Novak Equalizer/discharger Q's?

I picked up a Novak equalizer/discharger (#4500) today. It's seems pretty cool. My question is, I put a pack on it and let it discharge per the instructions. I then let the pack cool off before putting it on the charger. The discharger was set at 0.9v cut off. Being a 6 cell pack x 0.9v per cell, the voltage should be somewhere around 6v total for the pack, right? Well the pack was reading 7.3v after the discharger...? Is this normal? BTW this is a GP 3300 nimh pack...?

...On any discharging device....The voltage cut-off is just for a split second.......after you trey a pack ,even if you bring the cells all the way down to zero volts...the second you disconnect them from the trey....the cells will re-bound to around 1.2 to 1.23 volts per cell......this explains your 7.3 volts (total pack voltage)..............The idea is to bring them down with the trey so that when they rebound they will as even as possible before your charge..........Hope this helps some............

Yes, it's quite normal, the .9V per cell reading is only when there's a specific load placed on the cells. When there's no load, the cell's voltage will return to normal, but as soon as any load is placed on them again, it'll go back down FAST....
