Inspect the Battery and Charger
- Look for any visible damage, corrosion, or debris on the battery contacts and charger ports.
- Clean contacts gently with a dry cloth if dirty or corroded.

If the battery is old or has been heavily used, it may no longer hold a charge and needs replacement.
Check the Charger Functionality
Use a multimeter to test if the charger is outputting the correct voltage as specified by Milwaukee (typically around 18V for M18 chargers).
If the charger isn’t working properly, consider replacing it or testing with a compatible charger.
Replace or Recharge the Battery
If the battery is faulty or no longer holds a charge, replace with a Milwaukee-compatible battery such as the Milwaukee 48-11-1850R 5.0 Ah XC Extended Capacity Resistant Battery.
