Googling "aaaa cell" found http://www.batterystore.com/Eveready/E96.htm.
That is most certainly not what's inside the last 9V battery I tore open
(granted, that was years ago, but I can't imagine they've changed much).
The 9V was a stack of (6, I guess) flat rectangular shaped cells.
Well, it's been years, but I read something (either a circuit or a
repair for a device with an AAAA battery) that told me to tear open a 9V
to get some AAAA batteries. I didn't need the AAAAs but, being the
curious type, tore one open anyway. It was, in fact, 6 itty bitty
cells, just like a AA only smaller. They were in actual packaging, but
with brown paper, no artwork.
I haven't broken one open in years, so things certainly may have changed
since then.
Interesting. I can swear I found 6 little flat cells stack one on top
of each other (I was a kid; it might have been 30 years ago), but some
more googling found:

whcih certainly supports the AAAA theory! I know what I'm doing this
weekend :-)
