I note that the spec show that there is very little to choose between the 2 sizes these days. In the past the 015 was substantially more powerful with a much higher AH and CCA rating than the 038. Whether the 038 rating has risen or the 015 fallen I don't know. Also the 015 used to have a larger physical size but these now look the same.
However, i did just find this 038 battery with these dimensions which are more like the ones I remember.
