How long will the smoke detector battery last in my smoke alarm?

Actual battery service life depends on the particular design of your smoke or carbon monoxide detector and the environment in which it is installed. All kinds of detector batteries specified in the users manual are acceptable replacement batteries. Regardless of the manufacturer's suggested battery life, you MUST replace the batteries immediately once the unit starts "chirping" (the "low battery warning").
