Whether you’re a seasoned craftsman or a DIY enthusiast, understanding and addressing these common charging issues can ensure that your cordless drill remains a reliable partner in your endeavors. So, let’s unravel the mysteries behind a non-charging Black and Decker cordless drill

Black and Decker Cordless Drill Battery Not Charging

If your Black and Decker cordless drill isn’t charging, there could be several reasons behind it. Here are some common causes and solutions:

Faulty Battery:

Rechargeable batteries have a limited lifespan and eventually lose their ability to hold a charge. If your battery is several years old or has been heavily used, it may need to be replaced. Also, physical damage to the battery, such as cracks or leaks, can hinder its ability to charge. Inspect the battery for any signs of damage and replace it if necessary.

Charger Issues

The charger itself might be defective or damaged. Test it with another compatible device to determine if it’s working properly. If not, replace the charger with a new one.  Ensure that you’re using the correct charger for your specific Black and Decker drill model. Using an incompatible charger can lead to charging problems.

Dirty Contacts

Dust, dirt, or corrosion on the battery contacts can create a barrier between the battery and the charger, preventing proper charging. Clean the contacts thoroughly with a dry cloth or a soft brush to ensure good contact.


Charging lithium-ion batteries in extreme temperatures (too hot or too cold) can reduce their efficiency and lead to charging issues. Charge the battery in a more moderate environment to avoid temperature-related problems.

Batteries, including those found in cordless drills, operate optimally within a specific temperature range. Most cordless drills use lithium-ion (Li-ion) batteries due to their high energy density and lack of memory effect. However, extreme temperatures, whether too hot or too cold, can have adverse effects on battery chemistry and performance.

High temperatures accelerate the chemical reactions within the battery, causing it to degrade faster over time. This degradation reduces the battery’s overall capacity and lifespan. In addition, excessive heat can lead to safety hazards such as thermal runaway, where the battery overheats uncontrollably and may catch fire or explode. Lithium-ion batteries have built-in safety mechanisms to mitigate these risks, including temperature sensors that may suspend charging if the battery temperature exceeds safe limits. At high temperatures, the internal resistance of the battery increases, reducing its ability to accept a charge efficiently. This can prolong charging times and lead to incomplete or inefficient charging cycles.

On the other hand, cold temperatures can cause the chemical reactions within the battery to slow down, reducing its capacity temporarily. This means the battery may not deliver as much power as expected, resulting in decreased runtime during use.

Increased Internal Resistance

Just like with high temperatures, low temperatures can increase the internal resistance of the battery, making it less efficient at accepting and delivering a charge. This can lead to longer charging times and reduced overall performance.

Risk of Damage

In extreme cold, the electrolyte inside the battery may freeze, potentially causing irreversible damage to the battery’s internal components. This can result in permanent capacity loss or even render the battery unusable.


Some cordless drills have built-in temperature sensors that halt the charging process if the battery becomes too hot. Allow the battery to cool down before attempting to charge it again to prevent overheating.

Faulty Wiring

When dealing with a Black and Decker cordless drill that won’t charge, faulty wiring is another potential culprit that warrants attention. Here’s a more detailed look into this issue:

Examine both the charger and the drill for any visible signs of damage to the wiring. Look for frayed wires, exposed conductors, or any other indications of wear and tear. Pay close attention to areas where the wiring is exposed or where it connects to other components such as the battery terminals or the charging port.

Causes of Faulty Wiring:

  • Physical Damage: Over time, the wiring in a cordless drill can become damaged due to regular use, movement, or accidental impacts. This damage can compromise the integrity of the wiring and hinder the flow of electricity.
  • Moisture or Corrosion: Exposure to moisture or corrosive substances can corrode the wiring, leading to degradation and poor conductivity. This is particularly common in humid environments or if the drill is used in outdoor or damp conditions.
  • Overheating: Excessive heat generated during prolonged use of the drill can cause the insulation around the wiring to degrade. This can expose the conductors and increase the risk of short circuits or electrical faults.

 Consequences of Faulty Wiring:

  • Intermittent Charging: Faulty wiring can result in intermittent charging, where the drill may charge sporadically or only when the wiring makes partial contact.
  • Incomplete Charging: If the wiring is damaged or corroded, it may impede the flow of electricity, resulting in incomplete charging cycles. This can lead to reduced battery capacity and shorter runtime during use.
  • Safety Hazards: Damaged wiring poses a safety risk, as it increases the likelihood of electrical shorts, sparks, or even electrical fires. It’s essential to address any wiring issues promptly to mitigate these risks.

Solutions for Faulty Wiring:

  • Repair or Replacement: If you identify any damaged wiring, it’s crucial to repair or replace it to restore proper functionality. This may involve soldering damaged wires, replacing connectors, or installing new wiring harnesses.
  • Professional Assessment: If you’re unsure about how to repair the wiring yourself, consider seeking assistance from a qualified technician or contacting Black and Decker’s customer support for guidance.
  • Preventive Maintenance: To prevent future issues with wiring, perform regular inspections of your cordless drill and ensure that all wiring connections are secure and free from damage. Avoid exposing the drill to excessive moisture or heat, and store it in a dry, cool environment when not in use.

Faulty wiring is a potential cause of charging problems in a Black and Decker cordless drill, and it’s essential to address this issue promptly to ensure safe and reliable operation. By inspecting for damage, identifying the root causes of wiring faults, and implementing appropriate solutions, you can resolve charging issues and prolong the lifespan of your cordless drill. Remember to prioritize safety when working with electrical components and seek professional assistance if needed.

Software Reset

Some cordless drills have built-in safety features that can cause charging issues if they detect abnormal conditions. Perform a soft reset by removing the battery, waiting for a few minutes, and then reinserting it to reset the drill’s software.

Manufacturer Support

If none of the troubleshooting steps resolve the issue, contact Black and Decker customer support for further assistance. They can provide guidance or direct you to a certified service center for professional repair.


A malfunctioning Black and Decker cordless drill can disrupt your projects and cause frustration.
