The temperature outside affects the voltage of the battery.

Check car battery health with multimeter. Let the meter black probe make contact with the battery. Testing a battery with a multimeter is a simple process. Connect the multimeter to the positive and negative battery terminals.

First, set your voltmeter to 20 dc volts. The first thing to do is make sure you can access the two terminals on the top of the battery. How to check car battery with multimeter.

A multimeter is an electronic instrument that measures voltage, current and resistance. If the multimeter shows a reading relatively low than 15 volts, then the battery is in bad health. Using a multimeter to test a car battery.

Batteries are commonly located in the engine bay to one side of the engine, and often have a plastic cover which will unclip, lift off, or occasionally require the removal of a couple of bolts. Firstly set the multimeter reading to 15 volts and switch off the lights. You can use a multimeter to check if there is a leak on your car battery.

Each multimeter model is built for a certain amount of current, and the rating needs to be adequate to test your car battery. If you think your car battery has a low charge or it’s been a long time since you have replaced it, you should check its health.
