This is illustrated in the “NiMH Charge curve” figure. The battery is rapidly charged at constant-current, at a high rate of “1C”. After the battery is fully charged, and as it begins to overcharge, the voltage polarity of the electrodes inside the battery will begin to reverse, and this will cause the battery voltage to decrease slightly.
