However, even before we start thinking about your options, you should be sure that your charger is the problem. In this guide, I will show you the steps you can follow to troubleshoot the battery charger and determine the root cause of the problem.

Step 1: Check your power outlets

Before you declare the battery charger faulty, ensure that your electricity supply systems are all functioning. Start by checking your wall outlets to figure out if they are functioning accordingly. You have three options when it comes to checking the wall outlet. Start by trying the charger on a different outlet. You may also try other devices on your outlet to see if it works. Finally, you can check the indicators on your battery charger such as lights to see if they are functioning. If the outlet is the problem, your charger should work when moved to a different outlet.

Step 2 - Check the Battery

In some cases, you may be busy trying to fix your charger, when it is the battery that needs fixing. The second step in troubleshooting your charger is testing the battery. To determine if the problem is with your charger, try charging the battery with a different charger. If the battery charges well chances are that the issue is with your charger. You may also use your charger on a different battery. If our charger does not work well on a different battery, chances are that it has a problem.


Step 3 - Check the Charger hardware

The next step should be observing the charger for any physical signs of breakage or damage. Look at the charger to see if there are any parts that are broken. Ensure that there are no parts that are bent, broken, or missing. If there is rust on any part of the charger, have the rust washed by dipping a rag in alcohol and using it to clean the rust. If the charger has clear breakages that could be causing the problem, fix them. If it does not show any signs of breakages or rusting, move on to the next step.

Step 4 - Use a voltmeter to test your charger

The next option would be using a voltmeter to test the charger. A voltmeter is a device used to detect the charge passing through any electronic device. To test your charger, connect it to a power source and touch the contacts of the charger with the voltmeter probes to see if you get a reading. If there is no reading, switch the robes and try again. If you still do not get a reading, chances are that your battery is dead.
