AAs Batteries. 9V has been the battery of choice for smoke alarms for many years. However, nowadays, it is more common to see two or three AA’s in smoke detectors. AA batteries have about three times as much energy as a 9V.

Most alarm manufacturers recommend against using rechargeable batteries to power a smoke alarm. Smoke alarms that are not hard-wired into your home’s electrical system get power in one of two ways: a built-in battery designed to last up to 10 years, or a disposable 9-volt battery that you should replace once a year.
How long should a 9-volt battery last in a smoke detector?
10 years
These detectors require you to change out your batteries once every year or so. After they hit the 8-year mark you should consider replacing it. A 9-volt battery detector can live up to 10 years if you take care of it. Long-life battery smoke detectors use lithium batteries to power them.
