Step 1: Identify the Blink Pattern
Observe the blinking red light on your Milwaukee charger. A single blink, rapid blinking, or a specific sequence can indicate different issues.

Step 2: Check the Battery
- Remove the battery from the charger.
- Inspect the contacts for dirt, debris, or corrosion. Clean gently with a dry cloth if needed.
- Try inserting a different, known-good battery (such as the Milwaukee M18 5.0 Ah XC or 6.0 Ah High Output battery) into the charger.
- If the charger recognizes the new battery and charges it properly, the original battery may be faulty.
Step 3: Verify Charger and Connection
- Ensure the charger is plugged into a working outlet. Test with another device if necessary.
- Check the power cord and port for damage or looseness.
- Place the charger and battery in a well-ventilated area and avoid extreme temperatures.
Step 4: Test with a Different Battery or Charger
If available, try charging a different battery with your charger or vice versa. This helps pinpoint whether the issue is with the charger or the battery itself. If the problem persists despite these swaps, the charger might need servicing or replacement.
Additional Tips and Warnings
- Do not force batteries into the charger; ensure they are compatible and properly aligned.
- A blinking red light after a recent impact or exposure to moisture may indicate internal damage. Avoid using damaged chargers or batteries.
- If troubleshooting doesn’t resolve the issue, contact Milwaukee customer support or consider professional repair.
