Inspect the Battery Contacts
- Remove the battery from the tool and charger.
- Clean the metal contacts on both the battery and the charger with a dry, soft cloth or a small brush.
- Ensure contacts are free of dirt, debris, or corrosion.
- Reattach the battery securely to the charger and see if charging begins.
Check the Battery Temperature and Age
Batteries should be charged at room temperature, ideally between 50°F and 77°F (10°C-25°C). If the battery feels hot or cold, move it to a warmer or cooler environment and wait at least 30 minutes before trying again.
If your battery is several years old or shows signs of damage, it may no longer hold a charge and might need replacing.
Test with a Known Good Battery or Charger
- If available, try charging a different, compatible DEWALT battery with your charger.
- If the known good battery charges, your original battery may be defective.
- Alternatively, test your battery on a different compatible charger to determine if the charger is faulty.
Replace Faulty Components or Battery
If all previous steps fail, consider replacing the battery or charger. For batteries, check if they are within warranty or need replacement due to age or damage. For chargers, contact DEWALT service or consider a replacement to ensure safety and compatibility.
