I think I understand now
You do not see that little shark teeth on graph like in the case of Li-Ion
A123 have a such low internal resistance that extra 750mA impuls would not change a momentary voltage at all, while Li-Ion cells will respond noticable.
By the way big inpulses are from pulsing charger
balancing charge is hardly noticable and need close zooming on the graph to be noticed.
