Troubleshoot a Broken Battery Charger Troubleshoot a Broken Battery Charger
If your battery will not take a charge, it may be because your charger is not working. When you have broken equipment, you should test it to see if you can fix it or if you must replace it instead. There are a few tips you can follow when testing your battery charger for problems.
Step 1 - Check Your Outlets
There are three ways to check the outlets that power your chargers. First, plug another device into it and see if it works properly. You can also plug your charger into another outlet and see if it will charge your battery. Finally, check any indicators on the charger — like light or sound — to make sure it is getting electricity.
Step 2 - Check the Battery
Sometimes it may not be your charger that is broken, and rather the battery. You can determine this two ways. Try charging your battery in another charger and see if it will charge. If it will, your charger may be the problem. You can also try charging a different battery with your charger. If it works, it is your initial battery that doesn't work.
Step 3 - Check the Charger
Look at your charger and see if there are any parts of it that may be broken or warped. Look at the prongs that connect to your outlets as well as the piece that will actually charge your battery. Make sure that nothing is bent, broken or missing, and that it responds properly to your touch.
Also check any metal parts of your charger for corrosion or rust, which would be a sign of moisture. If your charger has come into contact with water or another liquid, there may have been a short caused inside your charger that may not allow the charger to work.
You will also want to check any wiring on your charger to make sure that the wires are connected and not cut or rusted.
Step 4 - Use a Voltmeter
You can use a voltmeter by connecting the device to your charger. Touch the contacts of the charger with the probes and make sure that you get a reading. If you do not get a reading, switch the probes and try again. If you still do not get a reading, your charger may be dead.
Step 5 - Clean Your Charger
Cleaning your charger should be a last resort because it could cause damage to a working charger. You can try cleaning your charger by cleaning the contacts, or the metal strips that connect to your device. Do this by cleaning it with a little rubbing alcohol and a cotton swab. You can remove corrosion with a fine emery board. Make sure that you let the charger sit for a while before plugging it in. This will give the rubbing alcohol a chance to dry.
By figuring out the problem with your charger, you will be able to determine if the charger can be fixed or if it must be replaced.
