What is the maximum service life of a lithium smoke alarm?

The maximum service life of a lithium smoke alarm is typically set at 10 years. This is based on safety standards and manufacturers' guidelines, as lithium batteries integrated into smoke alarms are designed to provide reliable power for this duration. After 10 years, the performance of the smoke alarm may degrade, and the sensor may not function as effectively in detecting smoke, which compromises safety.

Smoke alarms are crucial safety devices in homes and buildings, and their reliable functionality must be ensured. Regular maintenance includes testing alarms monthly and replacing them at the recommended intervals, which is a standard practice to ensure that they remain effective in alerting occupants to potential fires. The lifespan of 10 years provides a clear timeline for users to follow, promoting proactive safety measures in fire prevention.
