Honeywell says would remove 787 beacons if asked as fire probed

I have a high sensitivity carbon monoxide detector (alarms at 7PPM) in my bedroom. I am told that some pilots of small aircraft use them for flight safety. It comes with an UltraLife lithium-manganese 9-volt battery. Mine never caused a fire. On the contrary, they go dead in about 3 months. The regular 9-volt batteries last about a year in that unit.

I have bought replacements at my local Radio Shack, at big box stores, and on line. They last about 3 months. My guess is that their higher price results in slower turnover. But they should last 5 to 9 years on the shelf. They sure do not.

I conclude that they are a great idea, but badly manufactured. Perhaps some of them short out internally and start fires. I am now back to ordinary batteries.
