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

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

Inside a 9-Volt Battery

Here is what you will find inside a standard 9V battery... 6 AAAA wired in series!

@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.

[sysop408@sfba.social]

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

@astrid @kwayk42

[lanodan@queer.hacktivis.me]

@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.

@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.

[leeloo@chaosfem.tw]

@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).

[a1ba@suya.place]

@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
