What can one expect out of the lithium rechargeables? One of my friends, an FLL coach, is reporting that their rechargeables seem to have "memory". Are there technical specs for the rechargeables? (18 years ago, 28-Feb-07, to lugnet.robotics.nxt)

I'm very glad to know you got it working again. Incidently, the '1.02' I was talking about isn't the version number on NXT-G itself, but on the USB driver it uses.
