No but you can get crud in the cheap switches. The way mine worked was
that the battery was in series with the switch so until you press the
button its just off. Battery should last similar to shelf life. The
only way it could have sent a false signal is if the switch was
shorted.

No. Smoke detectors have to have a special circuit to keep track of
when the battery voltage goes down, because it's a matter of life and
death.
OTOH if the doorbell doesn't work, people can knock. They can bang on
the window, they can telephone, they can send a letter.

Carbon zinc, alkaline, nickel-cadmium, lithium ion, NiMH3?????
But I didn't post just to be sarcastic. As it happens, my wireless
doorbell rang at 5 this morning, well before I had to get up. I was
going to ignore it but I thought, Maybe my car is on fire. If it
were, it would probably be too late to do anything about it, but I got
up. I looked out the front window and saw no flames, and no one on
the sidewalk who could have rung the bell.
I went back to bed, and 10 minutes later it rang again.
bzzzzz-=-==bzzz=-=-=bzzzz. By this time I was awake. I'd forgotten
and left the computer on so I went to the computer. It went off 10 or
15 times in the next hour. I've had this thing for about 10 years and
this is the first trouble it gave me. A real cheap one too, maybe
%2.50 from Sunset House, a mail order place.
But I didnt' use any batteries. I have a real doorbell with a
transformer and a bell in the front hall and the basement, but
couldn't hear it in my 2n'd floor office with the computer fan and
radio. In the basement, I rectify the 18 volt transformer output
and use a resistor to lower the voltage to what the button should
take, and when someone pushes the front door button, the button is
powered and the receiver in the upstairs hall makes noises.
Anyhow, I unplugged the receiver and the wall was very dirty behind
it, even though I had had this thing there for maybe 10 years, and 2
months ago it was barely dirty at all. That's as far as I've gotten
so far.
P&M After tomorrow at noon or so, I won't be around for several days.

And btw, the main doorbell button is as good as new (It's only a year
old) and I have to press it against spring pressure a full quarter
inch to ring the bell. That's not the problem.

Just a thought - I had a similar problem once, but my wireless doorbell
had a set of movable jumpers in both the receiver and transmitter to set
a code. I played with it a little (no manual!) until I got them talking
to each other with a different setting - and the problem went away.

Just place a sign at your door reading:
I don't have a doorbell. Please yell out Ding Dong.
