Oops! You're right, of course, Frank. For some reason, I was thinking of AA
cells, for which 50mA would be an acceptable trickle. You should not exceed
1/10th the ampere-hour rating for trickle charging, so you could go up to
12mA or so for the "shorty" cells in the Olympus pack, which would charge
them in about 14-16 hours.
My turn to disagree -- 2 or 3 mA might take as long as four days to
recharge the pack! In fact, that would barely keep up with the
self-discharge rate of NiMH cells.
