Hate tracking down that annoying chirp of a dying smoke alarm battery, taking it off the wall, changing the battery, then getting it back on the wall?  Problem solved with this First Alert Smoke alarm with a 10-year battery.

This alarm features an ionization sensor for smoke detection, which is effective in recognizing smoke from flaming fires such as paper and grease fire.

This is a battery-operated unit.  No messing with house electrical wires that won’t provide you with protection if the power goes out. This unit provides continuous monitoring even if there’s a power failure.

Alarm also features loud 85-decibel alarm, easy mounting bracket, a single test/silence button, and an end-of-life signal so you know when to replace the unit.

Home smoke / fire alarms have a limited life span where periodic replacing is needed to provide you and your family protection, why mess with changing batteries?  The price of those square 9v batteries will far exceed the extra cost during a unit’s lifetime.  Try it out!
