How do you know when your smoke detector needs new battery?
Common Reasons for Smoke Alarms Chirping:

- Battery is There but Part of the Terminal is Obstructed.
- Another Device or Appliance.
Will a smoke detector go off if the battery is low?

How often should batteries in smoke detectors be replaced?

Test the alarm monthly. Replace the batteries at least once every year. Replace the entire smoke alarm every 10 years.
How long do batteries last in a smoke detector?
Most smoke alarms have a lifespan of eight to 10 years, and again, replace the batteries every year. A smoke detector with a lithium battery or a hard-wired smoke detector can last 10 years, at which time you would just replace the whole unit.

The Smoke Alarm Is Chirping
When that battery is getting low, the alarm chirps to let you know. It’s important not to ignore the chirping; that’s why it’s so annoying. If you ignore it long enough, it will stop because the battery is dead and you’re no longer protected.
Why is my smoke alarm chirping if it’s hard wired?
Most hard-wired smoke detectors include a 9-volt backup battery that’s supposed to kick in if your home loses electricity. If that battery is running low, your detector alerts you with a high-pitched beep. Remove the old battery and replace it with a new one. Press the “test” button and listen for a beep.
Why do smoke alarms chirp in the middle of the night?
Most smoke detectors operate on batteries or have a backup battery. When these batteries fall below a certain voltage, the detector warns us by chirping. This results in reduced electrical output, so the detector is simply telling you that the battery is nearly dead. As we all know temperatures drop during the night.
How long does a smoke detector beep when battery is low?
The battery may need to be replaced. An alarm will chirp every 30 to 60 seconds for a minimum of seven days. The alarm may be malfunctioning.
