Do you remember when you last had your battery serviced? The summer heat and winter cold take a big toll on your car’s battery, which could wind up leaving you stranded. If it’s been a while, or it has been a rough season for your battery, now is the time to test it yourself or bring your car into Pep Boys for a free battery test.

To determine if your battery is fully charged, you will need to measure your battery’s state of charge with a voltmeter. You can use an analog or digital voltmeter, but a digital meter will give you an easier-to-see, more accurate reading. If you are a do-it-yourselfer, remember to always wear a pair of rubber gloves and goggles whenever you service your battery. This will protect your hands and eyes from acid.

Follow these steps to test your battery:
  1. Before you begin testing, make sure the ignition key and all of your vehicle’s lights are off.
  2. Connect the red or positive voltmeter test lead to your battery’s positive terminal.
  3. Then, connect the black or negative voltmeter test lead to your battery’s negative terminal.
  4. Compare your reading to this chart:
  5. Always remove the negative terminal first. If the battery terminals do not come off easily, use a battery terminal puller to remove them. Do not use a screwdriver to pry the terminals off because it can break the internal connections of the battery post.
  6. Take your battery terminal cleaning tool, which should have different extensions for different sized terminals, and use it to clean off the terminals and posts. Also, use a quality battery cleaning solution, which is available at your local Pep Boys.
