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.
