Has anyone used these in cold temperatures-- about 50 degrees F? My current smoke detectors chirp (low batt) when it gets cold

I keep my house at 55F in the winter. No chirping. That said, battery voltages dip as a result of cold (although 50F isnt really that cold). Perhaps its just an old battery thats on the edge and the cold pushes it over?

Our house never gets that cold. Chirping is probably coming from the lower output of the battery due to the cold temp. I'm assuming the chirping goes away as the temp rises.

To be on the safe side, I change mine when I change the batteries in my smoke detectors. Never had a low battery alarm within that time frame.

I live in Thunder Bay, and we had many weeks of near -40 below temperatures. Remarkably, these units work. I am exceedingly happy with the units I have purchased. I have owned them for more than one year now, and while I changed out the batteries, I fully expect another great year.

On the sensors I've put in the ground they seem to work fine in the snow. The transmitting part of the unit is mounted above ground, like on a fence post. On my personal ones (I use two) the sensors are mounted on the fences down low while the transmitters are mounted high. You can always adjust the sensitivity of the sensor. Highly recommended system.... especially if 911 is an hour away!

I live in a very cold place, this type (lipo) of battery heats up when in use, but leave out in cold without using will probably ruin them.

I'm very satisfied with mine, I use them on a high drain device and it last a long time. A smoke detector should be a low drain service . Make sure you are charging then properly, my charger is over 10 yrs old and it takes many hours to re these but it does the job. Maybe you have a bad battery, or charger . Try also and see if they work on some other device.

They should last a long time as the unit is direct wired to 110 volts. So it's based on the shelf life of the battery. I have several direct wired smoke detectors and I only replace the batteries when one of them is low, then I replace all of them. batteries. I expect the batteries will last over 2 years.

If you are frequently switching them on and off, CFC's will not last as long. Also they do not like cold temperatures. I live in Washington state. It doesn't get as cold here as it does in Michigan however, I have CFC's in my shop and I have good sucess with them. I have one which has been on 24-7 for 4+ years now. The money savings/value of CFC's are found in applications where they remain on for long periods of time. Also I would recommend reading the manufacture's installation & application guidelines. I have also had CFC's which have burned out earlier than expected but, the money I've saved in KW/hr's, I can still replace them and be money ahead with the same luminescence I would otherwise get from an incandescent with a higher KW/hr requirement. I believe the shorter life expectancy in my application is due to cold temps. For this reason, when I'm in my shop, they remain on for LONG periods of time.

Bill - we have used it in cold weather with very good results (32 degrees and above), but not sure about performance in sub zero weather. Sorry we couldn't be of more help. Have you called the manufacturer for input?

Get a new smoke detector. They get dusty with age and dust sets them off. I hate them

I am not s sure but why would you? The battery should last between 5-7 years and if the cost of the battery exceeds a new smoke detector then you replace the detector. Have to ask the mfg this 1.........

They work beautifully at lower temperatures, I like the snug fit and the insulation is not overly bulky. I can still work the controls and fit my finger into the trigger guard. Excellent for a LEO or hunter! I have cold hands and these worked well this past winter while standing on long posts 2-3 hrs with little movement. I believe they work very well.

Jamster,I have yet to see a led bulb with minimum operating temp less than -22 F. There may be a handful under that but I wouldn't expect it. Only question is how the bulb will respond....will it not work properly during extreme cold or will it kill the bulb...I don't know. If I were you I would buy a cheap led bulb to test it out.

Yes, install one operating at a temperature of 65 degrees Celsius and have not had this problem some above 140 deg. F.

Nah, I'm front ct and have had my light out at night in the single digits and teens and had no problem. Just keep it in my jacket pocket until I need it and pull it out and use it for about 30 min or so each time and it worked np. Probably used it in these Temps about half a dozen times this winter.

We are in Australia and have been using these alarms summer and winter, lowest here would have been -2 degrees. As long as you use non rechargeable batteries they should work fine

I'm also having the same issue with 2 888LM's keeping the lights on constantly. They didn't seem to do it when first installed but nowall the time. I'm wondering if they get more sensitive during colder temperatures.I've turned the motion detection off for now unfortunately.
