How the discharge plot of a Ni-Mh compares to a Ni-Cd battery?
The Ni-Mh will show a flatter-longer discharging period, with a very stable 1.2Vwhich is much better than in Ni-Cd or Alkalines where the curve is more uneven during the discharging period. Also the Ni-Mh will die off quicker when it gets to the end of its charged capacity that other batteries, which permits a device to behave better for a longer time.
