re: Low battery alert from smoke detector at 1:45am

I had every smoke detector in my house go off all at the same time in the middle of the night
The whole house woke up and I was scrambling through the entire house looking for smoke/fire. They are hard wired to the house along with a battery. I had to cut the breakers off on the house to get them to stop.

Replace them regularly. Problem solved.
Nit so easy with 2 story ceilings. I did learn last time that our local fire station will send guys out to change them all free of charge.

One of life’s greatest certainties is that the smoke and CO detectors will always start chirping around 2 AM. Other than it being a sinister plot, I theorize that since battery charges drop with temperature, those on the edge drop below the alarm set point when the house gets cold.

It sounds like your system functioned exactly as designed. If smoke is detected, the system wants everyone awake, and out of the house. If smoke is detected, ALL the alarms on ALL the CO and smoke detectors are activated.
BTW: The "chirpers" are your smoke detectors. If smoke is detected, the noise ain't just a little bit of chirping.

Does it immediately make you think of amateur porn?

For most smoke detectors, if you just pull it off the wall and pull the battery out, it will shut up. The trick is figuring out which fricking one is chirping

Ours is wired into the house. The battery is just backup.

Why do these things always happen in the middle of the night?
Because the temperature is cooler

The rule of thumb is to change them every time the time changes.
Worked out perfect in this case.

I once let the battery get low in every one of them in my house. The intermittent chirps became strangely soothing.

33% chance straight up. But also you don't really even notice when it goes off during the day.

I'd like to see your oil change schedule.
Don't confuse changing the battery in a smoke or CO detector normally done on relatively short time schedules, with that of the CO detector element. For home systems, this usually involves having to replace the entire system.
BTW, from your title Doctor Technical, I would have thought You knew that. My doctorate is in Chemistry and engineering from Alabama in 1974.

you replace them every New Year’s Day you shouldn’t have that problem.
Sounds like a lot of unnecessary work. Rather just wonder aimlessly around the house in the middle of the night to figure out which one is chirping

standard or DST?
That question only applies in the Fall.

Change the batteries twice a year to be safe.
Do so when you fall back and spring forward.

Somebody needs to invent a smoke alarm where you can turn the "midnight chirp" off by an app on your phone.
You know, if you change the batteries every October during Fire Prevention Month, the likelihood of an alarm chirping in the middle of the night is pretty much null and void.
Oh, and just how lazy are you that you'd need an app for something like that?????

Temperatures at night are cooler, less movement in the house, less electronics and frequencies in constant use, the air itself is more still(no walking, no doors opening and closing, things moving etc). It’s a chem reaction within the battery when it’s on the lower end of life and there’s no stimulation, it chirps.
First sentence is correct. Lower temps and lower humidity will have a battery that’s borderline bad drop into the dying stages(as the detector is looking for) and chirps.

Because alarm sensors wear out, replace each alarm at least every 10 years. Also, alarms have labels showing when they were made. If you don't see a label, the alarm is old and should be replaced.
Places like Lowes, has 5 or 6 in a box.
Most have electric with battery backup. Try to buy the same type.
