When to Change the Batteries in Your Smoke Alarm

The smoke alarms throughout your home help play a crucial role in keeping you and your family safe and alert of potential dangers. However, the best smoke alarms are only as good as the power source that is fueling them. It is important that your home smoke alarms are monitored and tended to as needed in order for them to work properly. If a potentially dangerous situation were to occur in your home, you’ll be happy you checked your smoke alarms!


What Smoke Alarm Do You Have?

The United States Fire Administration notes that the frequency of changing the batteries in your fire alarm depends on the type of smoke detector that you have. At First Alert, we offer products that make this process as easy and straightforward as possible. For example, we offer many 10-year smoke alarms that come with a built-in 10-year battery, which elimates the need for battery replacements for the life of the alarms. We also offer hardwire alarms with battery backup, for protection during power outages.


Testing and Changing the Battery

As a general rule of thumb, even for the best smoke alarms on the market, you should plan to test them at least once a month. If your smoke alarms are powered by a nine-volt battery, they should be replaced at least once annually while the alarm itself should be replaced once every 10 years. For 10-year lithium-powered smoke alarms, you won’t need to replace the battery. Instead, replace the entire alarm after 10 years have passed. If your alarm is hardwired into your home’s electrical system, replace the backup battery at least once per year and replace the smoke alarm itself once every 10 years.


Signs You Need to Replace the Batteries

You’ll likely notice a high-pitched chirping noise coming from your smoke alarm if the batteries need to be changed. It is best to be proactive and change the batteries in your smoke alarms before that noise occurs. When you change the batteries in one alarm, make sure you change the batteries in the rest of the alarms in your home as well.

The best smoke alarms will make you and your family feel protected at all times. Browsethe First Alert website to learn more about smoke alarms or other fire-related equipment such as fire escape ladders, fire extinguishers, disaster and security safes, and more!
