If the smoke alarm is powered by battery, it runs on either a disposable 9-volt battery or a non-replaceable 10-year sealed lithium battery. Alarms that receive their power from your home's electrical system (hardwired alarms) usually have a back-up battery that will need to be replaced once or twice a year.info

10-Year Battery Powered - Carbon Monoxide Alarms
10-year sealed battery alarms offer a variety of benefits to the millions of Americans who rely on continuous battery-powered smoke and carbon monoxide detection in their homes. The alarms are powered by sealed, long-life lithium batteries for 10 years (the life of the alarm), meaning they are always on. With a sealed, long-life lithium battery CO alarm, homeowners can enjoy peace of mind knowing that their homes' CO alarms are always on – operating 24 hours a day, seven days a week for 10 years. That's a decade of hassle-free protection.
