On Sunday, March 8, 2026, most states across the United States will turn their clocks forward for Daylight Saving Time. This seasonal time change is also a good reminder to check the smoke alarms in your home.
Working smoke alarms provide critical early warning in the event of a fire. Taking a few minutes to test your alarms and replace batteries when needed can help keep your family safe.
Smoke Alarm Battery Information
Smoke alarms come in several different designs, and the type of battery they use may vary depending on the model.
When replacing batteries, always follow the manufacturer’s instructions printed on the back of the alarm or included with the device. Using the recommended battery type helps ensure the alarm operates properly.
Many major smoke alarm manufacturers recommend using alkaline batteries rather than rechargeable batteries, since rechargeable batteries may not provide consistent power for smoke alarms.

Important Smoke Alarm Safety Reminders
No matter which manufacturer produced your smoke alarm, it is important to make sure it is working properly. Use the start of Daylight Saving Time as a reminder to test your alarms and change the batteries if needed.
Smoke alarms do not last forever. Most manufacturers recommend replacing the entire smoke alarm every 10 years. Check the date of manufacture printed on the back of the unit and replace the alarm if it is more than ten years old.
Where Smoke Alarms Should Be Installed
For the best protection, smoke alarms should be installed:
- Inside every sleeping area
- Outside each sleeping area
- On every level of the home, including the basement
Testing and maintaining your smoke alarms regularly helps ensure they will work when you need them most.
