Inspect the Battery

  • Remove the battery from the tool and examine for cracks, corrosion, or dirt.
  • Clean the battery contacts gently with a dry cloth or a soft brush.
  • Ensure the battery is properly seated in the charger.

Test with a Known Good Battery

If possible, try charging a different, fully functional Milwaukee M18 battery. If the replacement charges normally, your original battery may be faulty and need replacement.

Perform a Reset and Cool Down

If your battery has been overheated, allow it to cool for at least 30 minutes before trying to charge again. Some batteries have built-in protection that requires a reset, which can be done by disconnecting the battery from the charger and letting it sit for a few minutes.

Replace or Repair Components

If all previous steps fail, consider replacing the battery or the charger. Contact Milwaukee customer support for warranty options or professional repair services.
