What is the approximate battery life of the receiver of a wire free door
chime?

For the sake of argument, let's say the unit is used very little and the
receiver does not have a light.

Not having such a device, why would the *receiver* be battery powered
unless you live somewhere without mains electricity?

You can move them about the house with you if, say you were working in
an upstairs room when expecting a parcel / take them into the
conservatory / out to the barbecue. Also you can site them on top of
tall cupboards where they are out of the way and inconspicuous without
trailing wires.

Oddly the transmitter unit in my 4 year old Friedland unit has never
had a new battery (presumably a button cell of some kind), whereas the
sounder has had 3 sets of 2 "C" cells.
