Yes, 10-year smoke alarms are designed to last 10 years. They are powered by a non-replaceable sealed lithium battery designed to provide ten years of continuous operation. This means you will not need to replace the battery and the alarm will provide protection throughout the entire 10-year period.
Here is a detailed description put together by anka security for you:
Sealed Battery:
The 10-year smoke alarm uses a sealed lithium battery designed to power the alarm for 10 years.
No Battery Replacement Required:
These alarms are designed to eliminate the need to replace batteries during their 10-year lifespan.
End of Life Warning:
After 10 years, the alarm will typically provide an end-of-life warning, indicating that it is time to replace the entire unit.
Regular Testing:
While this alarm is designed to last 10 years, it is still recommended to test the smoke alarm regularly, such as at least once a year, to ensure that it is working properly.
Importance of Replacement:
Even if the alarm is still working properly after 10 years, it is crucial to replace it because the sensors inside may degrade over time, which may affect their ability to effectively detect smoke.
