Question:
When I got up this morning I noticed that one of my smoke detectors was
chirping about every 30 seconds.
I know that this usually signals that the 9 volt battery needs
replacement. I removed the old battery and did some other chores but
noticed that the smoke detector still kept chirping (without a battery)
which I thought was strange.
I then inserted a new battery but the thing still chirps about every 30 seconds.
What's going on?
Answer:
The terminals may be dirty. Clean them with the eraser end of a
wooden pencil. Try a new battery. You can test a 9V battery by
sticking your tongue across the terminals. It should have a
moderately strong sensation and a strong metallic taste.
Compare to the dead battery.
I had a f(r)iend accidentaly do this to a *90* volt battery
once. It lit his lights thoroughly. ;-)
If all that fails to solve the problem, bite the bullet (as
opposed to licking the battery) and get a new smoke detector.
If you get one that is physically bigger then the old one, it
will hide the faded/clean spot on the ceiling.
