Black and Decker battery chargers failing to work is a normal problem that the batteries and chargers experience which can be a result of either of the devices. The issue with the Black and Decker battery charger is the cordless power tools which can be loose or so. There are several ways you can fix the issue so that you do not need to worry about it.
There are several reasons why the black and Decker battery charger does not work. It can happen due to the following reasons: issues with the charging cable, the charger can be defective, faulty battery, defective charging port and issues with the battery and charger terminals which can be dirty or bent.
Below are the reasons for their descriptions and I will provide the ways of fixing the issues with both the charger and the battery. Thereafter are the frequently asked questions and lastly the conclusion
Why does the Black and Decker battery charger fail to work?
Several reasons can make the Black and Decker battery charger fail to work. Below are some of the reasons:
- Defective charger
A defective charger is a common problem that the chargers can face and makes them fail to work with the Black and Decker battery. Identifying a defective charger is easy since you can check on its appearance. What causes the damages with the charger are maybe high temperatures due to heat exposure to it, overcharging, short-circuiting and dust at the endpoint. Therefore, consider checking the charger by opening it inside it and cleaning it frequently.
- Faulty charging port
The battery’s charging port can be faulty that makes the charger fail to transmit power from the charger to the battery and you can think that the charger is the one with issues. A charging port that is dirty or has faults cannot charge any battery since the charging ports are made of copper material which cannot supply current with faults. When the ports are corroded, they can also fail to transmit power since the rust interrupts the flow of electricity.
- Faulty charging cables
A charging cable is a mode of transmitting electricity from the charger to the battery that if it is faulty the battery will not get any power. The cables can be bent, twisted or stretched and can interrupt the flow of current when charging the battery. When the cable has issues, it means that the wires that are inside are ones with issues that you need to check to fix them.
- Defective plates and fuse
The plates and fuses that are defective are challenging with the charger that you need a technician to help fix the issue. When the fuse is defective, there could be issues with the nickel parts that are not easy to understand unless you are professional. The only thing you can check with the plates and fuse is if there are any dirty particles with them or dust that you can wipe with a cleaning detergent and a piece of cloth or cotton wool.
- Dead battery
If the battery is dead, that shows they cannot store any power with them and they cannot perform any activity with the related devices. Remember batteries have their life cycle that if the cycle is over the battery will receive a charger from the charger and you will feel like the charger is not working. Therefore you need to know the life cycle of the battery you are using so that when it fails to work, have in mind that it is dead and you need to replace it with a new one. With the case of the Black and Decker battery, the lifecycle is about four years. S
- Poor battery memory
Battery memory is the ability of the battery to hold a charge that when the battery becomes defective, it will fail to hold charge for long which is that they are poor. The battery’s memory becomes poor as a result of charging the battery most frequently and sometimes putting it on charge for a long time. Sometimes the battery experiences the problem since you always charge it when it still has power. Therefore, consider charging the battery when it is zero.
- Over discharging of the battery
When you discharge the battery most of the time, you are making a big mistake since it weakens the battery power and the battery will fail to work. The problem can reduce the life cycle of the battery. Remembering when you charge it more frequently without discharging also causes the problem.
What shows that the Black and Decker battery charger is not working?
To identify if the battery charger is working or not, consider checking the flashing light that is at the Black and Decker battery. The light varies with different states and it will also change when the battery is fully charged. Therefore, when there is no flashing light with the charger, it means that the charger or the battery is not working and if there is a flashing light but the chargers’ light is not changing when the battery is full it is also not working.
Check on the chargers’ voltage using a voltmeter so that you can know the state of the charger. After knowing the signs of a faulty Black and Decker battery charger you can move on and fix the problem with it. If the issue is with the charger or the battery consider replacing it with another one since dead batteries do not require repair.
How to troubleshoot a black and Decker battery charger that is not working
After identifying the cause of the black and Decker battery charger that is making them not working, continue with the process of fixing the issue. Below are some of the methods you will use for the troubleshooting process.
| Technique | Function | Essential products |
| Replace the battery chargers’ fuse | To fix a new fuse | Check Amazon for the best fuse |
| Boost a dead battery. | To increase the life span | Check Amazon for the best battery |
| Clean the battery and charger terminals. | To remove dirt on the terminals | |
| Replace the faulty parts and cables. | To fix new parts | Check Amazon for the best cables |
1. Replace the battery chargers’ fuse
The fuses in the battery charger work by preventing the battery from electric short circuits and other electrical problems. When you check the fuses and see that they are faulty, consider replacing them with new fuses and the battery or the charger will work properly.
Choose to use a fuse that is compatible with both the battery and the charger by checking the model of the battery and charger before purchasing the fuse. To replace the fuse, ensure you have the voltmeter, multimeter and Phillips screwdriver for the replacement process. Before fixing the new fuse, check the voltages of both the battery and charger then fix the fuse.
2. Boost a dead battery
When you have a dead battery but the life cycle is still there, you can boost it. Boosting a dead battery involves using a direct current power supply or using a different battery.
- Boosting a dead battery with a direct current power supply
Using direct current to boost dead batteries is like jump-starting the car batteries. Therefore, the only thing you need to do is ensure the voltages of the direct current power supply are the same as that of the battery. After that, connect the positive terminals of the battery to the positive terminals of the power supply and connect the negative terminals with the same step as the positive terminals. You can then jump-start the battery by plugging in the power source. Give the battery-less time to jump-start to reduce overheating.
- Boosting the dead battery using a different battery
Using a different battery to boost the dead battery is a simple task that is just the same as using the direct current power supply. What you need with this method is to ensure the battery you are using is charged fully and check the voltages so that it is the same as the one with the dead battery.
Using a wire, connect the dead battery with the new battery maintaining the positive terminal with the positive terminal. Do the same with the negative terminal of the batteries. After connecting the two batteries, give them time for the boosting process and check if the dead battery is charging.
3. Clean the battery and charger terminals
Consider cleaning the battery and chargers terminals to reduce some of the issues related to it.
4. Replace the faulty parts and cables
If you have faulty cables and parts of both the charger and cables, consider removing them and replacing them for the charger and battery to work well.
Conclusion
After getting that the Black and Decker battery charger is not working, check on the methods to repair the faulty parts to fix it or replace the battery if it is dead. Follow the guidelines of using the battery and charger to avoid some problems with them.
The guide contains the reasons why the battery charger has some issues with it and how to fix it. There is also a way you can use to identify if the charger is faulty or not.
