Step 2: Inspect the Battery
- Remove the battery from the tool and look for any physical damage, swelling, or corrosion on the contacts.
- Clean the contacts gently with a dry cloth or a gentle brush to remove dirt or debris.
Step 3: Test the Battery and Charger
Use a known good Milwaukee battery and charger to determine which component may be faulty. If the replacement charges normally, the original battery or charger is likely the issue.
Step 4: Reset and Recondition the Battery
If the battery is old or has been stored for a long time, try fully discharging it and then charging it back to recalibrate. If it still won’t charge, consider replacing the battery.
Step 5: Replace the Battery or Charger if Necessary
If all previous steps fail, replacing the battery with a high-capacity model like the Milwaukee 48-11-1850R or the M18 REDLITHIUM HIGH Output XC6.0 may restore charging. Similarly, a faulty charger may need replacement.
