Test the Charging Station and Power Source

  • Plug the charger into a different power outlet to rule out outlet issues.
  • Check for any visible damage or frayed cords on the charger.
  • Use a multimeter to verify the charger outputs the correct voltage as specified by DEWALT.

Evaluate the Battery Condition

If your battery is several years old or has been heavily used, it might have lost capacity. Try charging a different, known-good battery to see if the problem persists. If other batteries charge normally, consider replacing the faulty battery.

Troubleshoot Internal Damage

If the above steps don’t resolve the issue, the battery or charger might be internally damaged. Look for swelling, leaks, or corrosion on the battery. If present, replace the battery or seek professional repair for the charger.

Preventative Tips and Warnings

  • Avoid charging batteries at extreme temperatures; ideal conditions are between 50°F and 104°F.
  • Regularly clean contacts and store batteries in a cool, dry place.
  • Do not attempt to repair internal components yourself; contact DEWALT support if needed.
