Nights are getting cold. Some sensors reporting "Low Battery" but voltage is at or near 3V...
It's getting cold at night. Some of my sensors are reporting "low battery." The base station is suddenly "talking to me about it" in the middle of the night, which is unnerving...
1. The entry sensor on the back door of an unheated garage is reporting low battery intermittently, particularly at night. My voltage meter reports 3.07 volts for its CR2032 battery. Doesn't 3.07V indicate a fully charged battery?
2. One of my glass-break sensors is also reporting "low battery" intermittently. It's in a storage room (inside the house) that I do not heat regularly. The battery is a 123 (CR17345) and the voltage tests at 2.78 volts. Isn't a reading above 2.5 volts viable?
I think the cold temperature is a factor. Please advise. And for future reference, I'd appreciate knowing what voltage is considered "dead or near-death" for CR2032 and CR17345 in these particular applications.
Thanks,
Tom

Okay, now that is out of the way, I have used a motion sensnor and entry sensors in my unheated garage for multiple winters (motion for 3, entry sensors for 1. Since I live in the greater Chicagoland area it gets damn cold, one of the those winters included the "polar vortex" and the actual temp (not windchill) got to -38). My garage was in the low single digits and the motion sensor did quite nicely. Ditto last winter with the entry sensors on the garage doors. No battery issues or warnings either. As far as being warned in the middle of the night, shut off the voice on the base. Mine is silent, no lights etc to avoid detection. I suggest replacing the batteries and if still an issue, swap them with sensors in your home. In my case, motions and entry work fine, however, cannot comment on the glass break as I do not have one in an unheated area.

Cold weather is 100% a factor in battery life. How much of a factor is it in your specific situation, temperatures, etc. I can't exactly say but it's a very safe bet that you're going to see diminished battery life in the cold and I don't find the warning messages at night (when it's super cold and the system might think the battery is near death) a surprise at all.
