Why Does My Smoke Detector Chirp at Night?
It’s probably happened to you at some point – your peaceful sleep was
interrupted by the piercing chirp of one of your smoke detectors. Obviously,
it’s good to know your smoke detectors are still in working order, but the
alert couldn’t come at a worse time. Why does it seem that your smoke
detector keeps going off at night only? Believe it or not, there’s a
scientific reason for this, and it has to do with your smoke detector
battery.
Battery Basics
Your smoke detector battery is most likely an alkaline battery, which
produces electrical energy via a chemical reaction between zinc metal and
manganese dioxide. Like most chemical reactions, this process can be
affected by temperature. Even when they’re not placed into a device and
providing a circuit with electricity, batteries stored at room temperature
will self-discharge and lose a little less than two percent of their power
per year. However, this number jumps up to five percent at 85° F, and a
whopping 25 percent at 100° F. This is why it’s recommended that you store
alkaline batteries in your freezer, but only if you live in an especially
hot climate.
Similarly, temperature affects batteries once they’re installed and
supplying electricity to devices. A battery at room temperature will
discharge optimally, but one that’s been exposed to cold temperatures will
have a weaker voltage output. As a rule of thumb, just remember that colder
temperatures are good for storage and bad for performance, while warmer
temperatures are bad for storage and good for performance.
Why Nighttime?
Now that you know the science behind batteries and temperature, this brings
us back to the issue of a smoke detector chirping at the worst possible time
. Nighttime is obviously cooler than the day, and the temperature gap
between the two depends on factors like your geographical location and the
time of year. If the temperature drop is steep enough and your smoke
detector battery is already losing power, this can result in a slight drop
in voltage that is just barely significant enough to result in a low battery
alarm. So while it may seem like your smoke detector has been programmed to
disturb your sleep, it’s really just a simple chemical reaction being
affected by the heat of your house.
