And yet I’ve used products that did exactly this. Remote control cars use multiple single batteries that are wrapped into one useful mega battery.

Cells. A group is Cells form a battery.

A 9V is a battery of 6 1.5v Cells.

A AA is a 1.5V Cell.

I’m a drummer. I batter things. I don’t have enough brain cells to understand all this technical stuff.

But then you need a special battery for a special product. But I can use AA or AAA batteries in a bunch of stuff. If something needs 6v? They require 4 batteries. If they need 4.5 V they can just use 3.

I mean… if there was really widespread demand for it, you could make something AA-cell sized that is actually two smaller 1.5V cells stacked in series. That’s basically what a 9V battery is, it’s six little 1.5V cells packaged up.

But most things that want 3V or more have enough space to hold two or more AA or AAA cells. So there just hasn’t really been enough demand to make a new widespread size+voltage format for consumer usage.
