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.



get a set of batteries like this:

they can ring your bell continuously for 25 years or so



Unless those are of exotic construction, won't they have
self-discharged within a couple years' time?
