Comments:
My 0.5/0.6A measurements are coming up a little high. This is something I already know how to fix but it will make comparison to past tests difficult. I'm more concerned with comparing with the cells I've already tested than trying to match other's results. 1.5 Amp and 3.0 Amp results should be pretty close while 5 Amp results may be a little low.
EDIT: For example, the 0.6A tests here are actually drawing 0.59A. the test for #1 lasted 5.166 hours. that means that the result is 51.66 mAh high, so #1 should be 3048 mAh.
