Key Takeaways

Step 1: Confirm the Blinking Pattern
Observe the pattern of the red blinking light. A slow blink often indicates a temperature issue, while rapid blinking suggests a fault or battery problem. Refer to your charger’s manual for specific blinking codes.
Step 2: Check the Battery and Its Compatibility
- Remove the battery from the charger.
- Inspect the battery for any visible damage, swelling, or dirt on the contacts.
- Try charging a different battery compatible with your Milwaukee M18 system.
Step 3: Clean the Charger Contacts
- Use a dry, soft cloth or a small brush to clean the metal contacts on both the battery and charger.
- Avoid using liquids or abrasive materials.
Step 4: Ensure Adequate Ventilation and Cooldown
If the charger or battery feels hot, unplug and let them cool in a well-ventilated area. Overheating can cause red blinking as a safety measure.
Step 5: Test the Charger and Batteries
Reconnect the battery and observe the blinking. If the red light persists, try charging a different compatible battery or test the charger with known good batteries.
