Step 2: Examine the Battery

  1. Remove the battery from the drill and visually inspect for damage or corrosion on the contacts.
  2. Clean the contacts gently with a dry cloth or a soft brush to remove dirt or debris.
  3. Reinsert the battery securely into the charger and check for charging signals (LED lights).

Step 3: Test with a Compatible Battery

If available, try charging a different DEWALT 20V MAX battery (like the 5.0 Ah or 2.0 Ah models) to determine if your battery is faulty.

If the new battery charges successfully, your original battery may need replacement.

Always use compatible batteries and chargers to avoid damage and ensure safety.

Additional Tips and Safety Warnings

  • Never use damaged or swollen batteries, as they pose safety risks.
  • Always disconnect the charger from power before inspecting or cleaning.
  • Use only DEWALT approved chargers and batteries to prevent damage.
  • If unsure, contact DEWALT customer service or a professional technician.
