- SStanley NguyenJul 28, 2025
If your GreenWorks Battery Charger isn't working and the LED is flashing red, it indicates a defective mode. This could be due to a faulty battery pack or charger, or a poor connection between them. Here's what you can do: 1. Remove and reinsert the battery pack into the charger to ensure a secure connection. 2. Try charging a different Greenworks battery pack to see if the issue is with the original battery. 3. Unplug the charger, wait for the red LED to turn off completely, and then plug it back into the power supply.
