Do You Really Have to Replace Your Smoke Alarm Batteries

Do You Really Have to Replace Your Smoke Alarm Batteries?


"CHANGE YOUR CLOCK, CHANGE YOUR BATTERIES"


There is an exception to the every-year rule.  Never change a battery with s ome of the newer smoke alarms that have a sealed lithium power supply that lasts the life of the alarm, 10 years. If your alarms have no visible battery compartment, this must be what you have. 10-Year sealed lithium batteries eliminate those annoying late night battery chirps and save you about $40 in battery costs over the life of the alarm.


10-YEAR SEALED-IN LITHIUM BATTERIES


Kidde now offers a series of smoke and combination smoke & carbon monoxide alarms that contain 10-year sealed-in lithium batteries and come in both battery operated and 120V hardwired (with 10-year battery backup) versions. This sealed-in Lithium Battery eliminates the hassle of battery replacement over the 10 year life of the  alarm. You no longer have to worry about battery removal or unauthorized deactivation of alarm. 


WHEN YOU SHOULD GET A NEW SMOKE DETECTOR

Check the back of your smoke detector for the date it was manufactured. As a rule of thumb, if it is 10 years old - replace it. The sensors in the smoke detectors become less sensitive over time. According to the United States Fire Administration, how often you test and change your home’s smoke detectors depends on the smoke detector you have in your home. Across the board, you should test  your alarms monthly. Kidde Intelligent Alarms offer an  End of Life Warning: which indicates the alarm is in need of replacement.

 

Smoke alarm powered by a nine-volt battery

  • Test the alarm monthly.
  • Replace the batteries at least once every year.
  • Replace the entire smoke alarm every 10 years.


Smoke alarm powered by a 10-year lithium (or “long-life”) battery

  • Test the alarm monthly.
  • Since you cannot (and should not) replace the lithium battery, replace the entire smoke alarm according to the manufacturer’s instructions.
