Скачать или смотреть Battery Rebuild & Refresh Vintage Cordless Impact Wrench | Makita 6900D

I'm really happy when I first see it, but after looking inside it's an old model cordless impact wrench by MAKITA. There is also a charger in the box. The only one problem is the dead battery. I try to revive the battery, but the charger doesn't charge it. Finally, I rebuild this battery by replacing new battery cells.
