Summary of the Article: Battery Life in Hardwired Smoke Detectors
1. Battery Replacement: If your hardwired smoke detector has a backup battery, it is recommended to replace the battery every 6 months.
2. Smoke Detector Replacement: Additionally, the smoke detector itself should be replaced every 10 years.
3. Power Outage: A power outage can trigger the alarm of a hardwired smoke detector, causing it to sound briefly.
4. Silencing the Alarm: To stop a smoke alarm from beeping during a power outage, you can remove the smoke detector from its mounting bracket, disconnect the power cable, and remove the battery. Pressing the “Test” button for 15 seconds will silence the alarm.
5. Dead Battery: If the smoke alarm has a dead battery, you can press the “Test/Silence” button on the front of the unit to stop the beeping. If that doesn’t work, you can detach the smoke detector from its base and replace the battery.
6. Removing Battery: Taking the battery out of a hardwired smoke alarm will not stop it from beeping. The detector maintains a residual charge that can keep the chirping going for at least seven days.
7. Backup Battery: Hardwired smoke alarms include a backup battery to ensure continued functionality during a power failure.
8. False Alarms: A smoke alarm may go off with no battery or a fading battery, resulting in a false alarm. Checking the battery connection and replacing the batteries can help resolve this issue.
9. Beeping of Hardwired Detectors: To stop a beeping hardwired smoke detector without a battery, it’s recommended to disconnect the power and seek professional assistance.

Why is smoke alarm going off with no battery
Low Battery Life
You may get a false alarm if the battery life is fading or if the detector isn't properly connected. To check the battery, remove the outer casing and check to ensure that the old battery is properly connected. If so, it's a good idea to replace the batteries.
How do you stop a hardwired smoke detector from beeping without battery
Hardwired smoke detectors (which typically include a backup battery) are subject to similar issues as those that operate on a battery only. However, hardwired units often require resetting after problems are addressed. On most, simply hold the reset button for 15 to 20 seconds to silence the noise.
Will a dead smoke alarm eventually stop chirping
A smoke alarm will eventually stop chirping if you do nothing. Once the battery has run out completely, the device will switch to residual power. Eventually, this will also drain and the device won't have enough power to beep and let you know it's out of power. You should change the battery before this happens.
Why do smoke alarm batteries always fail at night
As a smoke alarm's battery nears the end of its life, the amount of power it produces causes an internal resistance. A drop in room temperature increases this resistance, which may impact the battery's ability to deliver the power necessary to operate the unit in an alarm situation.
