Carbon Monoxide Alarms with 7 Years of Battery Life
7-year battery-life carbon monoxide alarms all come with sealed-for-life lithium batteries. These are ideal if you want the peace of mind of a longer life solution. There are options for 5, 6, 7 or 10-year life protection, so you can choose the length of protection that works for you. If you are worried about people taking batteries out for the remote control, or not confident you will check your alarm is in working order regularly, then a sealed-battery option will be best for you.
