A Ni-Mh battery, even when has a large number of recharging cycles (life cycles), more than 500 and up to a 1000 cycles, where used according to operational manufacturer guidelines, it fades gradually from its nominal capacity, roughly from initially a 100% of its nominal capacity down to around 84-92% of that capacity when around the 500 recharge cycles mark.
