another way to check the alternator manually. It is for those who do not have a multimeter nor the knowledge of using one.
