Carbon Monoxide Alarms with 1 Year Battery Life
1-year battery-life carbon monoxide alarms are effectively replaceable battery carbon monoxide alarms, and therefore good for cost effective protection. They often come with an end of life warning so you know when to replace the battery. However we still recommend you check they battery regularly. If you are worried that you won’t check regularly then we would recommend a sealed-for–life battery option so you have longer protection.
