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.
