I had a craftsman 14.4v cordless drill that was in good shape except
for the ni-cads losing their charge capacity. I jolted each one of
the cells a few years ago and got great results at that time. Now
that the problem resurfaced...I tried it again with no luck. Since
NiMH cells were available, I decided to replace all the cells with
these. For some reason both of the two packs never seem to get much
of a charge. Is there something special these type packs need in
terms of charging? Or is there something inherently missing by using
a nicad charger on a NiMH battery pack?


Sounds like your charger is on the blink, and there was nothing wrong with your NiCd pack...


IIRC nickel hydride cells don't have the peak capacity of a similar NiCd, so they're not as well suited to things like drills, where you need lots and lots of torque for brief periods.
