If you think that your car's battery could need to be replaced, there are a few ways that it can be tested. One is to take your car to Land Rover Cape Fear so that someone can test it for you with a multimeter. If you're at home, you'll want to start by turning off your ignition. Accessories that might be on should be turned off as well. You can then use your own multimeter that you can purchase or rent at most auto parts stores.
Turn on your headlights without turning the ignition. Next, you want to start your car to see if your headlights dim, especially after turning on various accessories like your radio or air. If you notice that your headlights are dimming while driving in Wilmington, NC, then this could be an indication that your battery needs to be replaced.
You can also check the posts on your battery. If they are corroded, then it could be because the battery is old or beginning to leak fluid. You can clean the posts to see if this helps the power from the battery.
