Step 1: Confirm the Blinking Pattern
Observe the blinking pattern of the red light. A slow blink might indicate a different issue than a rapid blink. Refer to your Milwaukee charger manual to interpret the specific pattern.
Step 2: Check the Battery Placement and Compatibility
- Remove the battery from the charger.
- Inspect the battery terminals for dirt or corrosion.
- Reinsert the battery firmly, ensuring it clicks into place.
- Verify that you are using a compatible Milwaukee M18 battery, such as the 5.0 Ah XC or 6.0 Ah High Output models.
Step 3: Inspect for Damage and Clean Contacts
Look for any visible damage or cracks on the battery and charger. Use a dry cloth or a soft brush to clean the metal contacts on both the battery and charger to ensure a good connection.
Step 4: Reset and Test the Charger
- Unplug the charger from the power outlet for 30 seconds.
- Press and hold the reset button if available, or simply reconnect the charger.
- Insert the battery and observe the blinking light. If it turns green or stops blinking, the issue is resolved.
Step 5: Replace Components if Necessary
If the red blinking persists after cleaning and resetting, consider testing with a different compatible battery or replacing the charger if it appears faulty. Batteries like the Milwaukee 48-11-1850R 5.0 Ah XC or 6.0 Ah High Output models are recommended for best performance.
