This is a shitshow, probably illegal and the “10” years smoke detectors never last more than 6, like i know a German Youtuber did some magic math and testing, the 10 years is even under laboratory conditions basically impossible, in the real world the thing may go off once or twice, and are tested if they work, already taking out at least 1 year of time…

I fucking want my 9V powered smoke detectors back.

But how would they sell more smoke detectors that way?

  Doesn’t the isotope in the detection chamber degrade and needs to be replaced in 10 years anyway?

    most smoke detectors nowadays are optical.

    Both kinds exist. Both have different benefits and drawbacks.
    
    You shouldn’t only be using one type in your house.

    The half life of americium is 432.2 years, so no

    Those detectors are inferior to optic detectors and should not be used any more.

The smoke detectors in my house are hooked up to the main power, but they still take a battery and beep when the battery is dead. I thought the battery was backup, but they die after about 2 years, so it can’t be backup, it must be used for something.

Even the 9V ones didn’t last forever.

I found that out one very exciting morning, when it decided to sing me the song of its people. If you’ve never stumbled down the stairs at 4am looking for a fire with your bollocks flapping about, I heartily recommend it.

  No of course not, but you didn’t need a completely new smoke alarm when the battery is empty.

    The battery was fine. It was the alarm that had degraded to the point that it always “detected” smoke.
    
    Turns out smoke alarms should be replaced every 10 years or so.
