10-Year Sealed Battery Alarms
10-year sealed battery alarms are powered by sealed, long-life lithium batteries for 10 years, 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 per day, seven days per week for 10 years – that's a decade of hassle-free protection.
