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?

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

"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 :)
Best regards,
Jon C. |

I'd say alkaline batteries could be reasonably expected to last 6 months to
a year, with limited use. It might vary quite a bit product to product
though. |

get a set of batteries like this:

they can ring your bell continuously for 25 years or so |

Merely because that's how they design some of them.
I happen to have one for a side entrance, though I forget
the model. Don't recall much about it actually, but I think
the receiver takes 2 x C cells and hasn't needed them
replaced since it was installed a year ago.
As for the specific product OP is considering either the
manufacturer can provide this data or it'll have to be
measured in use (current consumption as a rough calculation
applied to the expected capacity and shelf life of the type
of battery used). |

The Friedland EVO 50 quote 18 months for receiver (3AA's), about 5 years for
bell push (3v Lithium CR2032).

Bells/chimes here in the U.S. when hooked to main power in my
experience use a transformer to step power down to low voltage
12 or 24?). This obviates armoring the wires and makes wiring easier,
plus provides fatal shock protection for a hapless doorbell ringer
who might be standing on a wet welcome mat. Welcome - ZAPPP!
The wireless units are much easier to install, and can be located
anywhere with no connections but a couple nails or screws.
In my experience the battery for the button lasts a minimum of 2 years
and for the chimes even longer. The button takes an AAA and the
inside probably one or two C's.
I live near Chicago where winters are typically cold. The outside
button never gets wet as it is protected by a porch awning.
The bell/chime is little used, maybe averaging once a week.
I put this in about 10 years ago.
I wouldn't buy a unit that uses anything but common batteries.

Mine has been in for at least six years and the batteries in the
transmitters and receiver/gong are still the originals. Someone living
in a really cold climate might find the outdoor batteries would have a
shorter operational life or at least would be less willing to operate at
sub-zero temperatures.

By the time ten minutes of continuous ringing has gone by, the advantage
will cease to be obvious.  |

Our wireless doorbells seemed to do nothing but die, they were
totally hopeless, in the end I put a wired one in myself which
is still going strong, the wireless ones just seemed to stop
working for some reason after about 12 months and no end of
fiddling with them would get them working again, it also
seemed regardless of the amount of money we spent on them as
well. |

They are not fighting with your wireless network are they ?
Both my wireless meat thermometer and my little Chinese weather
station quit when my wifi network is running.
