Why Is My Car Battery Not Charging

If your car battery is not charging there are a few things that could be causing the problem. First check the battery itself to make sure that the terminals are clean and free of corrosion. If the terminals are corroded you can clean them with a wire brush or a solution of baking soda and water.

Next check the alternator to see if it is working properly. The alternator is what charges the battery so if it is not working correctly the battery will not charge. You can test the alternator by starting the car and then measuring the voltage at the battery terminals with a voltmeter. If the voltage is low the alternator is not working properly.

If the battery and alternator are both in good condition the problem may be with the car’s electrical system. A loose or damaged wire may be preventing the battery from charging. You can check the wiring by using a voltmeter to test for continuity.

If you can’t find the source of the problem it is best to take your car to a mechanic or an auto parts store to have it diagnosed. They will be able to test the battery alternator and electrical system to find the cause of the problem and get your car back on the road.
