We got lucky today.
Our alarm system has motion detectors and they are powered by the CR123 batteries. The main alarm system is of course on the house electric system with a battery backup. Anyway, at 9:30 AM or so, the system alerted us that one of the detectors had a low battery. During the day time awake hours! I thought those were like smoke detectors, and only went off at 3:00 AM or so. This one must be defective to have gone off in the middle of the work day. I suspect the real reason it went off is it is one that is normally sold to people that work the graveyard shift and only sleep in the day.
The sensors for the garage doors are battery operated as well. I think most everything else is wired in. My system sends me an text message and an email that a sensor has failed, and what sensor, and as soon as I try to remove it to change the battery it alert me that it is being tampered with, and as I replace it, another tamper alert. I finally got everything back to normal. I keep the CR123s in stock as my weather station uses them as well.
