I previously ordered 16 pieces of the same battery cells,Upon installation, one turned out to be defective, so I contacted the manufacturer and purchased on emore cell. Upon installation, the last purchased cell doesn't take a charge at all. Its completely dead. It does look like the used cell in the new housing. I will try to contact the manufactured to resolve the problem
