Key Takeaways
| Check the charger and battery contacts | Dirty or damaged contacts prevent proper charging. |
| Use the correct charger | Ensure you’re using the charger compatible with your Milwaukee battery. |
| Inspect the battery for damage | Cracks, bulges, or corrosion indicate a faulty battery. |
| Test with a known good battery | Isolate whether the issue is with the battery or charger. |
| Follow safety precautions | Always disconnect power before inspecting or handling batteries. |
Step 1: Inspect the Charger and Battery Contacts
- Unplug the charger from power and remove the battery.
- Visually check the metal contacts on both the charger and battery for dirt, debris, or corrosion.
- Clean contacts gently with a dry cloth or a soft brush if dirty.
Step 2: Verify the Charger Is Functioning Properly
- Plug the charger into a different power outlet to rule out outlet issues.
- Look for indicator lights on the charger; consult your charger’s manual for what they mean.
- If the charger shows no lights or behaves abnormally, consider testing with another compatible charger or replacing it.
Step 3: Test the Battery
- Insert the battery into the charger and observe the indicator lights.
- If the battery doesn’t charge or no lights appear, try using a different, known-good battery.
- If the replacement battery charges normally, your original battery is likely faulty.
Step 4: Check for Battery Damage and Replace if Needed
Inspect the battery for physical damage such as cracks, leaks, or swelling. If damaged, replace it with a new Milwaukee battery compatible with your tool.
Step 5: Seek Professional Help or Replace Components
If troubleshooting doesn’t resolve the issue, contact Milwaukee customer service or a qualified repair technician. Sometimes, internal circuitry or components may fail, requiring professional repair or replacement.
