Step 2: Test the Charger and Power Source

  1. Plug the charger into a different power outlet to rule out outlet issues.
  2. Check the LED indicator on the charger; it should turn on or show a specific color indicating charging status.
  3. If the charger doesn’t light up, try another compatible charger if available.

Step 3: Use a Known Good Battery

If possible, test with an additional fully charged battery of the same model. If the new battery charges normally, your original battery may be faulty or degraded and in need of replacement.

Step 4: Clean Contacts and Check for Damage

  • Use a clean cloth or a small brush to remove dirt, dust, or corrosion from both the battery and charger contacts.
  • Inspect for visible damage such as bent pins or cracks. Damaged contacts may need professional repair or replacement.

Step 5: Replace Battery or Charger if Needed

If your tests indicate the battery or charger is faulty, consider replacing the defective component. Use genuine DEWALT parts, such as the 20V MAX Lithium-Ion Battery (ASIN B00KQU1ENG) for reliable performance.
