Knowing how to change a smoke alarm battery is essential to maintaining a safe home. If your smoke alarm starts chirping or giving off short beeps, it usually needs a new battery change. The first step in learning how to change a smoke detector battery is determining which type of alarm you have. Battery smoke detectors run solely on batteries. Hardwired smoke detectors run on electricity, but they also have a backup battery for power outages. When you hear a hard-wired smoke detector beeping, it means you need to replace its battery. This Home Depot guide gives instructions on how to change a smoke detector battery and how to turn off a smoke alarm.

What Is The Normal Lifespan Of A Smoke Detector

According to FEMA, a smoke detector should last up to 10 years. After this point, you should replace it with a new unit. Of course, you may decide to upgrade it more frequently. In any case, you should test your alarm once a month and change its batteries at least once a year to keep it in good working order.

Replace Old Smoke Detectors

Sadly, there isnt much you can do once the device is at the end of its life except replace it. The sensors are what start to fail at the end of a smoke detectors life, and you cannot readily replace those.

You can keep ahead of your devices life expectancy by keeping a record of when you first installed it.

Will Taking The Battery Out Of A Smoke Detector Make It Stop Beeping

Kidde Smoke Detector Chirping With New Battery

A battery-operated smoke detector contains a small amount of radioactive material. This material emits alpha particles, which are absorbed by a small plate of metal inside the smoke detector. The absorbed alpha particles cause the metal plate to become electrically charged. When smoke enters the smoke detector, it causes the electrical charge on the metal plate to decrease. This decrease in electrical charge triggers the smoke detector to sound an alarm.

Removing the battery from the smoke detector will not stop the beeping. The only way to stop the beeping is to either remove the smoke detector from its mounting bracket or to press the test button on the smoke detector.

Without that battery, the smoke detector is useless. In fact, even a weak battery in a smoke detector may compromise the operation of the detector. Even electric smoke detectors that are wired into a home’s electrical system are equipped with a battery backup: This means that, even if power is lost, your family and home are still protected.

Why Do Smoke Alarms Chirp Intermittently

The chirp is usually caused by issues related with the battery or miss-wiring. However, dont confuse the chirp with an intermittent alarm. A chirp sounds like a higher pitched tone and sound in equal intervals about once every minute. An intermittent alarm is usually a random sound for several seconds and has a lower pitched tone.

Tips For Changing A Smoke Detector Battery

As already mentioned, there are different ways to how the smoke alarm batteries are fitted into the devices. The main aim of these configurations is to ensure a safe condition by ensuring the detectors are not installed without a battery, and the batteries are fitted properly.

So, when there is a red lever which is a battery reminder finger, you need to press the finger downward then press the battery on top when the battery compartment is empty. Finally, replace the door.

Whenever there is a ribbon, drape it across the empty battery compartment, and the battery should be replaced. This makes it easy to remove the battery and replace it again. However, remember to tuck the ribbon into the compartment and replace the door.

On the other hand, whenever there is a front load door found at the bottom of the detector, you can change the battery without having to remove the mounting bracket. Open the door using your fingernail or butter knife. However, some doors may require you to slide them to the side before you swing them open.

Lastly, when there is a side door, open it and ensure it is extended to its full length. Check for the positive and negative markings on the detectors and ensure the batteries match the batterys markings. Then finally, you slide the door back in place.

Remove The Old Battery

If there were a way to fit both the new batteries and the old ones all at once, I would go for it to avoid any future chirping. Unfortunately, however, both batteries can not fit in simultaneously, and the old has to give way to the new, which is the tragedy of life anyway.

Before you remove the battery, you might want to check the orientation to be sure you will install the next one correctly. Most detectors have a more direct way of installing the batteries, but being sure about it does not hurt. You do not want to get off the ladder or table..wait, how did you get to the ceiling? We must have missed that part. You will need a strong ladder or table to step on to reach the ceiling. If there is someone around to support you, that would be great.

Back to our train of thought. You do not want to get off the ladder or table just to second guess whether you got the connection right. Let ave the second-guessing to locking doors. Once you are sure about the orientation, remove the old battery and install the new batteries. The chirping will be gone. But more importantly, the smoke detector will be fully functional. Also, the annoying chirping will be gone. Don’t you feel like smashing the detector just to shut it up sometimes? I do too, but changing the batteries is the way to go.

This could happen when you are cooking at high heat or someone opens the bathroom door soon after taking a hot shower.

Does your smoke alarm have a separate silence push button? If so, the button could have been pressed by accident. The alarm will then chirp once every minute for up to 15 minutes.

Why Does Your Alarm Go Off In The Middle Of The Night

If your alarm only chirps at night while youre cozy in bed, you may be tempted to believe its messing with you deliberately. However, there is actually a technical explanation for this behavior. The phenomenon is a result of two factors:

  • The batteries in your device are running low.
  • The temperature in your home falls at night. Lower temperatures cause power to drain more quickly from batteries.9

In short, your low batteries dont chirp during the day because they are putting out just enough power. However, if they are weakening at night, they begin to run low and you should replace them.
