NiCads a

a. Horrible for the enviornment (that's the Cad part of NiCad)
b. Have a lousy self-discharge characteristic
c. Are relatively expensive.

NiMH a

a. Not too harmful of Mother Nature
b. Have a fairly decent self-discharge characteristic
c. Are relatively inexpensive (check out thomasdistributing.com)

You may also look into a LiIon pack, depending on which radio you buy.
THey are even better than NiMH.

And using rechargeable NiCad's


Well, it's pretty hard to whistle any praises for NiCad batteries. I dunno
about the environmental issue, which could just possibly be overblown, but
the combination of self discharge and the possibly misnamed "memory"
charastic (when floated on a charging supply) are so bad as make any
environmental impact trivial. After all, who would buy or use one today
when much better choices are available.

As to NiMH, I am just not sold on them for occasional use products that have
to work when needed. As a real estate agent, I am simply stuck with one of
them, in the form of an electronic access key for the "secure" keysafes that
we are no using; but I damned well do not have to like it or think that they
are really a good product. My complaint is that the NiMH batteries are
temperature sensitive, and a missive was recently circulated demanding that
the devices not be left inside an automobile because of the damage that
[would] occur. In fact, to the best of my recollection, NiMH will discharge
in less than a month of disuse unless it is kept refrigerated.

Admittedly, NiMH seems to work acceptably in mild parallel hybrid
automobiles--at least if they are used almost daily. But LiIon certainly
appear to be the future!
