A - DNS RecordAA - BatteryAAA - BatteryAAAA - DNS Record

@mattdm yeah that brings up so many questions. So few things use AAAA batteries that most people don't even know they exist.

On the other hand, 9V batteries aren't at all uncommon yet manufacturers will often make 6 AAAA batteries first and then use those to make a single 9V? Wouldn't it be more efficient to make the 9V directly and make fewer AAAA's?

This has been bugging me ever since I learned this.

Apparently this: https://onlinelibrary.wiley.com/doi/10.1002/9781119163824.ch1

(Says a PBS article I found.)

A version I heard years ago:
AA - Anonymous Alcoholics
AAA - American Automobile Association
AAAAA - an organization for those who drive while drunk

I used to have a flashlight that took 4.5V batteries that were actually three A cells in a bigger box. Unlike the 9V ones, which are quite hard to dismantle, these had a top that was very easy to pop off and so you could see the wiring inside.

I've never seen an A cell anywhere outside of these ones, but when I was young you could buy the 4.5V ones in most hardware stores. I haven't looked for one for a very long time, so I've no idea if that's a good thing.

@0x09 @astrid

That is the worst pun in the thread, I applaud you.

@sysop408 @kwayk42 @astrid Indeed! I THINK I remember them being around in Sweden in the 80s or 90s but I can't swear on it. I'm sure I haven't seen one in decades though.

@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 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?

@kwayk42

@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).
