Do smoke alarms need special batteries?
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 AAs. AA batteries have about three times as much energy as a 9V.
Does fire alarm work without battery?
Smoke Alarm Power Sources
Some are battery powered, with either a 9-volt battery or a 10-year lithium battery. Without the battery, neither of these units has the power to go off. Other smoke detectors get hardwired, meaning they tap into and draw their power from the home or building’s electricity.
How long will a 9V lithium battery last in a smoke detector?
The 9-volt battery in smoke detectors has a lifespan of six months if properly used. Long-life battery smoke detectors last up to 10 years before they need a replacement.
