Black and Decker Cordless Drill Not Charging: Causes and Solutions

When your black and Decker cordless drill is not charging, there could be several potential causes. However, you need not fret as these causes have corresponding solutions that you can fix by yourself and let your tool resume its functionality.

Below are some of the elements you must consider when your Black and Decker cordless drill is not charging.

Unfavorable Temperature

It is recommended to store your Black and Decker cordless drill at room temperature for optimal performance. Storing the battery amid very high or low temperatures may therefore prevent the battery from charging. Additionally, prolonged use of the cordless drill while plugged into a power source may result in the battery overheating.

Consider checking whether the battery feels too warm or cold to confirm if this is the problem. Alternatively, check whether the charge light is flashing slowly, which acts as a warning sign to indicate that the surrounding temperature is unsuitable for charging. If that’s the case, detach the battery from the drill and store it at room temperature for it to cool down. Once the temperature is restored, reinstate your battery and try charging the drill again.

Defective Charger or Cables

In this case, examine the charger for any defects and check whether the cables are loose. Ensure you brush off any dust or debris on the charger or cables. Subsequently, detangle any twisted cables for ultimate results.

You can then test the charger using other batteries to confirm if it’s effective. Failure to charge another battery signifies that the charger is defective and it’s time to replace it.

Corroded Terminals

DIY equipment such as cordless drills are often stored in the garage, where anything goes. If you store your Black and Decker cordless drill in the garage, it is subject to corrosion and debris buildup, which may obstruct current flow, preventing the battery from charging.

If the terminals are corroded, you should see the charge indicator light flashing fast to indicate a poor connection between the drill’s battery and the charger. Therefore, it is advisable to wipe the battery’s contact terminals using a dry piece of cloth before attempting to charge it again. If the flashing persists, then the battery needs a replacement.

Empty or Faulty Battery

If you use the battery for a prolonged period without recharging it, an empty battery is likely to cause the problem. Over-discharging your Black and Decker cordless drill’s battery could also result in the battery not charging. If the battery falls below four volts, recharging it could be a hassle. During such instances, reviving the battery is the ultimate solution, rather than opting for a replacement battery, which could be costly.

How To Revive a Cordless Drill Battery That Won’t Charge

All you need to facilitate this process is a functional spare Black and Decker battery and two good conductors, preferably paper clips. Worry not if you don’t have a spare battery since a car battery works as well. With these items in place, follow the steps below to revive your cordless drill’s battery:

  1. Detach the battery that won’t charge from the cordless drill.
  2. Place the battery side to side with the functional one.
  3. Identify the positive and negative terminals of both batteries.
  4. Using a straightened paper clip, connect the positive terminal of the spare battery to that of your drill’s battery that won’t charge.
  5. Similarly, use another paper clip to connect the negative terminals of the two batteries.
  6. Wait for a few minutes for the battery to be jump-started, after which you can try charging the device again.

Since the drill’s battery was completely discharged, consider charging it for up to three hours to ensure it attains a full charge. If this fails to resolve the issue, the battery may be faulty, requiring a professional to fix it. Attempting to fix the battery by yourself could end up voiding the warranty. Therefore, the ultimate solution is to contact Black and Decker customer service.

How to Care For Black and Decker Cordless Drill Battery

The Black and Decker cordless drill often cost an arm and a leg, and having to replace it time and again could be a deal-breaker. That said, here are some of the recommended practices that extend the life of your Black and Decker cordless drill:

Charge the battery fully. This enhances optimal performance and helps prevent disruptions amid your DIY projects.

Use the battery regularly. Even when idle, cordless drills can use up their batteries and completely deplete them. Therefore, it is advisable to occasionally recharge the battery when not in use to prevent it from being depleted.

Restore the battery to its carrying case after use to prevent exposure to dust or liquids.

  • Store the drill’s battery in a cool, dry place to prevent corrosion of the contact terminals.
  • Use proper torque settings to extend the battery run time. Using a very high torque uses up the battery faster, thus compromising its runtime.
  • Avoid over-discharging the battery by ensuring the battery level does not go below four volts, as this often results in the battery not charging.
  • Always have an extra or spare drill battery. In this way, you can prevent inconveniences caused by constant battery depletion in the middle of your projects.
