In this short video I compare the sizes of the various 1.5 Volt batteries with each other.<br /><br />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.<br /><br />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.<br /><br />I added the AA, C, D and F cells for comparison too.
