Wasn't he actually quoting from Wikipedia?
In any case, this wasn't so much about charger performance but about servo current draw.
My point was that high capacity AA cells, in the main, are not intended for high current applications and I know from my own work with them that high currents and/or deep discharges will degrade AA cells in a very short time. For instance, I have logged a 20% reduction in capacity after 2 discharges at 0.5C to 0.25V from one (mainstream) manufacturer's type.
