Well I'm certainly not a battery engineer by any stretch, but I have yet to discover a battery regardless of materials used that will never (ever) develop a memory to some extent. Seems to me that eliminating the possibility by draining would be more prudent.

However, I would lean to opinions of the experienced. Seeing as I don't not know the amount of yardbird's or Cj's expertise, but have a firm grasp of my own. I go with they say... :)
