Key Takeaways
| Identify the blinking pattern | Red blinking lights typically signal a charging or battery issue. |
| Check the battery connection | Ensure the battery is properly seated and clean. |
| Inspect for damage or dirt | Look for corrosion, dirt, or damage on the battery and charger contacts. |
| Test with different batteries | Use another compatible battery to isolate the issue. |
| Verify power source and charger condition | Make sure the outlet and charger are functioning correctly. |
Step 1: Power Cycle the Charger
- Unplug the charger from the power outlet.
- Wait 30 seconds to reset the internal electronics.
- Plug it back in and observe the LED indicator.
Step 2: Check the Battery Compatibility and Fit
- Remove the battery from the charger.
- Inspect the battery contacts for dirt, corrosion, or damage.
- Reinsert the battery ensuring it clicks into place securely.
Step 3: Test with a Different Battery
If you have a spare compatible battery (e.g., a Milwaukee M18 5.0Ah or 6.0Ah), try charging it. If the new battery charges without issue, the original battery might be faulty.
Step 4: Examine the Charger and Power Supply
- Try plugging the charger into a different outlet or circuit.
- Inspect the charger for visible damage or dirt on the contacts.
- If available, test with another Milwaukee charger to confirm if the problem persists.
Step 5: Check for Battery or Charger Faults
If the above steps don’t resolve the blinking red light, your battery may be dead or the charger may need professional repair or replacement.
