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.

I have the same issue when the temperature change. I start getting low battery indicators. These batteries are not cheap. Simply safe are not giving them away for free this is definitely an issue they need to address. Last winter I changed about 6 batteries and they starting again this year and these are inside the house with average temperature of 68. Also have a sensor on the metal door and a smart lock on the metal door that continue to tell me they can't communicate with the base station, with the constant increase of monitoring fees simply safe is now not anymore cheaper than ADT with faulty equipment

My SS system is going on 20 months, and the Duracell Lithium 123 and 2032 batterties all reported "low battery" warnings in the 12 to 14 months after installation. Hence, the Duracell's that were installed at the factory by SS were junk, plain and simple. The second SS system I have at my 2nd home - now beginning its 11th month since installation - has had 4 low battery failures, and I'll be changing them ALL when I get backto that home in four weeks. All the Duracell's I've changed out so far have registered in the 2.86 to 3.05 range, so they really don't work well with the SS systems IMHO. The batteries I've swapped them out with are Everyready Lithiums, and have had no failures yet. Had I known Duracells were so unreliable I would have replaced them all at initial installation, and would now recommend to anyone installing their SS system to do so.
