NiMH 10cell 600mAH???? the battery said 650 so could I use 700 or is it safer to use 600 because you can not select 650.
chg current: 0.4A ?? I think this is right.
dchg current:???
peak sens: ???
dchg volt:???
trickle curr:???
cut-off temp: ???
no. of cycles: ???
cycle delay:???
cycle mode:???
max chg capa:???
peak delay:???
top-off chg:???


I'll take another whack at it so that you can decide your own settings and why to set them

mah is used as a safety to prevent overcharged multiplied by the max charge % so if using a relatively efficient rate (1C) then the total can be right at 100 % of battery capacity. I like to start with a completely dead battery, set this value very high and then from then on you know what the max capacity actually is and can set the value to that figure. Your 650 may take anywhere from 600-800 when charged fast, but when charged slower (more loss) then it could read over 1000mah.

Charge current for nimh is usually 1C max for small batts, but not always some AA charge at 4C (go figure) I think for your application I would regularly charge at .6 amps and keep watch on batt temp. If it's getting over 120 then reduce rate, if it stays very cool then you can increase rate.

Peak sensitivity for tiny nimh batts is 3 mv and you should experiment with the zero peak setting (I wish there was 1 and 2 mv setting)

Cut-off temp can be 120 deg F in summer and 100 in winter.

Number of cycles is however many you want to examine and cycle delay is designed to allow the battery to cool down and stabilise voltage between cycles. On a very aggressive discharge and/or charge cycle a delay of over 10 minutes is in order, on a very gentle discharge and charge just a minute is enough.

Peak delay is a setting that "cancels" the peak detection for the beginning of the charge so the voltage will smooth out and 3-5 minutes is adequate in most all batts. New or very old or ones that sat a long time would need more delay.
