but never exceed .1C ( .1 times ( 1/10 ) the capacity or no more than 1.65 amps for your pack of choice) charge rate.
You are doing just fine.

CG, actually 1.65 amps into a 1650 mah pack is 1C, not 1/10 C. I typically charge my Nimh batteries at 1/4C, which would be about 400 ma for the pack the OP had in mind. On another note, I have found that new Nimh packs take several charge/discharge cycles before they reach their full capacity.
