No, you all missed the point.
Jack was talking about the idea of LEGO(r) providing an external NiCad battery
pack solution to certain perceived problem (the difficulty of taking a robot
apart in order to change the batteries in an RCX, Scout, etc.). He said:
"we should be able to have a battery pack and just swap it"
If LEGO(r) did such a thing they would clearly implement the battery pack as a
sealed multi-call unit, like cell phones and laptop computers do. (Why? Because
they already *have* a normal 6-cell battery pack box, and Jack did not suggest
the use of that box, which he obviously could have done)
So I was responding to Jack's ideas with my description of the problems of
multi-cell sealed battery packs.
And Jack, if you want to change your original idea to that of using a battery
box, then why not suggest adding a standard LEGO(r) 4-stud electrical connector
to the RCX and Scout whereby it could be powered by the standard LEGO(r)
battery box?

| Hey, all I want is to have the smallest lightest RCX and that means leaving the batteries out of it. I don't really care how they do the connectors. I even have one of those boxes with the button. I just think power source and power sink should be (...) (25 years ago, 21-Nov-99, to lugnet.robotics)

| I don't know about other rechargables, but bad Ni-Cds can be identified. The charger I use has a test mode which measures the battery's characteristics (perhaps putting a load on it a observing the voltage discharge curve?) and indicates its output (...)
