Hi, Steve

The best to do is charge the cells and let them aside for two or three days ...

Then you measure.

A bad cell will give LOWER voltage than others during discharging ... even invert its polarities ...

And remember NiMh internal resistance can vary a lot with discharge state or rest ( moreover the AA and AAA " High capacity " cells !!! )

C Size do not show a huge variation ... THEM.
