How to Test Your Car’s Battery

It’s recommended to check your car’s battery after each winter and summer. These season’s extreme temperatures create extra work for the battery and entire charging system. Keeping up on routine maintenance helps ensure you don’t get stranded somewhere. If the battery appears slow to start, check the cells’ fluid levels. Top them off with distilled water if low. From there, you can check its voltage.

With a voltmeter, simply look for a minimum of 12.6 volts on the fully-charged battery. When you test it while the engine’s running, it should measure between 13.7 and 14.7. If you don’t have a voltmeter with you, start the engine and turn on the headlights. They should be consistently bright, whether or not you rev the engine. If they appear dim, or their brightness fluctuates as you press the gas, that’s a sign that the system isn’t charging as it should.
