I see that some are still under the impression that NiCad has a memory in the way we are using them here, not true. Now both NiCad and NiMh do have the problem with voltage depression (note NiMh is not immune from this same problem) which many mistake for memory. This myth about memory has been around for several decades based on the erroneous interpretation of the results of some of the early satellite problems and just won't die no matter hard or complete the chemist's and physicist's explanations are.
Correct, not memory, but crystalline formation:
