Hello:

Have been buying a bunch of those standard 9V batteries (a few different
brands) over the past few months, and have noticed that instead of 9V they
have been measuring out, with a VOM, at around 10.0 to 10.25. This is under
no load.

Anyone else notice this ?

Was wondering if this might be the cause of all the problems I've been
having with my fire alarms
giving 3 to 4 chirps, around once a day ?

It's probably the same type of chirp signal that the unit gives when the
batteries are low.

Thanks,
Bob


Hi,
How accurate is your meter? Sounds like it is out of calibration.
Clue is different betteries showing same sort of reading.
