Do you know how old your smoke alarms are? Like many products you use on a daily basis, smoke alarms don’t last forever. Manufacturers recommend that you replace them every 10 years. To check the date your smoke alarm was made, look at the back of the alarm or inside the battery compartment. If it’s time to replace your alarms, consider buying ones with ten-year lithium batteries.
