The Nimh are generally much higher capacity than their
Nicad cousins and we should expect them to outperform
the Nicads. I use Nimh in my amateur radio hand-helds
and have also noticed improved longevity . . . at least
with respect to usage. Nicad and Nimh have much higher
self-discharge rates than alkalines and therefore have
very poor shelf life by comparison . . . but for gizmos
that are used regularly, the Nimh is an excellent
alternative. I think service life of the Nimh should
be on a par with Nicad.
