@astrid AAAA is also a battery! Very uncommon but you can still get some if you know where to look for em! 9V batteries sometimes have six cells slightly smaller than AAAA inside of them, too.

@astrid

since we're all picking nits here, AAA is also an automobile club.

@astrid Expanded version of this, that I posted a while ago:

@astrid or some people's AAU swimming classification, but I never made it out of C

AAAAAAAAAAAAAAAAAAAAAAAAAHHH!!!!

@nettings I've taken one apart and I've seen it myself.

@astrid AAAA is four times A because IPv6 address is four times larger than IPv4

@sysop408 @astrid @kwayk42 oh wow, TIL...
but seriously, packing cylinders like that should be illegal. This is basically maximising the amount of air you can sell to a customer.

@mattdm I'm not sure what I was supposed to be seeing in that article. Would it make more sense if I had a subscription to read the full article?

@sysop408 @mattdm @kwayk42
The chemistry gives 1.5 volts. To make 9 volts, you need six cells in series anyway, though you could use other methods to separate them.

@nettings it's packed really tightly in there. The question I have is how it even makes sense economically to do that.

@astrid @kwayk42

@a1ba @astrid Which annoyingly isn't how it works for batteries (or sheets of paper, like A3 is bigger than A4).

@leeloo ah! OK, now I've got the opposite question. If they're doing it like this because of the chemistry, how do the ones that don't use 6 AAAA batteries do it? Are they just making 6 flat cells packed into a rectangle instead of cylinders?

B# and E#? Those keys are missing on my keyboard.

On the other hand, German speaking countries and areas that got their music theory from Germany tend to use H for the B key, so you can add musical note for H.

@sysop408 @kwayk42

tl;dr The manufacturing process for making layers of things in rolls was already well-established for other things. Now even more so, so there's not any real incentive to retool for something else.

@sysop408 @mattdm @kwayk42
Interesting question, the people who have taken those apart would know.

I'm pretty sure lead acid car batteries put plastic walls between the cells (that chemistry gives 2 volts, so also needs six cells for the 12 volts).

@lanodan
though paper sizes have some logic in them.

If you fold A3 you get A4.
