I fully concur.  They seem to work well initially, but managing a set of
them is fraught with peril.  It wouldn't be so bad if there was a "bad
battery" tester.  But there isn't.  So some freak battery that isn't cutting
it gets in your pack, and you can't find it.  But the pack won't work as a
set for long.  There is no way to find the bad one.  I even made a single
battery tester consisting of a motor that would run on 1.5 v, and I still
had a hard time.

It is really too bad.  I think the battery industry is very "bad" in
general, and try to keep competitors out.  So you hear all sorts of FUD when
a new thing comes along, and there is the usual attempts to keep competitors
off shelves.

But here is the real question: Why didn't LEGO make the batteries separate
from the RCX?  Changing batts in a built-up creation is a nightmare.  We
should be able to have a battery pack and just swap it.  Then we could make
a 7-cell NiCd pack to replace the 6 (8.4v vs 9.0) in the RCX, and we could
have several.  I am actually surprised that more people don't discuss this,
and LEGO doesn't recognize the flexibility such modularity would have.  Of
course, they would need to have some kind of female connector.

It's strange to see you describe the "how to find the bad cell" problem with reference to Alkaline cells, then go right on and suggest the use of Ni-Cad battery packs! Ni-Cad battery packs have the same problem that any other type of serial (...) (25 years ago, 18-Nov-99, to lugnet.robotics)
