What to Know Before Testing
If you are going to test the battery yourself, then make sure you are properly equipped. You will need to be wearing rubber gloves and have on goggles for protection from acid. It is also required to have a voltmeter, so you can see how much charge is in the battery. We recommend picking a digital voltmeter for a precise reading. You will also need a battery cleaning solution for the end of your test.
Follow these steps in the order below to find out about your vehicle’s battery:
- To test the battery charge you will need to have the ignition off and all of the lights turned off.
- Find the positive voltmeter connector (it should be a red color) and connect it to the positive terminal on the battery.
- Do the same thing for the negative connector (it should be a black color) and attach it to the negative terminal on the battery.
- You want to see that your charging range is between 12.6+ to 12.4+ or 100% to 75%. Anything below these numbers are bad.
- Now that you have results, you should take off the negative terminal first. If you are having trouble taking it off, then use a battery terminal puller—do not under any circumstances use a screwdriver or attempt to pry the terminals.
- With a battery terminal cleaning tool and some of the solution, clean the terminals and post for an uninterrupted connection.
