Ni-CAD battery questions

[jrz126]

My cordless drill batteries finally crapped out on me. The battery charger says they are defective. I measured them with a voltmeter and it read 0.000 V. I measured the resistance and I think it was somewhere around 1-5 ohms, I cant remember exactly.
I've been reading up on possibly fixing them by giving them a big slug of current, but will that work on a battery that is reading 0V?

I have zapped shorted old Ni-Cads but the shorting problem soon returned.
They are old, very toxic and obsolete. Replace them with new Ni-MH cells and hand the Ni-Cads to a hazardous waste disposal facility.
