I just gave one of my old calculators from school to my daughter - that Lithium cell in there is still fine. After 30 years. Maybe in reality it's a secret japanese atomic miniature reactor in there, who knows.

content: That second link is troubling. It's a fake news website set up with the same name as a legit science news company.If you look at it, it's completely full of utterly bullshit stories.

content: I saw this some weeks/months ago. It is not total BS, it is early days still and it is a low average power drain. It can be used with a super cap to provide higher current bursts with a low duty cycle. I think the selling point is for low average drain uses where power is not at hand and changing batteries is a PITA. Like smoke detectors... although mine has a 10 year battery in it.

content: Quote from: Haenk on March 31, 2021, 12:42:48 pmThe real reason to think this is BS is because companies now have next to zero incentive to make their products last longer.

content: Quote from: Cyberdragon on April 01, 2021, 08:37:22 pmI am on the second installation of smoke detectors now - the first model did not come with a built-in battery and a 9V Lithium block lasted about 5+ years.A newer model now comes with built-in batteries (I think that's a 3V Lithium one) and is advertised as "10 years of battery life" (unless you test them too many times, with emergency lighting and sirene probably drawing too much current).It seems they got the wattage really, really down. (Maybe waking from sleep every 15 seconds to fire one single LED beam? Didn't test that...)
