The 10-year battery in a smoke detector is designed to last 10 years without the need for battery replacement. This type of battery is a sealed lithium battery, which means it will not need to be replaced throughout the life of the alarm. It is a sealed unit, and after the 10-year life span, you simply replace it with a new one.

Here is a more detailed breakdown:

10-Year Life:

These batteries are specifically designed to provide ten years of continuous power.

No Battery Replacement Required:

Unlike smoke detectors that use traditional batteries, you don’t need to remember to replace the batteries every year.

Peace of Mind:

Knowing that your smoke alarm will provide uninterrupted power for 10 years gives you peace of mind, especially during a power outage.

End of Life Indicator:

The alarm itself will eventually signal when it’s time to replace the entire unit, usually with a chirping sound.
