What does Error Code 10 mean on a Milwaukee MX Fuel tool?
Error code 10 indicates a battery fault. It means the battery is not communicating correctly with the tool, either due to low charge, overheating, or a hardware issue.
How do I reset my Milwaukee MX Fuel battery?
Remove the battery from the tool and charger. Press and hold the battery's power button (if present) for 15 seconds. Then insert it back into the charger until fully charged, then try using it again.
Can a dirty battery contact cause Error Code 10?
Yes, dirty or corroded contacts can prevent proper communication between the battery and tool, triggering error code 10. Clean them with a dry cloth or rubbing alcohol.

A blinking red and green light on the charger often indicates a battery fault, such as a defect or an out-of-balance cell. Try resetting the battery; if it persists, the battery may need replacement.
Is it safe to leave my Milwaukee MX Fuel battery on the charger?
Milwaukee chargers are designed to prevent overcharging, but it's best to remove the battery once fully charged. Avoid leaving it on the charger for extended periods (e.g., overnight) to prolong battery life.
