When it’s time to spring forward and change the clocks on March 14, it’s recommended that you also change the batteries in all of your smoke alarms— it could save your life.
Having a working smoke alarm reduces a person’s chance of dying in a fire by half. For the best protection, install smoke alarms on every level of your home, outside every sleeping area and in every bedroom. Smoke alarms should be mounted high on walls or ceilings, and tested monthly.
Replace smoke alarm batteries once a year, unless they’re 10-year lithium batteries. Even if your smoke alarms are hardwired, replace the batteries in case of a power outage.
