Newbe! I had my 1st 6 flights about 3 weeks ago and I'm charging up for tommorow night

I'm using a converted power supply (11.4v) to feed a hobbyco quick field charger MKll.
I'm charging a NiMH 4.8v 1200mah, battery is in the plane.

Battery indicates 1st charge at 100 - 125 ma for 16 to 20 hours
trickle charge at 25 - 50 ma

what is a " safe " range for charging?
I have over night so I'll set it for 35ma....it should stop charging when its done?

If I was at the field and wanted to " push " it what could I do? charger will do 2.0 amps...

I just started charging:
After 10 minutes the charger beeps 7 times and starts flashing indicating it is going to trickle mode.
Is that short a time normal?

Also when I put a meter in the meter ports what exactly am I reading?
with everything hooked up but turned off I read 5.22v
turn on the PS and charger and I read 5.69v
its been 1 hour and it reads 5.55v

How do I use this info?

I'm going to reread the manual but it doesnt help much

TIA
