Black and Decker 18v Battery Won’t Charge-Easy Solutions

The Black and decker 18v battery provides a power supply to the cordless tool, enabling it to function normally. Also, it stores power that keeps the tool functioning in power issues such as power blackout and power surge. Sometimes, the black and decker 18v battery may fail to charge due to many reasons.

For instance, the battery may fail to charge due to a damaged charger, dead battery, among others. However, it is easy to inspect and detect the cause that affects the battery charging system. The information below pinpoints the main reasons why black and decker batteries won’t charge and the possible ways of troubleshooting the problems.

Reasons why black and decker batteries won’t charge with possible solutionsBlack And Decker 18V Battery Won't Charge

Just like other battery models, the black and decker 28v battery requires some elements to function normally. The elements include; a well-functioning charger, power source, battery, and wiring cables. If any of these elements fail to work, the battery refuses to charge. There are several reasons why your black and decker 18v battery fails to respond to the charging system. The information below describes the main reasons your battery won’t charge with possible solutions.

  • Blown out battery chargerBlown out battery charger

A blown charger is a common reason that results in the battery not charging. Sometimes, the black and decker battery may fail to charge due to a faulty charger or a blown-out charger. Once the tool charger is damaged, power flowing from the power source to the battery fails to take place; thus the battery fails to respond to the charging system.

Also, broken battery charger wires affect the flow of power from the power source to the battery. First, inspect the condition of the charger cables. Carefully examine the wiring process and see if the terminals match correctly. If the wires are loose or disconnected, use a recommended tool such as a wire stripper to tighten them.

To detect the condition of the charger, try using a well-functioning charger that suits the battery charging system. If the battery begins charging, then the possibility of the charger blowing out is high. On the other hand, if it fails to charge the battery, consider inspecting other elements such as the battery itself, wires, and power supply source.

  • A dead batteryA dead battery

The main reason why the battery fails to charge is a result of a faulty or dead battery. For example, suppose the black and decker 18v battery is old. In that case, there is a high chance of the battery being dead, failing to respond to the charging system, and hibernating the battery for long discharges. Continuous discharging of the battery results in the battery dying.

In such circumstances, it is advisable to test your battery when not in use to prevent the occurrence of the hibernation process. Further, consider replacing the dead or faulty battery with a new one. While replacing the battery, ensure you buy a battery that suits your cordless tool and is of high quality. Also, contact an expert to help you choose and fix the new battery.

  • Damaged cordless tool charging portDamaged cordless tool charging port

A cordless tool charging port is essential in that it allows battery charging to take place. Sometimes, dirt and dust may accumulate in the charging port preventing power transfer from the power source to the battery.

Further, a distorted charging port can also hinder the battery’s transfer to the battery during the charging process. Also, charging port corrosion weakens the connection between the battery and the power source, thus preventing power transfer to the battery. However, the damaged charging port is fixable as long as you follow the recommended steps.

If there is an accumulation of dirt and dust in the charging port, consider using a vacuum cleaner to suck all dust from the port. Also, consider contacting skilled personnel to help you remove dust and dirt from the charging port using an appropriate tool.

  • Use of incorrect batteryUse of incorrect battery

Most people tend to interchange the cordless tool battery, especially when the battery fails to charge. Sometimes, a faulty battery that does not suit the cordless tool may fail to charge and function normally. If the black and decker 18v battery fails to charge, check the model of the battery if it suits your tool.

If the issue is due to the use of the wrong battery, consider purchasing the battery recommended by the manufacturer. Also, when interchanging batteries, ensure you have a complete understanding of the type of battery that suits your tool. Finally, if the problem persists, check the terminal connection of the battery and the tool. Ensure positive and negative terminals of the battery correctly match the terminals of the cordless device.

  • Damaged power supply source

People tend to forget to check the condition of power sources such as switches. Sometimes, the battery failing to charge is a result of a damaged or distorted power source. First, inspect the status of the switch and attempt to change the charging ports. If other power supply sources charge the battery, consider contacting a skilled electrician to help you fix or replace the switch.

Further, it is advisable to avoid touching electricity power supply sources with bare hands.

  • Power blackout

In most cases, power blackouts automatically affect the process of charging your battery. It is impossible to charge the black and decker battery without any power supply source. Consider having a backup power supply source such as a generator, solar panel, or any other recommended power backup source to fix power blackout issues.

  • Wrong battery charger indicator lightWrong battery charger indicator light

Some electrical devices detect charging issues and display an indicator light notifying you that the battery is not charging. But, the battery might be charging with the indicator light on. First, inspect the device if it is charging. If the problem persists, consider replacing the battery but, if you know how to troubleshoot the indicator light, attempt fixing the indicator by using the recommended steps.

  • Use of the wrong charger

Chargers differ from each other depending on the type of tool. Using a wrong charger that does not suit your tool’s battery automatically prevents energy transfer from the power source to the battery. Such issues are easy to fix and do not require complex procedures.

The only possible solution to fixing the wrong charger problem is using the correct charger that suits your tool. Therefore, it is advisable to avoid using the faulty charger.

  • Battery failing to charge with flashing red light onBattery failing to charge with flashing red light on

Batteries sense the existence of too much heat or too much cold. Some batteries fail to function when they are too hot or too cold. To troubleshoot such problems, disconnect the device from the power source. Remove the battery and let it sit for a couple of minutes until it completely cools down if it is hot. Reinstall the battery and test if it is charging correctly.

If the battery is too cold, consider increasing the room’s temperature with a thermostat and leave the battery for some time to heat for approximately forty to fifty minutes. Try charging the battery, and if the problem persists, consider replacing the battery with a new

Final Talk

Black and decker batteries last for approximately four years if well maintained. However, despite the regular maintenance, the battery may fail to charge at some point. If your black and decker battery fails to charge, check all parts and try troubleshooting them according to the information above.

Finally, follow the manufacturer’s instructions when handling the battery. Moreover, it is advisable to regularly service and uses your battery to prevent the battery from hibernating. Also, consider contacting skilled personnel if the problem persists.
