If you’re experiencing trouble charging your Dewalt lithium-ion battery, don’t worry - there’s a simple fix that can help you get it working again. In this article, we’ll show you how to reset your battery so that it can start taking a charge once more. Follow these steps carefully to bring your battery back to life.

What Causes a Lithium Ion Battery to Stop Charging?

Sometimes, lithium-ion batteries can become completely depleted, causing them to malfunction and refuse to charge. This often happens when the battery is left unused for an extended period or when it is drained completely. When this occurs, the battery needs to be reset in order to begin accepting a charge again. Think of it like a golf cart; if you completely drain the batteries and don’t charge them for several days, you’ll need to charge each cell individually before the golf cart can function properly again.

The Materials You’ll Need

Before we start the reset process, gather the following materials:

  1. A fully charged battery - This will be used to provide a small amount of charge to the depleted battery.
  2. Speaker wire - You’ll need a couple of pieces to create the connection between the good battery and the one that won’t charge.

Step-by-Step Guide to Resetting a Dewalt Lithium Ion Battery

Follow these steps to reset your Dewalt lithium-ion battery:

  1. Identify the charging ports - On both the good and bad batteries, locate the charging ports. You’ll notice that each port has a positive (+) and negative (-) symbol.

  2. Connect the batteries - Take a piece of speaker wire and connect the positive (+) terminal of the good battery to the positive (+) terminal of the bad battery. Then, take another piece of speaker wire and connect the negative (-) terminal of the good battery to the negative (-) terminal of the bad battery. Be cautious while working with electricity to avoid any shocks.

  3. Transfer power - Hold the connection for a few seconds to allow the power to transfer from the good battery to the depleted one. This process will provide enough energy for the charger to detect the battery and initiate the charging process.

  4. Check for progress - Disconnect the wires and check if the battery is now recognized by the charger. If the battery still doesn’t show any signs of being charged, it may be completely dead. However, if the charger acknowledges the battery, you can proceed with the charging process knowing that it should now work as intended.

Why Does Resetting Help Lithium Ion Batteries Charge?

Lithium-ion batteries require a minimum level of charge for the charger to recognize their presence. When a battery is completely drained, it often falls below this threshold, making it appear as if it’s dead. By providing a small amount of charge through the reset process, the battery is brought back to life, allowing the charger to detect and charge it.

Conclusion

By following the steps outlined in this article, you can easily reset and charge a Dewalt lithium-ion battery that is refusing to charge. Remember to exercise caution while working with electricity and ensure that all connections are secure. If the battery remains unresponsive, it may be time to consider replacing it. Good luck, and may your tools always be powered up and ready to go!
