nimh batteries died?

i have two elite 4500 mah 6 cell packs for my brushless boat. the packs sat all winter and when i went to charge them they both seemed to be at 0.00 volts ive been cycling them individually on my 989 but they don't seem to be discharging fully as the discharge mah is less than the charge mah...i cycled one of the packs 3 times at .5 amp charge/1.0 amp discharge (took forever) after that was done i discharged at 10 amps and it didn't discharge as much as it had just charged. (put in about 3400 mah, took out about 2400) now im trying charging at 4.5 amps (1C) to see what itl put into the battery. oh and i have the peak mv pumped up to 11 (temp sensor is set to 130 to prevent overcharging)

does anyone have any thoughts as to the lack of fully discharging, or any other ideas to help these batteries

i know i should get lipo but i just bought one for my savage and have no money

thanks
