Worry-Free alarms offer a variety of benefits to the millions of Americans who rely on battery powered smoke and carbon monoxide detection in their homes. The battery powered alarms contain a sealed, long-life lithium battery lasting 10 years (the life of the alarm), meaning they are always on. 


This line of alarms uses one battery for the life of the alarm to provide 24/7 fire safety protection, eliminating the hassles of low battery chirps and battery replacement. Additionally, the smoke alarms also have location-based attributes which makes it easy to select the right alarm for the right location in your home. The Worry-Free CO alarms are the first and only UL-listed carbon monoxide alarms proven to provide a decade of protection- up to twice the lifespan in other available alarms.


Kidde developed the Worry-Free line to address common consumer complaints with batteries. A recent survey conducted by Kelton on behalf of Kidde, found millions of American homeowners rank a smoke alarm’s low battery chirp as their number one home fire safety complaint. The National Fire Protection Association (NFPA) cites missing or disconnected batteries as the main reason smoke alarms fail to operate in residential fires.  The NFPA and the National Association of State Fire Marshals (NASFM) recommend for smoke alarms to be powered by 10-year, sealed-in batteries, in an effort to reduce the risks with missing batteries.
