The009 10 Years on average and that is not just the new ones Battery its literally the sensors inside that need to be replaced after 10 years. CO Detectors are usually 9 years. Fire Extinguishers are usually 10 Years. (If never used) Err0r! He was as high as the ceiling is! https://www.twitch.tv/werecatf WereCatf But I don’t see the kite anywhere!
