By performing this reset, you’re rebooting the Battery and giving it a fresh start. After resetting the Battery, reinsert it into the charger and check if it can charge appropriately.

Checking The Charger

If resetting the Battery didn’t solve the issue, the next troubleshooting step is to check the charger. A faulty charger can prevent the Battery from charging correctly. Here are a few things you can do to ensure that the charger is working correctly:

  1. Examine the charger for any obvious damage or disconnected parts.
  2. Clean the charging terminals on the Battery and the charger to remove debris or corrosion.
  3. Try charging a different Dewalt 20V battery with the same charger to see if it charges correctly.

If the charger is damaged or not working correctly, you may need to replace it to solve the issue with your Battery not charging. However, if the charger works fine with another battery, the problem likely lies with the Battery itself.

Jump-starting The Battery

If resetting the Battery and checking the charger didn’t work, you can try jump-starting the dead Dewalt 20V battery. This method involves using a good battery to provide a charge to the dead one. Here’s how you can jump-start your Dewalt 20V battery:

  1. Get a fully charged Dewalt 20V battery.
  2. Connect the positive terminals of the good Battery and the dead Battery.
  3. Connect the negative terminals of both batteries.
  4. Leave the batteries connected for a few minutes to allow some charge to transfer.
  5. Disconnect the batteries and try charging the previously dead Battery again.

Jump-starting the Battery can kick-start the charging process and revive a dead battery. However, this method may only work in some cases, significantly, if the Battery is completely damaged.

By following these troubleshooting tips, you can revive your dead Dewalt 20V battery and avoid the cost of purchasing a new one. Always prioritize safety when handling batteries and chargers; if the issue persists, it may be best to seek professional assistance.

Signs Of A Bad Dewalt 20v Battery
