How often should I change the battery in my smoke detector?
It is recommended that you change the batteries in your smoke detector twice a year. An easy way to remember is to change the batteries every spring and fall when you adjust your clocks for time change. "Change your clock, change your battery." If your smoke detector starts making a chirping sound, this is also an indicator that the battery needs to be replaced.
