Inspect and Clean the Charger and Battery Contacts

Use a dry cloth or a soft brush to gently clean the metal contacts on both the battery and the charger. Dirty contacts can prevent proper charging. Avoid using water or liquids that might damage the electronics.

Test the Charger with a Known Good Battery

  1. Insert a fully charged, compatible DEWALT battery (e.g., DCB205-2 5.0 Ah) into the charger.
  2. Observe the LED indicator: a green light typically indicates a good charge or readiness. If the charger doesn’t recognize the battery, it may be faulty.
  3. If the battery charges normally, the issue is likely with your original battery.

Verify Power Supply and Connections

Ensure the charger is plugged into a working outlet. Try plugging into a different socket or power strip. Check the charger’s power cord for damage. Only use the charger provided with your DEWALT tool to avoid compatibility issues.

Replace Faulty Components or Seek Professional Help

If the above steps do not resolve the issue, consider replacing the battery or charger. For persistent problems, contact DEWALT customer service or a qualified repair technician. Using genuine parts ensures safety and compatibility.
