Took a look over the postings on Lugnet, many of which are quite
old and using which I think I could have supported any opinion I
cared to form :-)

Two choices seem to be

a) NiMH. Pros are they are available, can be recharged a lot and
    don't leak. Cons are they start at 1.2V (x6=7.8v) instead of
    starting with the full 9V, so you don't have the fresh out of the
    box power you do with new alkalines. From what I read, they
    too end up at about 1V, just like alkalines.

b) Rechargeable alkalines. Pros, cheap and they start with a full
    1.5 volts, having a discharge curve more like regular batteries,
    ending up down at the 1V mark. Cons, some people have said
    they lose effectiveness greatly with each cycle and, worse, when
    they get old, they start to leak corrosive stuff which does nothing
    good for the RCX.

What's the latest thinking? What are people using?

Roland

I use rechargeable alkalines, Rayovac Renewals, to be exact.  You will be
amazed at how long they last.  I do not wait for them to be fully
discharged.  It turns out that, with 2 sets, I recharge every couple of
months.  So far, they have not degraded in use or leaked gooey stuff.  I
think that warning applied to an older generation of batteries.

I have nothing against NiMH's;  I use them exclusively in my digital camera.
