Step 2: Inspect and Clean Battery Contacts
- Remove the battery from the charger and power tool.
- Use a dry cloth or a cotton swab with a small amount of rubbing alcohol to clean the metal contacts on both the battery and charger.
- Check for corrosion, dirt, or damage. Replace if contacts are severely corroded or damaged.
Step 3: Test the Charger and Battery
- Try charging a different, known-good DEWALT battery with the same charger.
- If the second battery charges normally, the original battery may need replacement.
- If not, the charger could be faulty. Consider testing with a different charger compatible with your battery model.
Step 4: Address Overheating and Battery Age
If the battery feels hot, let it cool down for at least 30 minutes before attempting to charge again. Batteries can temporarily refuse to charge if overheated or too old. If your battery is several years old or shows signs of damage, replacing it might be necessary.
Additional Tips & Safety Warnings
- Always use genuine DEWALT chargers and batteries to prevent compatibility issues.
- Never force a battery into a charger or tool — if it doesn’t fit properly, it may be damaged.
- Handle batteries carefully to avoid punctures, cracks, or exposure to liquids.
- If a battery leaks, avoid contact with the fluid and dispose of it following local regulations.
