I have a Ryobi battery-powered drill whose two batteries are -- for all intents and purposes -- dead. While poking around for replacements I came across this site:

http://resurrection.uniquedynamics.com/

Is that bogus or for real?

I also came across this:

http://www.hackaday.com/2005/08/26/how-to-...on-and-upgrade/

I suppose it can't hurt to try this one out (it's free and the batteries are essentially dead).

In short, can you "resurrect" a NiCad battery?

Thx,

Yes, We used to do it all the time at work. We used 7.2 vdc ni-cads. Apply about 14 volts. It would work 90% of the time. Put a amp meter in
series with the charger. At first it wont draw any current. As the thershold resistance of the battery is overcome it will start drawing current. Reduce the voltage as to not overheat the battery.
