What to do if my GreenWorks Battery Charger shows a defective mode (LED flashes red)?
- JJeremy MorrisAug 4, 2025
If your GreenWorks Battery Charger is in defective mode (LED flashes red) try removing and reinserting the battery pack. If that doesn't work, try charging a different battery pack. Additionally, unplug the charger, wait until the red LED goes out, and then reconnect it to the power supply. This may be due to a defective battery pack or charger, or a bad connection.
