Thanks for your simply stated, (aka: not unnecessarily wordy), posts on the subject of CO detectors.

I just ordered 4 Kidde C3010D CO detectors to replace my 9v battery powered CO alarms, (2 in my coach and 2 in my home), here: Robot Check

It will be nice to have CO alarms that will last for 10 years without having to replace the batteries every year.

I now know why some folks have 6315 entries on these list. The man asked why one detectors might last longer than another. That is such a long answer it just can not be answered here. It involves really deep electronic, chemical and scientific knowledge of the internal workings of the sensing unit. the short answer is it reused the oxygen in the room for replenishment in the water reservoir.

Just a note: do you know which manufacture has had the most recalled smoke and co detectors - look around - Personally I would only use a professional CO detector that I could test with a known real gas test and not one that uses a push button that only test the circuit that makes the noise not the sensor. good luck with those units in the MH's.

BUT if you really wish to know as much as we must learn go here and read. Then you might know why your choice may not be the most informed purchase. Key word Hydrogen proton and freeze conditions.

I had a Kidde CO alarm in my home a few years ago that alerted me to a problem. I can say with certainty that I would nor be making this post if I didn't have it. It was not this model (it was the nighthawk version that powers off of 120v) but same company so I have first hand knowledge of its ability to perform correctly. I understand that its not what you sell, but that does not mean its not a good product. I have no dog in the fight so to speak, I just know what works.

I don't have a dog here either and could care less what someone wishes to purchase. I am only the messenger. I only answered based on 35 years in this business as to code issues such as where to place and how to use. I am still replacing some units installed 25 years ago because they should last a life time but fail. BG10 example.

I am glad you were protected by the very item which was recalled. I had one of them in my home to but the recall was Millions over all.

WASHINGTON, D.C. - In cooperation with the U.S. Consumer Product Safety Commission (CPSC), Kidde Safety, of Mebane, N.C., is voluntarily recalling about 1 million carbon monoxide alarms, including 650,000 Nighthawks and 350,000 Lifesavers.
More than 1.2 million smoke alarms and combination smoke/CO alarms were recalled because they could fail after a power outage.

The recall involved certain Kidde residential smoke and smoke/CO alarms sold at several retailers including Home Depot, Menards and Amazon.com. The alarms were sold between January and July 2014 for between $30 and $50.

The recalled alarms are hard-wired into a home’s electric power with battery backup; and the alarms “could fail to alert consumers of a fire or a CO incident following a power outage,” said a recall notice on the Consumer Product Safety Commission website.

“If a power outage occurs at the same second that a unit is performing a sensor health check, the units may go into a ‘latched’ mode, causing them not to alert to the presence of smoke,” said an informational post from Kidde.

Close but no cigar. The ones recalled were co/smoke alarms and not what I had. But hey your the expert and I'm still alive.😁😁

I installed my new CO Kidde Alarm and now waiting for my LP Gas alarm.

When done I will have Smoke, CO and LP Gas.

CO is 3ft up the wall
Smoke Alarm in the ceiling.
LP Gas will be close to the floor.
