Kidde 20SD10 Smoke Detector with 10-Year Battery: Never-change 10-year battery
This Kidde smoke detector is for the homeowner who wants reliable safety without the hassle. It's perfect for busy families who need a set-it-and-forget-it solution, like installing it in the kitchen to avoid false alarms during cooking.
While many focus on fire detection, this device offers peace of mind through minimal maintenance. The 10-year battery means you save time and money, with no annoying chirps to disrupt your sleep. The enhanced sensing technology reduces false alarms, so you won't jump at burnt toast.
