we had this same issue a few years ago - we settled on one brand
of replaceable batteries - we went with energizers which we switch out
right before every run during the tournament.
One reason is that the discharge curve drops off pretty severely after a
short while - also the rechargeable batteries have less and less staying
capacity as we go along.
We also run the robot a few times through its program set
before the competition round - takes the edge off the discharge curve.
Here's the AA discharge curve that backs up my thinking:
