I have Eneloops, Ray-O-Vac "Hybrid", and Duracell Low-Self-Discharge
batteries, and love them all. My children (and the rest of my family,
including me...) go through a lot of batteries, so I sprang for the best
charger (Just an opinion, there are other very good ones out there) - the
Ansmann Energy 16 (Paid $119 at Amazon.com) If you're just interested in
charging just AA's and AAA's, I think the LaCrosse BC-900 is a much better
choice (tells you actual maH accumulated charge!) for much less ($40 at
Amazon, free shipping) and comes with 4 each (total 8) AA and AAA batteries,
plus other accessories. It has features even my Ansmann does not, like
user-selectable charge rates, and a test mode with actual battery capacity
readout on a digital display. I haven't used one, but the reviews seem to
indicate that people are very happy with it.

If you don't want to spend the extra money on a good charger, I would
recommend you have extra batteries on hand, so you can switch them out when
one set is dead in your device(s), and charge only completely dead batteries
for only the time recommended by your charger for your capacity batteries.
As long as you're diligent in taking them off charge when they are done, and
are not trying to charge only "partially dead" batteries, you should be o.k.
Regardless of how they are charged, LSD batteries beat the pants off
"conventional" Nimh and Nicads - I use 'em in nearly everything. Circuit
City has been closing these out (eneloop) real cheap, like $6.00 for 4 AAs
or AAAs - I cleaned my store out - I can't imagine why they don't intend to
stock these any more. I don't think they marketed them properly in the
stores to explain to people what their advantages are.

Anyone have this system?

I really don't use a LOT of batteries but the idea of
throwing them away bothers me as we have no way to
recycle them here locally

I'm wondering if they would work ok in graphing
calculator?

Sorry to post here but didn't know where else to put
it.
Also, is there any diff between a cheap $13 Kodak NiMH
charger and more expensive $40 one?
