Ensure Proper Connection and Power Source
- Plug the Milwaukee charger directly into a working electrical outlet. Avoid extension cords or power strips that may be faulty or overloaded.
- Place the battery firmly into the charger, ensuring the metal contacts align properly and sit flush without wobbling.
Inspect the Battery and Charger for Damage
- Check the battery for swelling, cracks, corrosion, or dirt on the contacts. Clean contacts gently with a dry cloth if dirty.
- Examine the charger for cracks, broken parts, or burnt smell. If damaged, replace the charger.
Test with Additional Batteries or Chargers
- Try charging a different Milwaukee M18 battery to see if the issue persists.
- If available, use a different Milwaukee-compatible charger to verify whether the problem is with the charger or battery.
Allow Batteries to Cool and Retry
If your battery feels hot, let it cool down for at least 30 minutes before attempting to charge again. Overheated batteries often prevent charging to protect internal cells.
Reset and Update
- Unplug the charger and remove the battery. Wait for a few minutes, then reinsert and reconnect to power.
- Ensure your charger and batteries are compatible and up to date, especially if using high-capacity or extended-range batteries.
