    Squares have better packing efficiency. But I’m sure they’ll make round versions. Button batteries are circles because they’re so often used in device with round form factors.

      They’re probably used about as often in non-round items than round. They’re ubiquitous for anything that needs a small, constant, relatively long lasting power supply.
