Smoke and carbon monoxide (CO) detectors are widely available with built-in, sealed 10-year lithium batteries, which last for the entire lifespan of the alarm and eliminate the need for frequent battery changes. The entire unit is typically replaced at the end of the 10-year period, as the sensors also degrade over time.
Key Features of 10-Year Battery Detectors
Hassle-Free Power: The sealed lithium battery provides continuous power for a full decade, removing the need for annual or semi-annual battery replacements and eliminating the “low battery chirp” in the middle of the night.
Dual-Sensor Protection: These devices are combination alarms, utilizing both photoelectric sensors (for smoldering fires) and electrochemical sensors (for CO gas detection) to protect against two potentially deadly threats.
End-of-Life Warning: When the alarm reaches the end of its 10-year lifespan, an audible end-of-life signal will sound, letting you know it’s time to replace the entire unit for continued safety.
Various Options: They are available in battery-only powered versions that are easy to install anywhere, or as hardwired units with the 10-year battery serving as a backup during power outages.
Compliance: Many states and local jurisdictions now require the installation of 10-year sealed battery alarms to ensure constant protection. The products are tested to meet safety standards like UL 217 and UL 2034.
