How to Check & Test Your Smoke Detector Batteries

Kenneth Hellevang, a Professional Engineer of the North Dakota State University NDSU Extension Service, says to "Test smoke detectors at least every three months and replace batteries as recommended," in his article "Keep Your Home Healthy". To be safe, especially during the colder months when heating elements are being used, it is even advised to check them on a monthly basis.

It is easy to test if your smoke detector batteries are working properly and frequent testing done not significantly reduce a battery's power. To do this, simply press the test button located on the smoke detector. Hold for a few seconds and you should hear it go off, like it would in a fire, if it is working properly. If it doesn't it is time to replace the battery.

Other Fire Safety Precautions for Smoke Alarms:
Most alarms use a standard and common 9 volt battery. Make sure to clean the detector when you replace the battery and in between changes as well. To clean the unit, refer to your manufacturer's instructions and/or use a vacuum cleaner to remove any dust particles that may have built up. If the battery is getting low, most smoke alarms make a chirping sound to notify you of the issue. Replace the battery immediately.

The Health Library from the Southwestern Medical Center in "Preventing Burn Injuries" says to not only "clean your smoke detector often." but also that "Smoke detector batteries should be changed twice a year. Choose two dates that are easy to remember such as when you change your clocks, or on a summer or winter holiday." To be safe, do this regardless if you feel the testing works or not.

The Tuscon Fire Department's website states that "According to the National Fire Protection Association (NFPA), minimum protection requires a smoke detector outside each sleeping area and on every level of the home, including the basement." I personally feel that there is no overkill in this area. For extra safety, place a smoke detector in every room of your home to ensure ample warning of a fire. This includes outside of each bedroom in hallways and in entryways and stair landings.
