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.

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

sysop408@sfba.social

@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.

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.

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.

@astrid

lanodan@queer.hacktivis.me

@a1ba @astrid Yeah, while if you fold an AAA battery you… explode I guess.

causeofbsod@wetdry.world

@astrid AAAA is also a battery, just not one commonly used. you are most likely to have handled them in packs of 6 inside 9-volt batteries (although not all 9-volt batteries are constructed like this)

izzie@transgirl.cafe

@astrid@infosec.exchange AAAA is also a battery, unfortunately

zwol@masto.hackers.town

@leeloo @sysop408 @mattdm @kwayk42 yeah, six flat cells. in another branch of the thread someone posted a photo: https://infosec.exchange/@astrid/116045181097859309

Oh. I saw the photo, but didn't realise the stripes were cells

@leeloo that went over my head too.

@astrid if A is so good how come they never made a B DNS Record?

ruawhitepaw@chitter.xyz

@leeloo @astrid On a piano, B# is the same as C, and E# is the same as F. But within music theory they are considered distinct notes, and can have different pitches in some contexts.

@astrid I posted this originally, some credit would be nice.
