If the housing is just well made (inside Kunstoffnase, outside somewhat edgy, of course, easily - 9 g), so the fake paper sleeve is too large (stands up and down on) and so badly stuck that everyone notices immediately that the can not be a real battery. It also dissolves the supernatants and overlapping or tears immediately.
Please What is one to do in this small cavity, so that the normal weight (25 g) of a real battery is achieved? Gold, platinum? But the hiding place but to then "cheap".
No, that was nothing! So do not touch.
