If your device isn’t charging as quickly as it used to, or not charging at all, it might be time to test your battery charger. You can test your charger by plugging it into a working outlet and using a multimeter to test the voltage. If the voltage is below the manufacturer’s specified range, then your charger is not working properly and you’ll need to replace it.

So, how to test a battery charger?

To test a battery charger, connect the charger to the battery and turn it on. If the charger is working properly, the indicator light will turn on and the battery will start charging.

Let’s dig into it and see what’s inside.

step by step procedure for Testing A Battery Charger.

If you are unsure whether your battery charger is working properly, there is an easy way to check. Running a test on your battery charger is a simple process.

Step-1: Insert your charger into an outlet. Pack out any batteries that have been charging right on the charger.

Step-2: Turn the voltmeter unit’s power on. Make sure its fuse is intact and the power plug is properly attached to both the voltmeter and the meter’s master receptacle. Plug the test probes into their respective sockets within the voltmeter according to the unit’s instructions. Put the selector switch on the highest level for DC Volt or whatever is recommended in the meter’s requirements.

Step-3: Connect a battery or battery pack that is appropriate to the battery charger. Check that the battery has no issues and never leaks fluid. Touch the positive end of the battery with the red probe. Place the black probe on the negative terminal of the battery.

Step-4: Look at the readout on the voltmeter and observe the pointer. If it is on the left side, or near the negative side, switch the battery test probes. If it is on the right side, it will show that the battery pack is getting some charge. Where it indicates the meter is a function of how much charge is received.

Step-5: Check the battery charger to see how much energy it is able to deliveroff, while you continue to receive a negative reading from the batteries. A negative reading indicates that your battery is bad, so you should replace it. If the charger has enough power flowing through it, there is a good chance that the batteries are bad and will not hold a charge.

How Do I Know If My Battery Charger Is Working?

If you’re like most people, you probably don’t give your battery charger a second thought – until it stops working. Then you’re stuck with a dead battery and a lot of frustration. So how can you tell if your battery charger is working properly?

The first thing to do is to check the output voltage of the charger. Most battery chargers are rated for a specific voltage, so you’ll need to check that the charger is outputting the correct voltage. To do this, connect the battery to the charger and turn on the charger. The meter should read near or equal to the battery’s rated voltage. If it doesn’t, the charger fails.
