Greenworks 60V Battery Repair – Replace Dead Cells & Fix Not Charging

My Greenworks 60V battery stopped charging after about 3–4 years of use. The charger showed no power, so I opened the battery to find out what was wrong. In this video, I check the voltage of the individual battery cells and find two cells with extremely low voltage. I then replace the bad cells, reconnect the battery, and test the battery again after charging. 🔧 In this video: • Greenworks 60V battery repair • Greenworks battery not charging • How to check battery cell voltage • Finding dead lithium-ion cells • Replacing damaged battery cells • Testing the battery after repair • Final voltage and charging test ⚠️ SAFETY WARNING: Repairing a 60V lithium-ion battery can be dangerous and may cause electric shock, fire, or serious injury. Battery repair should only be attempted by people with the proper knowledge, experience, and safety equipment. Do this at your own risk. In the end, although the battery worked again, I would personally recommend buying a new battery rather than replacing individual cells because of the safety risks involved. #Greenworks #Greenworks60V #BatteryRepair #BatteryRepair #LithiumIonBattery #DIYRepair #PowerTools #LawnMower
