As far as Cell A is compared to Cell B and C - yes, it's comparative and it's OK, but for checking datasheet's numbers you need absolute results. If the datasheet tells 2.5V cut-off, then you must discharge down to 2.5V. If it tells "10min pause after charge and 30min pause after discharge" - you must follow the instructions to compare your results with manufacturer's ones.

I'm talking about the material the contacts are made from, not the power of holding the cell. Compare the voltage drop from the cell to Opus' PCB with the same if the contacts were replaced with pure copper ones.
