While I did miss out on the 10-year CO2 detectors because I didn't know what to buy if it wasn't listed online as compatible with the mounts I already had, I did buy the 10-year smoke detectors for the house because my brother said he could install them no matter what kind of mount there was.
Thrilled to at least have four of the seven detectors off the cycle of battery replacement, I went back to the home improvement store and bought a four pack, as well as four adapters.
Those adapters are really handy because it saved rewiring and made the replacement quick and easy. About half an hour to do the four smoke detectors and the two CO2 detectors that I didn't replace because ladder.
I can't even begin to tell you how much peace of mind I have knowing those smoke detectors are not going to chirp at me. I wish I'd gotten the 10-year CO2 detectors, too, for total peace of mind, but next time I replace them, I'll do that.
You'd think they would have come up with this 10-year battery thing decades ago. Is there anyone who doesn't hate the chirping?
When I bought the CO2 detectors because of the one was chirping, the woman checking me out said she and her husband couldn't get theirs off the mount when it was chirping and they used a baseball bat. That should have been a message a long time ago about how freaking annoying those things are.
At least my house is 57% done with battery issues. Wish it was 100%, but next time.
