I bought my home in 2024. First month I replaced every smoke detector in my home with new Kidde 10 year lithium battery smokies. 7 total in my house and two CO/Smoke combo units. Since then, I have had to replace each of the three bedroom units upstairs (3 different rooms) at least two times per room. Without fail they last about 6 months and then start randomly chirping in the night and I have to permanently disable them. 7 brand new smokes, but only the units in these three bedrooms are constantly failing early and I cannot understand why. These are just standard smokies, not the combo units. Why these three rooms specifically when everything else is lasting years as expected? Starting to think it’s ghosts.
