But.. does the mythical A battery exist?
-
Every battery is a battery.
-
Most "batteries" are in fact cells.
-
A battery has many faces. A battery has no name.
-
-
It would appear

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.

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.
-
There are six of these in some 9V piles
-
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

wacom stylus!

I despise and ignore battery powered electronics that don't need 18650s. And i use Arch, BTW. :p
-
It's what 9v batteries are made of. 6 AAAA batteries in a box.
-
Some are. Others are stacked like this:
-
-
I had a pen and pad that copied what it wrote onto a palm pilot that used these.
-
Every single 9 volt battery you've used and original Surface Pen.
-
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.
-
The stylus on a surface pro 7 uses one.
-
These are common in Microsoft Surface stylus and my Kobo Elipsa pen uses them but I'd never heard of them until 2021.
-
Obligatory AA AAA AAAA
-
Any device that it fits...it's still just 1.5v battery.
There is no difference between AA, or AAA and apparently AAAA other then size.
-
There is a difference other that size: capacity

Wait until you see this:
https://brokensecrets.com/2010/12/20/9-volt-batteries-contain-6-aaaa-batteries/
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
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 )
