Step 1: Inspect the Battery and Charger

  1. Remove the battery from the tool and inspect it for any visible damage or corrosion on the contacts.
  2. Check the charger for any cracks, burn marks, or debris.

Step 2: Clean the Contacts

Use a dry cloth or a soft brush to gently clean the metal contacts on both the battery and charger. Dirty contacts can prevent proper charging.

Step 3: Test the Charger

  1. Plug the charger into a different power outlet to rule out electrical issues.
  2. Observe the LED indicator; a flashing or no light may indicate a problem.

Step 4: Try a Known Good Battery

If available, test your battery with another DEWALT charger or test your charger with another compatible battery. This helps identify if the problem is with the battery or the charger.

Step 5: Check the Battery Temperature

Ensure the battery is at room temperature. Batteries may refuse to charge if too hot or cold. Wait for it to return to normal temperature before trying again.

Additional Tips & Warnings

  • Never attempt to open or repair the battery or charger yourself, as it can be dangerous.
  • Replace old or damaged batteries to ensure safe operation.
  • Use only genuine DEWALT chargers and batteries for optimal safety and performance.
