Mrc Super Brain 989 setup

[lanretsr]

Needless to say I'm not an electrical engineer, my father is and was nice enough to give me a Mrc super Brain 989 and I'm wondering what I should be setting it at to charge my batteries?
I have 3 different types:
6 cell 1900mah nicd
6 cell 4500mah nimh
8 cell 4500mah nimh.
Can anyone help me out on what I should be setting the chargers options as?

There's a general formula for charging batteries. Take the capacity and divide by 1000 to get the charge rate. 1900mah/1000 = 1.9. So you could charge that one at 2 amps. The other two you could charge at 4.5A-5A. That will give you maximum life from your batteries; you'll get the most charge cycles out of them. I believe you can also adjust your mV setting on that charger which is the peak sensitivity. I think a setting somewhere around 3-5mV should get you good results.
