What device even uses this??

Every single 9 volt battery you’ve used and original Surface Pen.

I’ve only seen the stack one, but I took apart lots of procells
Wait until you see this:
https://brokensecrets.com/2010/12/20/9-volt-batteries-contain-6-aaaa-batteries/
Could have about 1/3 more charge if they were solid.
Why aren’t they?
Because it’s a 9 volt battery.
Batteries are cylindrical because it’s the most efficient shape to make them in. There is a central electrode with the electrolyte around it. By making it cylindrical it’s distributed evenly. Imagine having it square, then in the corners the layers would be thicker than on the sides.
So that explains why the cells and normal AA batteries are cylinders. So why not have a 9 volt cylinder? That’s because the chemistry used for alkaline batteries produces 1.5 volts. A single cell, regardless of size, only produces 1.5V. So how do you get 9V out of a 1.5V battery? By putting 6 of them in series. 6 x 1.5V = 9V.
That’s a different chemistry that is not as high quality.
I took apart a lot of batteries as a kid. The nine volts never had batteries like this inside them.
Some have stacked flat cells IIRC.
some do, i have dissasembled some of them to look like this. not all of them though
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

How many batteries can you disassemble in 2 minutes? I’m starting the timer… NOW! Go!
I haven’t disassembled 50 batteries in the last 2 minutes
I reject your edit and substitute the original assumption
The carbon-zinc ones never do, but the alkaline ones do, the ones I opened, anyways ( a few decades ago )
And A23 cells have eight LR932 button cells inside
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
I remember needing 4 D batteries for my boombox as a teen. :D
Yup
They even have adapters to convert AA to C or D
There is a difference other that size: capacity
There’s a difference in capacity between AA batteries too. So size then…
.
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.
You can buy a 9v and open the case with some pliers and then boom. You go yourself some AAAAs
Came here to say this. I once cut open a 9-volt battery and discovered it was really just 6 AAAA batteries wired in series.
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.
How else would it light up your penis
Same bro… Same bro and yea I think they got one that does take batteries.
Get yourself a motor from an.old game controller, shove it in the back, wire it to a power source and rock out
man, I’ll just plug in starfox 64 and a rumble pak. thats how we did it in 1998
Whatever gets you through
Just make sure the shaft isn’t to long… Well unless your into power sounding
Verily
Congrats. You’ve successfully made me shudder and flinch with the phrase “power sounding”
If his job required constant use of a flashlight a fully rechargeable one would make the most sense. Faster cheaper better
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”
Where they made by Ubisoft?
They are only sold as a temporary license. Then Ubisoft breaks into your house and takes them away.
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
Hail Hydraaaaaaaa!
wacom stylus!
Is this what Ubisoft is using to power their development??
it looks like batteries are screaming like AAAAAAAAA
Obligatory AA AAA AAAA

Lemmy has bathymetry enthusiasts?
But… does the mythical A battery exist?

That’s preposterous
Every battery is a battery.
Most “batteries” are in fact cells.

Is a battery with one cell still a battery? Is an empty library still a library? Is an empty breadbox still a breadbox?
This is why humans make good batteries.
Humans make terrible batteries, you leave one in a box for 6 months, you come back to a soggy, very stinky box.
Humans are much better as low power space heaters. As long as they have fuel, they’ll maintain a known temperature.
A battery has many faces. A battery has no name.
It would appear
sonot.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.
BRB
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.
Thanks - I’m adding some text now next to the drawing about occasional sightings in Canada, but as they don’t care about capturing it nobody has a picture of it. Hence validating my drawing as the only proof.
No public image at least.
Can someone fix this dire state of knowledge?
Honestly it feels like “1/2AA Battery” should just be an “A battery”

My mistake!
I think you were right, it does exist, but Wikipedia doesn’t have a picture of one they can legally use. For example I found this:
https://www.batteryequivalents.com/a-size-battery-equivalents-and-replacements.html
Funny. I have 3rd-party scripts disabled and it spawns endless search fields.
There’s even C batteries, they were known as baby batteries when I grew up, and quite a few ghetto blasters used them
The stylus on a surface pro 7 uses one.
My old Genius graphics tablet used AAA batteries, as it was from the times when Wacom’s patents on battery-free pens haven’t expired.
Same goes for the kobo libra 2’s stylus
Yep, I bought a pack of these, but then i didn’t need them because I didn’t use the stylus enough/stylus had a good battery life, BUT then when I did want to use the stylus I had no fucking idea where I stored those batteries.
