    Default Why does the smoke alarm 🚨 battery decide to die at 3:00 AM?

    With an ear piercing screech and proclaiming in a HAL like voice "Low Battery" You know it's futile but still you try to turn over and try to ignore it, but in a predictable interval it starts all over again. Until you are forced to get in your car and drive to the 24hr CVS and buy the silly 9V battery that you can't find in the junk draw.

    All this and the damn thing is hardwired, why does it need a battery anyway ?

    Our new house is just over a year and a half old and all five smoke detectors needed new batteries within a two week period - yep, every damn time they died and started beeping between one and four AM. Sometimes I had a battery but often needed to carry a ladder upstairs while half awake and disconnect the electrical wiring. I've got a twelve pack of nine volts now!

    Plus, it's not so easy to figure out just where the sound is coming from, which of the many detectors in the house needs the new battery.

    The reason for a battery in a hard wired detector is so that it works in case the fire takes out the power or a fire starts during a power outage.

    Murphy's law, of course, the same reason the probably of the toast falling jelly-side down is proportional to the difficulty of cleaning the carpet.

    There are special extra-long-life 9V smoke detector batteries, but that mainly ensures you're less likely to have an extra one when it starts beeping in the middle of the night.

    Because it can?

    Be thankful. Now you have a fresh battery in the thing. You may be very happy about that with the current conditions out there. Be safe. Check them all.

    .... and some (most) houses - mine is 10 years old - have them networked together - if one alarms, they all sound

    One morning at 3, I was awakened by the sound of a smoke detector 3 doors down the street.

    I walked out into the back yard in my robe, and found my neighbor, similarly dressed, standing in his back yard.

    We conferred briefly as to the circumstances . . . This thing was LOUD, and there seemed to be no activity/fire/calamity at the house in question, so I took it upon myself to walk down there and check it out.

    I detoured through the shop, on my way, and armed myself with a 22 oz. Estwing, because you never know what sort of lunatic you may encounter in Hyde Park at 3 AM.



    When I arrived at the back porch of the house in question, it became clear that some tenant/college kid had been out on the town and had come home to crash.

    Then, the alarm went off, and Ol' Gooberhead didn't have the intellectual horsepower at his/her disposal to pull the battery out of the device, but HAD, indeed, managed to get it off the ceiling intact, lay it on the back porch railing, and go back inside to try and sleep off the effects of Saturday night/Sunday morning.



    It was at that point I repeatedly introduced the smoke detector to my little friend, the Estwing 22.




    And peace was restored to the valley.



    The End.

    They have lithium 10 year batteries in smoke detectors now. But I find that changing the batteries once a year is sufficient to prevent unwanted noise. So I use the 2 for $10 smoke detectors and replace them every couple years.

    Good idea to simply replace all of your batteries each fall. Pre-emptive strike.
    There's a lot of things they didn't tell me when I signed on with this outfit....

    Change the clocks, change the batteries.

    For you civilized folks without DST? Every six months, or so. Donít be cheap about THIS!

    It's colder. The battery is less efficient when it's colder, same as you car battery in winter. So that's when it drops below the set parameters.

    I did say night soil, and I did stipulate candle power.

    Plus, who doesnít like panini? Even post-apocalyptic trash panda and purslane panini.

    I do it every spring, when we change the clocks. Daylight Savings Time is also my cue to put the screens on the windows, open the crawlspace vents, clean the dryer vent, clean the air-conditioner returns, and vacuum the coils of the refrigerator.

    Even worse when you replace the battery and then it goes off again after a little while. That means it needs the dust blown out, or something is broke, possibly due to radioactive decay of the Californium inside (this sounds like first class BS Joe but I SWEAR I am not lying). *google* No, wait, it's americium-241.

    Ours went off last week: 0400, 0430, 0500. We have 5 in the house. The clue to the faulty one? The spider crawled out. It's always the last one you check.
