| Connection and Contact Points | Dirty or loose contacts can interrupt charging. |

| Battery and Charger Indicator Lights | LED indicators provide clues on the charging status or errors. |
Check the Charger and Power Source
- Ensure the charger is plugged into a working outlet. Test the outlet with another device if needed.
- Inspect the charger’s power cord for damage or frays. Replace if damaged.
- Verify the charger’s LED indicator is on or flashing as expected. Refer to your model’s manual for indicator meanings.
Inspect and Clean Battery Contacts
- Remove the battery from the charger and power tool.
- Wipe the battery contacts and charger terminals with a dry, clean cloth to remove dust or debris.
- If contacts are corroded or dirty, lightly sand with fine-grit sandpaper and wipe clean.
- Re-insert the battery securely into the charger and check for proper contact.
Test the Battery with a Known Good Charger
If available, try charging your battery with a different DEWALT charger compatible with 20V MAX batteries. If it charges normally, your original charger may be faulty. If not, the battery could be the issue.
Evaluate Battery Condition
Older batteries (over 3 years or heavily used) may have diminished capacity or internal faults preventing charging. Consider replacing the battery if charging issues persist after troubleshooting.
Monitor Environmental Factors and Temperature
Ensure the battery and charger are used within the recommended temperature range (generally 32°F to 104°F). Charging outside this range can prevent charging or damage the battery.
