I've had one in service for at least a decade. It's outlasted several
of the button/transmitter units. And a second (upstairs) for 3-4 years.
The nameplate current is 50ma (which would be 6W) on one, and about
twice that on the other, but I think that must be when actually making
noise, as I couldn't measure *any* current drain.

You just reminded me of the doorbell at "Neighborhood Bike Works", AKA
"The Bike Church". That outfit uses some space at a church.
There is a sign sying, as best as I remember: "Pull brake lever to ring
doorbell".
They have a handlebar mounted onto something or other close to the
handrail for the stairway for that offbeat entrance into the church
complex. The brake lever is connected to a brake cable, that is routed
through a small diameter hole in the exterior wall. Apparently, the other
end of the brake cable pulls the lever on a bicycle bell that is suitably
mounted.

I don't understand why this is a problem.

Or rechargeables. The precharged NiMH ones seem to hold their charge
for a long time.
Ours just emits a strangled sort of buzz; replacing it with a cheap
wireless one would be a definite advantage if it weren't for the fact
that our friends all know to knock -- anybody who rings the "bell" only
wants to convert us to something or sell us something.

How about a brass door-knocker which needs no electricity from any source?
