- Try a different compatible DEWALT charger if available.
2. Inspect and Clean Battery Contacts
- Remove the battery from the charger and the tool.
- Use a dry cloth or a soft brush to gently clean the metal contacts on both the battery and charger.
- Make sure no dirt, debris, or corrosion is blocking the contact points.
3. Assess the Battery Condition
Examine the battery for any visible damage, swelling, or corrosion. If the battery appears damaged or swollen, it should be replaced.
If the battery looks fine, proceed to test with a different charger or battery to isolate the problem.
4. Test with Alternative Equipment
- Use a different DEWALT charger compatible with your battery to see if it charges.
- If possible, try your battery on a different charger or another similar battery on your charger.
- If the battery charges with another charger, the original charger may be faulty. If not, the battery is likely the issue.
5. Allow Overheated Batteries to Cool
If your battery was recently used heavily or in hot environments, it might be overheated. Remove it from the charger and let it cool at room temperature for at least 30 minutes before attempting to recharge.
Overheated batteries may not accept a charge until cooled down, preventing damage and ensuring safety.
