    I have a wacom-type pen for a tablet that uses one of those. It was a total pain in the ass the time I was traveling and accidentally discharged it by jamming the button in a tight-packaged bag. Turns out, they are pretty much only available online. No normal shop ever stocks them, not even electronics shops nor radio shacks. Barely anyone even heard of them. Tried disassembling a few 9V’s, but all of them were the stacked kind. And with international shipping going 2-6 weeks and me changing locations more often than that, it was an extremely difficult to get hold of them.

      When Dan’s Data reviewed these, he said something like “even if you use this in space, you are still no further away from a shop that sells replacements than you would be at home

    I have a flashlight at work that uses them. It’s a PITA because we don’t stock AAAA batteries at work so they have to be special ordered.

    Usually they’re used in thin devices where a bigger battery wouldn’t fit. Lots of computer styluses take AAAA batteries, including the Microsoft Surface Pen. There are also some small flashlights and laser pointers that use them.

      Yeah I bought a 6 pack of them when I bought my pixel slate. They expired after I’d used two

      I took apart a lot of batteries as a kid. The nine volts never had batteries like this inside them.

        Since seeing this picture I have disassembled about 50 nine volts looking for this and have found about 3. Some full of coin cells too.

        Edit: I should say it was years ago I first saw this picture. I haven’t disassembled 50 batteries in the last 2 minutes

          I reject your edit and substitute the original assumption
