how to determine possible bad cell?

have a 5 cells receiver pack buried in plane..thought it was new.
it is NIMH..say 1600 mah capacity.
what should I set my charger at to test it?
1.1 volts/cell cutoff? 1.4 volts/cell max... ?
charge at .1C discharge at .3C or so
how much of capacity should it have before it gets tossed
what will peak pack voltage be for a 5 cell 7 volts ?

thanks..sorry ..been out of the game for a while.

nims can pretty much be drained to 0 without hurting them

Individually, perhaps. In series, definitely not as this may cause reversal and permanent damage to lower capacity cells within the series pack.
