What is the proper way to charge these cells. I have a number of AA's
that are all weak. I have tried charging them at a constant rate of
about .050A overnight and they seem to come up and they will work but
don't last very long. Can these be charged manually as you would Nicads
or is there a special trick to this? Thanks, Lenny Stein, Barlen

I kinda wish someone would write up the best ideas that work about various
batterys and charging methods, and methods to test each
for quality. In working with NIMH, I have yet to gather enough
information to really evaluate them properly.
I have some that seem to shut down prematurly powering a digital camera.
I think its just one cell acting up or something like that sometimes. I
always wanted to build
a charger, like one charging position for each cell. I never liked
charging them
in series or parallel. Each one should be individually handled.

So far it seems Maha makes chargers that do a pretty good job. They have a
couple that are said to rejuvenate cells - - the MH-C204F and the MH-401FS.
I bought the more expensive MH-401FS because it charges and monitors each
cell individually, and can be set for either 2 hr or 5 hr rate. So far, my
NiMH AA cells are performing well in regular use in a 3-watt Luxeon
flashlight that pulls about an amp out of a pair of Energizer 2300 mAh cells
