Check the Charger and Power Source

  1. Ensure the charger is plugged into a working outlet. Test the outlet with another device.
  2. Inspect the charger cable for visible damage or fraying. Replace if necessary.
  3. Make sure the charger port is free of dust or debris. Clean gently with a dry cloth.

Inspect the Battery

  1. Remove the battery from your DEWALT tool and charger.
  2. Check for any visible damage, corrosion, or dirt on the contacts.
  3. Clean the contacts with a dry cloth or a soft brush. Avoid using water or liquids.

Test the Battery and Charger Compatibility

Use the original DEWALT charger intended for your battery (e.g., DCB115). Using other chargers may not provide proper voltage or current.

Try a Known Good Battery or Charger

  1. If available, test with a spare compatible battery or charger to identify if the issue is with the battery or charger.
  2. If the spare works, replace the faulty component. If not, proceed to battery replacement.

Monitor Charging Conditions and Battery Age

Avoid charging in extreme temperatures. Ideally, charge at room temperature (around 20°C / 68°F). Consider replacing batteries older than 3-5 years or showing reduced runtime.
