Troubleshooting black and decker battery charger

Your battery is too low of a voltage, but when you want to start your drill, no power. This problem is hectic and you won’t like it. Have a look at the following possible reasons and solutions for the problem.

1. Wrong charge signal light

With some electrical devices, when there is a fault, the indicator lights might be problematic. I say so because your battery could be charging, but not the indicator. So try to use it on the device and see the readings. There could be other issues because it is abnormal for display lights to stop working.

Buying another charger for your black and decker can be the best solution. But, if you have the skills to replace the light, go on because it’s also one of the ways to fix the problem, though quite technical. Before attempting this, you need to confirm whether the product is still under the warranty or not.

Black and Decker Battery Charger Problem

2. Corroded or dirty charging connection

Dirt and corrosion on the charger contacts and the battery may prevent smooth electrical flow. Fixing this issue is quite simple, but it needs some skills to access the connector terminals:

  1. Disconnect the charger before doing anything for your safety
  2. Use wire wool or a small screwdriver to scrape out the corrosions from the terminals
  3. You are also allowed to apply contact cleaner on the terminals (spray) if accessing them is challenging.
  4. Once fully cleaned, plug the charger again and observe the results.

3. Bad electrical outlet

If your charger doesn’t display any light, you have to plug it into another outlet. This situation occurs rarely, but it’s not known for outlets to have malfunctioned.

4. Battery is faulty or dead

Your battery might be the one problem and not the charger. With a dead battery, you will think the charger is faulty for the first time, but you need to be cautious and check the battery status. If the battery doesn’t respond to charging, probably the charger won’t do anything.

A battery with many years in the service life won’t be changed easily.

5.  Connection problem

Have you connected the charger to the battery correctly or not? If there are worn-out wires, then the charger won’t work. You should therefore have to check or inspect and make sure the chuck and battery wiring is properly connected. There should be no improper or loose wire connection. Yes, it’s therefore advisable to check the wiring condition and ensure they aren’t loose.

6. Faulty charger cable

To determine that the charger line is faulty, try using a different one to be sure about this problem. The cord of the battery charger might be worn out, hindering the passage of light. Using a new or just a different charger will help you determine and fix this issue once and for all.

7. Blown fuse

Fuse plays an important role in any charger to regulate the amount of electricity required by the appliance or battery. But, once this component is blown, there will be a power shortage or overpower. With such a situation, believe me, the battery charger won’t operate normally.

You also need to understand that a battery charger with a worn-out fuse, means that the circuit is incomplete. And, there will be no power passage. Fuse replacement can be a robust solution even, but some experts recommend buying a new charger. I say so because such misbehaviors with a battery charger can be an indicator of it getting out of service sooner.

You should always be on the look and ensure the charger’s fuse is okay for maximum and normal performance.

8. The charger is not plugged in

Maybe you are struggling and worried about this issue yet you haven’t plugged in your charger. Properly plugged in the battery charger implies that there will be enough electricity passage and vice versa. You should therefore inspect and confirm the charge is plugged in correctly for enough electricity flow in the battery.

This problem is overlooked by many people but it’s a serious one and happens often. At least you now know what it means to partial cord connection or plug in; carelessly or loosely connected batteries will result in low voltage flow.

9. Too cold or too hot air temperature

After long use of your machine, you should not plug in the charger immediately. The drill overheats due to overuse, so allowing it to cool is the best solution. If the charger doesn’t work, disconnect it and then connect again.

On the other hand, a too-cold environment, especially in cold winters can make your battery unreactive to charging. Too cold surrounding also tends to affect the charging normalcy. We recommend changing the environment; try to locate it two feet above the ground.
