Key Takeaways
| Check Battery Compatibility | Ensure you’re using compatible Milwaukee batteries and charger. |
| Inspect for Damage | Look for physical damage or corrosion on the battery and charger. |
| Test the Charger | Verify the charger is functioning correctly with a known good battery. |
| Clean Contacts | Remove dirt or debris from battery and charger contacts. |
| Replace Faulty Batteries | Use high-quality Milwaukee batteries for reliable charging. |
Step 1: Verify Battery and Charger Compatibility
Make sure the battery and charger are designed to work together. For Milwaukee M18 tools, only use Milwaukee M18 batteries and chargers. Using incompatible units can prevent charging and damage the components.
Step 2: Inspect for Damage and Corrosion
- Remove the battery from the charger and check for visible damage, cracks, or corrosion on the battery terminals and charger contacts.
- If corrosion is present, clean the contacts gently with a dry cloth or a small brush.
Step 3: Test the Charger with a Known Good Battery
If possible, test the charger with a different, fully functional Milwaukee battery (such as the Milwaukee 48-11-1850R 5.0Ah XC Extended Capacity Resistant Battery). If the charger charges this battery properly, the issue is likely with your original battery.
Step 4: Clean Contacts and Reassemble
- Use a dry cloth or isopropyl alcohol to clean the battery and charger contacts.
- Ensure contacts are dry before reattaching the battery and plugging in the charger.
Step 5: Replace or Repair Faulty Batteries
If your battery still won’t charge after cleaning, it may be defective or worn out. Consider replacing it with a high-capacity Milwaukee battery, such as the Milwaukee M18 REDLITHIUM HIGH Output XC 6.0Ah Battery Pack, which offers reliable power and longer runtime.
