As of today, Assembly Bill 3057 (Chapter No. 583) requires that all battery-operated smoke alarms sold within the state include a sealed, non-replaceable battery that’s meant to last for the entire 10-year lifespan of the alarm, according to the PRNewswire.

This requirement applies to any battery-operated device that detects smoke, including combination alarms that detect both smoke and carbon monoxide (CO), according to the New York State Department of Codes.

Battery-operated CO alarms that do not detect smoke are not affected by this new law. In addition, the law does not apply to newer construction homes with hardwired alarms. The law also excludes alarms that connect to a panel, or other devices that use a low-power radio frequency wireless communication signal.

However, all other expired battery-operated alarms that are replaced after April 1 must have a 10-year battery. In addition, homeowners and landlords must upgrade their smoke alarms before selling or renting homes and apartments in New York State.
