Ban on sale of devices with replaceable batteries
A new state law went into effect on April 1 that bans the sale of smoke detectors that require replacement batteries. Instead, the only detectors that can be sold in the state are those with sealed, non-removable lithium batteries or that can be hardwired.
The law passed in 2015 but included a four-year grace period so that manufacturers could sell their inventory of battery-powered detectors. Homeowners and landlords do not have to immediately replace detectors that use replaceable batteries but must do so before selling or renting a home or apartment.
