In this short video I compare the sizes of the various 1.5 Volt batteries with each other.
The quad A (AAAA) can be substituted for a triple A (AAA) and perhaps a couple washers, or a small nut may be inserted at the spring end, to make them fit. As the diameter is thinner too, a couple of layers of insulation tape may be put around the battery itself.
As these cells are smaller the Amp hour capacity is less as well, but it can help out to get a TV remote going when no triple A's are around.
I added the AA, C, D and F cells for comparison too.
