Check the Power Source and Charger
- Verify that the charger is firmly plugged into a working outlet. Test the outlet with another device to confirm power.
- Inspect the charger’s LED indicator. A solid or blinking light can indicate different statuses—refer to your charger’s manual for specifics.
- If the charger has a reset button, press it. Replace the power cord if damaged.
Inspect and Clean the Battery Contacts
- Remove the battery from the tool and charger.
- Wipe the contacts on both the battery and charger with a clean, dry cloth. Use a small amount of isopropyl alcohol if needed to remove dirt or grease.
- Ensure no corrosion or debris is present. If corrosion is visible, gently clean with a toothbrush or a soft cloth dipped in alcohol.
Test with a Known Good Battery
If you have spare batteries (such as the Milwaukee 48-11-1850R 5.0 Ah or the M18 REDLITHIUM HIGH Output XC 6.0Ah), try charging a different battery to see if it charges properly. If the new battery charges normally, your original battery may be faulty.
Evaluate the Battery and Charger Condition
Look for signs of physical damage, swelling, or burns on the battery. Discard any damaged batteries and replace them with genuine Milwaukee batteries for optimal performance.
If the charger or battery shows no signs of damage but still won’t charge, consider testing with a different charger or contacting Milwaukee support for warranty options.
Reset and Update Battery Firmware
Some Milwaukee batteries and chargers may benefit from a reset or firmware update. Follow specific instructions from Milwaukee or your battery’s manual for resetting or updating firmware if applicable.
Always follow safety precautions when handling batteries and chargers to prevent injury or damage.
