An oft-overlooked aspect of maintaining your car is testing your car battery. It should be done twice a year so you know what condition your battery is in and you aren’t experiencing any unexpected battery failures when it matters the most. Our Canfield service center is staffed with certified technicians that can perform battery tests for you, but you can easily do it at home yourself to save time.

How Many Volts Should A Battery Have?

If you don’t have a multimeter, it might be a good investment to make so you can do easy battery tests yourself and know exactly how many volts are in your battery. Fully charged automotive batteries should measure at 12.6 volts or above, and when the engine is running, this number should jump from 13.67 to 14.7 volts.

The easiest way to perform a test without a multimeter is to start your car and turn on the headlights. If they are dim, that indicates that the lights are running off the battery and that little or no charge is being produced by the alternator. If you rev the engine and the lights get brighter, it means the alternator is working, but isn’t producing enough charge at idle ot keep the battery properly charged. If this is the case, Canfield drivers should schedule a service appointment to have a professional take a look at it.

If the lights have normal brightness and stay at a consistent level when the engine is revved, your charging system is more than likely functioning normally. If you’ve been experiencing problems with your battery system but it passes the headlight test, you should ask a technician whether or not the battery is holding a charge.
