The result is not that surprising, one cell is a fairly decent high current cell, the other a high capacity cell and none of them are near the rated capacity.

I forgot to attach the temp sensor on the A cell.

Conclusion
Either cell is fairly decent, but they are definitly not the same and do not live up to the specifications.
I will rate them as bad cells.
