@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?

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)
