I hear the low-battery ‘chirp’ and the battery is new?

Question

I just put a new battery into my smoke alarm, but it is giving off a low-battery ‘chirp’. Why?

Answer

  • Does your smoke alarm have a silence button?
    If so, the button may have been pressed by mistake. The alarm will now ‘chirp’ once a minute for up to 15 minutes.

  • Are you sure it’s the smoke alarm?
    Other devices have similar low battery chirps or warning tones.

  • Even new batteries may sometimes not be fresh.
    If batteries are stored, especially in cold areas like refrigerators, they lose their charge more quickly. Always check the freshness date on the package when buying new batteries.
