It may be partly true: as far as I know, NiCd batteries (don't know about
NiMH) will produce a very high current when short circuited, or with a
resistance of less than one ohm across them, but most electronic equipment
has much higher resistances (eg 100 ohms) so this should not be a problem.

I also heard somewhere that Li-Ion batteries can be ruined by shorting
their terminals, due to a buildup of pressure that can't be vented quickly
enough, although I'm not sure if this is true or not.
