Hi Michael, Regardless of what rechargable battery you use it must be charged and discharged 4 or 5 times to build the capacity of charge. Once this is done the battery can hold a full charge ie 1800Ma or 2000Ma. Ni-Cd batteries have the memory effect and Ni-Mh do not they are much better but only after 4 or 5 full charges then they are set up. Bob.
