The Battery in Your Smoke Alarm Matters

Three out of every five homes fire deaths result from fires in homes that do not have smoke alarms installed or the smoke alarms are not working properly. When it comes to your home and family's safety, it’s critical to have functioning smoke detectors and the proper batteries installed. The battery in your smoke alarm should be something that you can rely on. That’s why at First Alert, we recommend a 10-Year Sealed Battery Smoke Alarm.

9V vs. AAs Batteries

9V has been the battery of choice for smoke alarms for many years. However, nowadays, it is more common to see two or three AA’s in smoke detectors. AA batteries have about three times as much energy as a 9V. When using batteries like these, it’s important that you check them consistently and replace your smoke alarm batteries every 6 months. A good reminder is to change your smoke detector batteries every time you change your clock for Daylight Saving Time.

10-Year Sealed Battery Smoke Alarm

In some areas of the country, it is required to have a 10-year sealed battery smoke alarm. Check out our  smoke alarm laws and legislation map for specific requirements for your state. Even if it is not mandated in your area, First Alert highly recommends these smoke detectors. Ten-year alarms contain lithium batteries that last for the life of the alarm, eliminating the need for battery replacements. These alarms also have an end-of-life warning to remind you to replace the smoke alarm after 10 years.
