Formation charge will be 250ma for 14hrs to 16hrs.
Discharge should be at C/5 usually.
This will be 500ma and should last for about 5 hours before dropping to 0.9 volts per cell.

OK, so on a 2500mah NiMH pack the formation charge should be at 250mah/hr? So I would set my charger to charge/discharge at .25?
