Key Takeaways
| Battery temperature | Ensure the battery is not hot or cold, as extreme temperatures hinder charging. |

Step 1: Check the Battery Temperature
- Remove the battery from your tool and charger.
- Allow it to reach room temperature (around 20°C or 68°F).
- Avoid charging if the battery feels hot or cold, as this can prevent charging or damage the battery.
Step 2: Inspect the Charger and Connections
- Verify the charger is plugged into a working outlet.
- Ensure the charger’s LED indicator shows it’s functioning correctly.
- Connect the battery securely, making sure the contacts align properly.
Step 3: Test with a Different Charger or Battery
- If available, try charging a different compatible DEWALT battery with your charger.
- If the battery charges on a different charger, your original charger may be faulty.
- If the battery still doesn’t charge, it might be the battery itself that’s defective.
Step 4: Examine and Clean Battery Contacts
Use a dry cloth or a soft brush to clean any dirt or corrosion from the battery contacts and charger ports. Dirty contacts can prevent proper charging and should be carefully cleaned.
Step 5: Consider Battery Age and Condition
If your battery is several years old or has been heavily used, it may have reached the end of its lifespan. In this case, replacing it with a new DEWALT battery could be necessary for reliable charging and performance.
