Not without *some* kind of batteries. They might hide something inside so
the externally visible battery could be removed, I suppose.

This reminds me of an old Sun Workstation eavesdropping trick, back when
soundcards were new. Every Sun had a soundcard and a microphone. But every
Sun ran multi-user UNIX. So you log on remotely, record a sound file,
download it, and play it. (Or, if more clever, stream it to yourself in
real time.) And so you hear whatever is going on in the room where the
computer is.
