A - DNS RecordAA - BatteryAAA - BatteryAAAA - DNS Record

@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).

@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)

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

@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?

@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.

@sysop408 @astrid @kwayk42 I learnt it when looking for batteries for MS Surface Pen. I searched throu all these stores until...

@astrid That's still ok. Imagine this

@sysop408 @leeloo it's six little plastic tubs glued together. A long time ago I cut one of those open myself, saw the same thing, was confused, and looked up the patent number on the outside of the case
