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 haven’t disassembled 50 batteries in the last 2 minutes
I reject your edit and substitute the original assumption

How many batteries can you disassemble in 2 minutes? I'm starting the timer.... NOW! Go!
Some have stacked flat cells IIRC.
The carbon-zinc ones never do, but the alkaline ones do, the ones I opened, anyways ( a few decades ago )

But.. does the mythical A battery exist?
Every battery is a battery.
A battery has many faces. A battery has no name.
It would appear ~~so~~ not.
An A battery is usually just called a 17500. They were used in laptop batteries and such but are now used in hobbies more. Mostly for flashlights, vapes, or Lightsaber replicas.
Right - so that is a photo of an AA battery and a drawing of an A battery.
So if I take a photo of a gorilla and draw Sasquatch next to it I have proof of Sasquatch! This is good info to me.

An AA battery next to a dimensioned 2D drawing of an A battery (7mm grid).
(This is an placeholder image for A battery section of en:List_of_battery_sizes. To be replaced with an actual example as soon as one comes along.)

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.
microsoft surface pen is my touchstone for this. the only way i could get new batteries was online and the pen lasted for so long if i bought a pack of 4 batteries i’d have lost the other two but the time they ran or so id need to but a whole new pack.
I'm fairly certain you can take apart most 9 volt batteries to get at the AAAA batteries inside

There are six of these in some 9V piles
Which was the secret knowledge for those of us with pen lights or active stylii back in the day that required AAAA cells. And then you'd find a cheap brand of 9v that actually had a stack of nonstandard square cells inside it instead... Bastards.

I remember when I had a surface tablet, the stylus thing used a AAAA battery
Save money buying just 1 AAAA battery and cutting it in half for two AA batteries.
I think they follow Hydra rules, if you cut it in half you end up with an AAAAAAAA battery

It's what 9v batteries are made of. 6 AAAA batteries in a box.
Some are. Others are stacked like this:
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.

it looks like batteries are screaming like AAAAAAAAA
I use them in my active pens.
I had a pen and pad that copied what it wrote onto a palm pilot that used these.
I despise and ignore battery powered electronics that don't need 18650s. And i use Arch, BTW. :p

wacom stylus!
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.
Wouldn't it be cheaper to replace the flashlight then?
the internet has ruined me.
i've seen flashlight twice and keep reading it as fleshlight, and wondering what fleshlight requires batteries.

Is this what Ubisoft is using to power their development??
These are common in Microsoft Surface stylus and my Kobo Elipsa pen uses them but I'd never heard of them until 2021.
