Step 2: Inspect the Charger and Power Source

  • Check that the charger is plugged into a functioning outlet. Test the outlet with another device if needed.
  • Look for any visible damage to the charger or power cord.
  • If your charger has indicator lights, observe if they turn on when plugged in. Refer to your specific charger model’s manual for details.

Step 3: Test the Battery with a Known Good Charger

If available, use a compatible DEWALT charger to test your battery. If it charges normally, the issue might be with your original charger.

If the battery still does not charge, move to the next step to test the battery itself.

Step 4: Examine and Clean Battery and Charger Contacts

  • Use a clean, dry cloth or a small brush to remove dirt, dust, or corrosion from the contacts on both the battery and charger.
  • Ensure contacts are dry before attempting to charge again.

Step 5: Test or Replace the Battery

If cleaning doesn’t work, try testing the battery in another DEWALT tool or with a different charger. If it still doesn’t charge or power the tool, it’s likely faulty and needs replacing.

Consider replacing with a DEWALT 20V MAX 5 Ah Lithium-Ion Battery (ASIN: B00KQU1ENG) for reliable performance.
