"Push button battery included, 3 year battery life"


I imagine the 3 year battery life refers to the push button

[Anecdotal, unscientific, and realying on a poor memory.] I recently
had to replace the push button battery (Duracell MN21/23) after about
nine months. I *think* the chime batteries lasted considerably longer,
but I cannot say for definite (I carry a supply of AAs, while sourcing
an MN21/23 is a more memorable event.)

Another consideration. The house that this chime is used in has very
thick stone walls (~ two feet, and subject to damp); in order for the
signal to reach the living room (deaf occupant[1]), the receiver has to
be carefully sited so that the signal needs pass through only the
external wall.

[1] Of course, maybe that's the reason why the battery lasted only nine
months
