@astrid AAAA - Also a battery

9V batteries contain 6 AAAA batteries

@kwayk42 @astrid A is of course a battery size too, albeit a more uncommon one. Any joke involving DNS is still funny!

@jalager OK, I had no idea the single A battery was a thing.

Also, it's really funny that this battery is apparently so uncommon that they didn't have an actual photo to use on the Wikipedia page for battery sizes so they just drew a 2D representation of it on a piece of graph paper.

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.

@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.
