Step 1: Inspect the Battery and Charger

  1. Remove the battery from the drill and examine it for any visible damage, swelling, or corrosion.
  2. Check the charger for any signs of damage, frayed cords, or debris on the contacts.

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. Dirt or oxidation can prevent proper charging.

Step 3: Test the Charger and Battery

  1. Plug the charger into an active power outlet and verify the charging indicator lights (refer to your model’s manual).
  2. Insert the battery fully into the charger and observe if the charging light activates. If not, try another compatible charger if available.

Step 4: Try a Different Power Source

Sometimes outlets or power strips cause issues. Plug the charger directly into a different, reliable outlet to rule out power supply problems.

Step 5: Assess Battery Age and Capacity

If your battery is over 2-3 years old or shows reduced runtime, it may need replacement. Consider testing with a known good battery or replacing it if necessary.
