@astrid @sysop408 @kwayk42 uh...oh wow. TIL

@astrid is there any easy way to tell which ones are or aren't without ripping apart a 9V battery?

I actually didn't even know AAAA batteries existed before I learned about this. I found an old 9V and tore into it as soon as I read about it and that one was indeed made from 6 AAAA batteries.

@kwayk42

@astrid also, a monotonous song

@kwayk42 @astrid A is of course a battery size too, albeit a more uncommon one. Any joke involving DNS is still funny!

@astrid Aaaaaaaaaalmost new Tesla Cybertruck for sale!!!! now quick

@jalager OK, I had no idea the single A battery was a thing.

Also, it's really funny that this battery is apparently so uncommon that they didn't have an actual photo to use on the Wikipedia page for battery sizes so they just drew a 2D representation of it on a piece of graph paper.

Huh. So 9V batteries are _actually_ batteries!

@astrid @scream

@fishidwardrobe AAAAAAAAAAAAAAAAAAHHHHHHHHHHHH

@mattdm yeah that brings up so many questions. So few things use AAAA batteries that most people don't even know they exist.

On the other hand, 9V batteries aren't at all uncommon yet manufacturers will often make 6 AAAA batteries first and then use those to make a single 9V? Wouldn't it be more efficient to make the 9V directly and make fewer AAAA's?

This has been bugging me ever since I learned this.
