I may never change a smoke detector battery again. These are from Kidde (not sponsored) and they have a sealed battery with a 10 year life!! Very exciting. Only problem is now I see how dingy our ceilings look against the new bright white plastic. I hate painting ceilings. #house #home #safety #smoke #smokedetector #fire #firesafety #diy #doityourself #handyman #homeimprovement Kidde Fire Safety | RLLWoodworks and DIY
