Why is my Smoke Detector Chirping? | No B.S.🚨
Have you gone noise-blind to that constant chirping? Here's what's happening:
The Cause: 99% of the time, it’s just a low battery.
The Fix: Use a 10-year lithium battery instead so you won't have to replace it for a decade.
Still Chirping?: If the problem persists after a battery change, the sensor has died, and you need to replace the entire unit.
Safety First: A new unit can cost as little as $20.
