One of the components you should check is your car’s battery. The battery is essential to your vehicle, but how do you check your car battery voltage? We have made this helpful guide to walk you through how to safely do just that.

Getting the Right Equipment to Check Your Battery Voltage

Before you can check the voltage of your car’s battery, you’ll need to make sure you have the right equipment to do so. A voltmeter is a tool used specifically to test and read the battery’s voltage. If you don’t have a voltmeter, you can purchase one at any local store that sells automotive equipment.

Attach the Voltmeter to Your Battery

You’ll have two ends to your voltmeter: one positive and one negative. Most of the time, red signifies positive and black represents negative. You’ll want to attach each end to the corresponding terminal on your vehicle’s battery

Getting a Reading

When the voltmeter is correctly hooked up to the battery, you can then observe the digital reading displayed on the device.

A battery that is in good condition will give a reading between 12.4 and 12.7 volts.

What to Do If My Car’s Battery Voltage Is Low?

If your battery falls below that range, you’ll need to recharge the battery. This can be done a few ways, most commonly with the car’s alternator or a portable battery charger.

If you don’t have a portable charger and want to use the alternator to recharge, you’ll first want to jump your battery. Then, you should drive it around for at least 20 minutes at speeds of 40 MPH or faster.

After that, you can retest it by leaving the car idling and getting a new reading on the voltage. This time, you’ll want it between 13.5 and 14.5 volts. If it is lower than that, there may be an issue with the connection or the alternator itself.
