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.
