Thanks Ed,

Lots of useful information - I normally cycle/discharge the nicads
every couple of months - looks like I want to space that out for the
NMIH - I did not realize that they had so much less charge/discharge
endurance (a fact that the manufacturers seem to have forgotten to
mention in their comparisons).
