Voltages drop in the cold, and the middle of the night is usually the coldest. So that's why this is probably not far from reality.
Wouldn’t the lower temperature make it highly likely that the low power beep occurs only during the middle of the night, but not during the day?
That's if the alarm reads the voltage directly. But if the low voltage flips a switch that stays flipped, then no.
Ok, but the probability would still be shifted towards starting at night.
Maybe it could be more like 80% for it to start beeping in the night and 20% it starts during other times.
