How to Test Your Car's Battery with a Voltmeter


To test the battery in your vehicle, the voltmeter can give an accurate reading about the charging power left in the cells.

To test your battery, be sure you are wearing safety glasses and a good pair of work gloves. The car lights and the engine should be off before you check the battery.

The voltmeter has a red and black cable. Red is attached first to the positive battery terminal, the black cable then goes on the negative terminal.

Once the two connections are secure, you can load test the battery. The voltmeter will show a reading of 12.4 if the battery is strong. When the meter comes back with reading at or under 12.2, then the battery is experiencing issues and it may need to be replaced before failing.

Get your car to Basic Auto Sales so we can check the charging power in your car battery and replace if needed.
