Change your Clocks, Change your battery
Original post made by James Art, FPE on Nov 6, 2012
Just a reminder-
When you change your clocks, also change the battery in your smoke detectors, and in your Carbon Monoxide detectors. It can save your life or your loved ones!
Another idea is to write the date it is due again: (write: "Due 11/06/13" ) on a piece of masking tape and put it on the side of the detector so you can tell when! (Don't cover the vents.)
Smoke detectors get old, and should be replaced after 10 years.
