If your alarm is hardwired into your home's electrical system, replace the backup battery at least every 6 months and replace the smoke alarm itself once every 10 years.
Hardwired smoke detectors are connected directly to your home's electrical system and typically do not require batteries for their primary function of detecting smoke. However, many hardwired models also include a backup battery to ensure they continue to operate during a power outage.
Testing and Changing Your Smoke Detector Batteries

Hard wired smoke alarms are mains-powered and include a battery as a backup in case of a power failure. As it's unlikely that both the power and battery will fail at the same time, hard wired smoke alarms offer an extremely reliable form of protection.
Several common causes can explain why your hard-wired smoke detector is beeping: Low battery: Even hard-wired smoke alarms have backup batteries that need replacing periodically. A low battery can cause that annoying beeping sound. Dust buildup: Dust and debris inside the smoke detector can trigger false alarms.
Electromagnetic interference can affect the operations of your fire alarm system by making it randomly go off.

AA Batteries. 9V has been the battery of choice for smoke alarms for many years. However, nowadays, a more common smoke detector battery is two or three AA's.
A hard-wired smoke detector usually chirps because of 1 of these 3 problems: A dead backup battery. Dust inside your detector. Malfunctioning/old detector.
Lithium batteries (non-rechargeable): Lithium batteries typically last 10-15 years if stored correctly, with minimal self-discharge.
This chirping happens every 30 to 60 seconds for at least seven days. When you hear this, it means the battery needs replacing.
