Perhaps “ENCASED in cardboard” would be a little more accurate.
I did something like this once: I took a remote control car battery & used it to provide additional charge to my portable DVD player. I wanted enough juice to watch one more movie on the airplane. (It worked, but I was always afraid of what that battery pack & all the extra wires & connectors looked like on the way trough security screening.)

So we’re taking the most useful part of a battery (reusability) and throwing it away? Furthermore, we’re encasing it in cardboard to make disposing of a highly toxic device feel environmentally friendly?
*sigh*
