I have not seen an increase in 9 volt
batteries, etc. I would check your meter.
I have seen new ones reading as high at
9.5, but that's about it. BTW, new
digital meters are getting pretty cheap
these days. I picked up a real nice one
from Electronic Goldmine for about $13
when it was on sale. I actually like
it better than my Fluke because it is
smaller and has a continuity beeper. And
it appears to be very accurate.

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
