What Is The Best Smoke Detector Battery

One common question many people ask is what the best smoke alarm battery is. Older smoke detectors use a 9V battery. These are pretty decent batteries that have been the best choice for many years. Nowadays though, its much more common to find smoke detectors that use 23 AA batteries. If you can, you should choose AA batteries for smoke detectors. These AA batteries hold three times more energy than the 9V batteries.

In some areas of the country, youre required to have a 10-year sealed battery for your smoke detectors. These batteries do last an entire decade without having to change them. Even if its not required, everyone can choose to buy a 10-year smoke detector to avoid having to change the batteries frequently. Instead, youll change the smoke detectors after 10 years . These 10-year batteries will make a noise to let you know when its time to buy new detectors.

Dont Change Your Smoke Alarm Batteries Twice A Year

Changing your smoke alarm batteries twice a year is just a waste of batteries. Hereâs why:

  • The alarms in modern houses and apartments are âhardwiredâ , and the battery is just a backup in case the AC power fails. So batteries in those units will last far longer than battery-only units.
  • All of the smoke alarm manuals Iâve reviewed say to replace the batteries when you hear the chirp, and say nothing about replacing twice per year. Even for a battery-operated alarm, âA fresh battery should last for one year under normal operating conditions.â
  • For most alarms, you can use lithium batteries, which last for several years. See the section in Lithium batteries below for caveats.
  • Consider using rechargeable 9V batteries , though know that the alarm manufacturers recommend against it.
