To my environmental shame, I've given up on NiMH for my digital camera,

So have I, again to my shame, because they simply didn't last long enough.

I've found that the cheap plug-in chargers don't charge NiMHs
sufficiently. They use a timer rather than monitoring the state of
charge of the cell. I charge them twice, giving them time to cool down
in between.

New NiMHs also require half a dozen or so full charge/discharge cycles
before they achieve full capacity.
