Just removed the cover. On mine, there is a piece of double sided tape, 2"x1", bottom middle, sticking the back cover to the battery. The battery pack's black skin ripped as I pulled the cover off. I was able to peel the skin from the tape and reposition on the batteries. Don't think this black skin is nothing more then a way to print branding and other texts onto the batteries.
