This backup battery keeps the smoke alarm powered even in the absence of electricity. This blog will give you some tips on how to stop the chirping noise in your smoke alarm.

Why do smoke alarms keep chirping even when the battery is changed?
Smoke alarms should make a loud chirping noise or shrill beep to warn you that the batteries need changing. If an alarm is beeping or chirping, the first step should be to change the batteries. However, sometimes the smoke alarm will continue to chirp after you change the batteries. This can be frustrating because you think you have changed the batteries correctly and the batteries are working. The smoke alarm might stop chirping after a few minutes, but then it will start chirping again after a few hours.

What causes a smoke alarm to chirp?
Chirping noises are usually signs that your smoke alarm needs to be replaced, but there are some instances when the chirping occurs for other reasons. One instance is when the battery is low. If this happens, the smoke alarm will make a chirping noise to let you know you need to change the battery. Some smoke alarms will continue to make the chirping noise even after you replace the battery. This is because the smoke alarm has detected that there is something wrong with the battery, and it is trying to fix the error. The error is typically cleared once you change the battery, but there are times when the error may not be cleared. The smoke detector will continue to make the chirping noise until the error is manually cleared.
