Do smoke detectors need special batteries?
Most smoke alarms use 9-volt alkaline batteries, but some use AA. So if this is the first time you've replaced yours, do open the battery compartments on your units and check before heading to the store. via
How long will a 9 volt battery last in a smoke detector?
If your smoke alarms are powered by a nine-volt battery, the battery should be replaced every 6 months, while the detector itself should be replaced once every 10 years. via
Are there special 9V batteries for smoke detectors?

With the Ultralife 10 Year Battery, state-of-the-art lithium technology keeps your life-saving detector energized for a full 10 years. via
How do I know what battery my smoke alarm needs?
Press and hold the test button on the smoke detector. It can take a few seconds to begin, but a loud, ear-piercing siren should emanate from the smoke detector while the button is pressed. If the sound is weak or nonexistent, replace your batteries. via
Why is my smoke alarm still beeping after I changed the battery?
Newer smoke alarms keep some errors in the processor. The smoke alarm must clear errors after the battery is changed, but it might continue to chirp even after you change the batteries. When this happens, the way to stop the chirping noise is to reset the smoke alarm to manually clear the error from the processor. via
How do you get a smoke alarm to stop chirping without a battery?
If your alarm is still beeping, even without a battery, try taking an air blower (similar to one used for keyboards) and blow inside the alarm's vents. You can also do this while changing the batteries. via
Will taking the battery out of a smoke detector stop the beeping?
Will taking the battery out of a smoke alarm make it stop beeping? Taking the battery out of a smoke alarm will not make it stop beeping. To get the device to stop chirping once the battery has been removed, you must drain this residual charge by holding the test button for 15 seconds. via
Why does my smoke detector battery keep dying?
This is usually caused by the absence of AC power to the smoke alarm. It's likely that the circuit breaker has been tripped or the black wire has become loose in the wire nut, and the smoke alarm is operating exclusively off the battery. via
What are the best batteries for smoke detectors?
What is the best 9V battery for a smoke alarm?
The Duracell Quantum 9V Alkaline Battery is the best 9 volt battery for smoke alarm in terms of durability. Duracell builds robust cells, and the Quantum batteries come with a high-density core ensuring power boosts. via
Can I put a lithium battery in a smoke detector?
Lithium 9Vs aren't recommended for smoke detectors unless you follow a strict battery replacement schedule. Those batteries maintain a high voltage until the end of their usable life, so they provide a much shorter “low battery” warning to alert you that it's time to swap in a fresh one. via
Which 9V batteries last the longest?
Energizer Advanced Lithium 9V Batteries are a great long-lasting choice. The lithium design has a storage life of up to 10 years, and lithium batteries can last up to twice as long as alkaline batteries. via
Why is my smoke alarm chirping if it's hard-wired?
Most hard-wired smoke detectors use a 9-volt battery that is supposed to kick in if your home loses electricity. When that battery is running low, your detector alerts you with a chirp that it's running low. Replacing the battery solves the problem. via
Why is the red light flashing on my smoke detector?
Smoke alarms will make a 'beep' or 'chirping' sound when they have a low battery or are faulty. All smoke Alarms also have a red light that flashes momentarily every 40-60 seconds to visually indicate they are operating. This same red light flashes continuously when the Smoke Alarm has been activated. via
Where should smoke alarms not be placed?
Where the temperatures are regularly below 40°F (4° C) or above 100° F (38° C) including unheated buildings, outdoor rooms, porches, or unfinished attics or basements. In very dusty, dirty, or greasy areas. Do not install a Smoke Alarm directly over the stove or range. via
