NiCads in human use have NEVER had memory issues, NASA has do***ented
memory in orbital satellite use but NEVER in human use, you have to
discharge the battery to EXACTLY the same point many times before it
will have a memory, you simply can not do that (Save for full discharge)
Now: What can happen is a metallic thead can form from the case to the
center conductor (Anode IIRC) This shorts out the battery and makes it
appear as though it's "memorized" a short cycle. A "Zap" (high current
charge) melts this thread (like blowing a fuse) and restores battery
capacity.
Of course the greater the discharge level... The faster this thread
forms.. So the "Always fully discharge it" lobby is likely slitting
their own battery.
