I have a portable flash-memory recorder which has a mic input.

The input socket has "Plug-In-Power" this provides power to run a
suitably-designed unpowered electret mic which is plugged into the
socket.

If I use one of the older-style electret mics which contains a
battery for its own power then would that severely overload the input
electronics of the flash recorder?

If so then could such an arrangement actually cause damage to those
electronic components?
