Lithium long-life batteries do not need to be changed yearly. Changing smoke alarm and CO detector batteries at least once a year is one of the easiest and most effective ways to reduce home fire deaths and CO poisoning. In fact, working smoke alarms can cut the risk of dying in a home fire nearly in half by providing an early warning and critical extra seconds to escape.
Every home in Seattle should have the protection of smoke/CO alarms. The Seattle Fire Department can install combination smoke/CO alarms and batteries free of charge in homes where the homeowner is either a senior citizen, living on a low income, or has a disability. If you live outside the city of Seattle, please contact your local Fire Department to request assistance. To request an installation call (206) 386-1337 or email firstname.lastname@example.org.
