What device even uses this??
These are common in Microsoft Surface stylus and my Kobo Elipsa pen uses them but I'd never heard of them until 2021.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.

Rule 2- Your post subject cannot be illegal or NSFW material.
Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding non-TIL posts.
Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.
Rule 7- You can't harass or disturb other members.
If you vocally harass or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
For further explanation, clarification and feedback about this rule, you may follow this link.
Rule 8- All comments should try to stay relevant to their parent content.

Is this what Ubisoft is using to power their development??
Old laser pointers used to use quad-As
Old ones
But.. does the mythical A battery exist?
It would appear ~~so~~ not.
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.
BRB
Honestly it feels like "1/2AA Battery" should just be an "A battery"
Ah - so I need to put the drawing on Wikipedia. Noted!
Anything else that’s needed? Quickly please as I’ve already called NYT and CNN
You could read the text next to it. They have an official specification, and they're occasionally used as cells in larger battery packs, but they never got adopted in consumer products, so you can't just buy an off the shelf A battery. Nobody has bothered to get a picture of one, because nobody actually cares that much.

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.)

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.
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.
You could say the same about C and D batteries too.
They're all 1.5V
Yup

There is a difference other that size: capacity
There’s a difference in capacity between AA batteries too. So size then..
.
I remember when I had a surface tablet, the stylus thing used a AAAA battery
