Do these operate off a 10 year battery only?
Asked by: cloe
They are warrantied for 10 years... The batteries 3-AA don't 10 years. Although some fire alarms do have Li-Ion battery that last ten years.

The other night when one went off (because we were cooking!) it was very nice that the ones upstairs also started beeping. This is an important safety feature for us as so we could hear an alarm throughout our home.

We bought them because we were required by code to have interconnected smoke and carbon monoxide detectors, and these are some of the few battery operated ones on the market. They go through batteries very quickly (about every 3-4 months), which I suppose is to be expected from the wireless feature. We've had these nearly two years. After about 15 months of use, they began going off randomly, at random times. This happens about once a month. Sometimes one in a bedroom behind a closed door will start alarming. The batteries are fine, nothing has changed in the room, but the alarm is going off. It's extra fun when this happens in the middle of the night. When the random alarm goes off, the interconnected feature does NOT work. Only one alarm goes off, not all the detectors in the house. When tested, the interconnected feature still works (i.e. when I press the test button, all detectors in the house cycle through the alarms), but this makes me dubious the interconnected feature would work in case of an actual alarm.
