how to use 989 super brain

[diesel1984]

i got a 989 super brain MRC charger today..i read the instructions and still dont really know how to use it.
I have 2 IB4200 9.6v 8 cell packs
and 1 IB1100 5 cell reciever pack

could someone please explain to me how to charge and discharge these the most effectively? i really want to use it tomorrow, but the electronics seem to be smarter than the operator at the moment...:confused:

This was my first charger. If I remember correctly It is very easy. You have 4200's so you could charge at 4.2A I always charged at 3 though. And If they are new packs cylce them a few time first. But I think its just setting it to the Amps and pressing start.

like im asking how to set up the cycle? amps for discharge and charge...im using a Y harness so do i just type in 16 cells or what...

[diesel1984]

also you mean it finds the peak itself so no other tweaking on my part?

[lferguson]

I really don't remember that much. I looked to see if I still had the instructions to refresh my memory but I don't. I do remember the instructions kinda sucked, but once you figureed it out, it was easy.... Sorry

[diesel1984]

yea i get what your saying...the instructions are really complicated...making it harder than it needs to be

[diesel1984]

so i set it to 3 amps for both charge and discharge and set for nimh and 16 cells

[lferguson]

No discharge is to be set lower like 1 I think.. But yes, other than that both posts are correct. Instructions make it something it's not....hard.

[diesel1984]

so its been a long day ok... 16 cells at 3 amps charge,dont set anything else. then 16 cells discharge @ 1 amp

[lferguson]

No, I think you still need to set the discharge also just set it lower. I could be wrong about that part but I think thats the case. Long day here also, don't worry.

[lferguson]

Oh and you can charge at 4.2A, I just liked to pamper my NiMH's.

[lferguson]

Dang it I just read my posts!!! 10A Discharge is what I meant!! 1 will not hurt just take FOREVER! Really sorry about that. 10 discharge. Yes long day.

[diesel1984]

so charge at 3 amps and discharge at 10amps? this is only for the C cell 4200 batteries right?
What about for the IB1100 reciever pack charge at 1.5amps and discharge at 1amp?

[diesel1984]

so discharging the batteries at 10amps will not shorten their life span or is that goonly with charging them with too many amps?

[diesel1984]

for the IB1100 5 cell reciever pack can i just charge at 1.5amps and discharge at 2 amps?
