Cells. He means cells, not batteries. 9V is a battery; anything with more than one cell in a pack is a battery. Anything with a single cell is, well, just a cell. Your 12V automotive battery has six 2V lead-acid cells in it. A 9V has six 1.5V alkaline cells. That 6V lantern battery he mentioned has four 1.5V alkaline cells.
@PocketBrain Yep. I’m visual so a few years ago tore apart a 9-volt battery:
Guessing this six AAAA cells within a case packaging and the resulting duplicate cases might also explain why it is very rare for a 9-volt battery to leak into devices.
Also likely explains why 9-volt batteries tend to be 4-6 times more expensive than individual AA or AAA cells.
Yes.

@PocketBrain @RedOak I thought it’s because they’re rectangular. Like refrigerators.
