Car Battery Testing Safely with the Voltmeter

Being able to test the battery inside your car using the voltmeter is simple, that is if you are using the right safety equipment.

Shut off the car engine and the lights on the car, then open the hood and make your way to the battery compartment.

The battery terminals will be marked plus and minus. The voltmeter has a red cable that is positive and connects to the plus side. The voltmeter also has a black cable that is negative and connects to the minus side.

The reading on the voltmeter is going to be at or above the 12.4 mark if you have nothing to worry about concerning the battery. There is reason to be concerned when you see the meter reading at or below the 12.2 mark, don't put off having it looked at.

Don't hesitate in coming to Ed Howard Mazda to get the car charging system checked today.
