Hello, so this battery is pretty old, and I am really carefull with them,extremely, today went for vape shop and I forgot to buy new ones, I have 4x over all, and other pair is in perfect condition, no scraches, but I think I messed this one up while pulling out of a charger (the spring pushed the metal holder end), and tell me am I fine using this one? should I just wrap another layer, or toss?
