What I used to do with Nicads when I raced radio controlled cars was to shock old batteries to life with a high amperage pulse. Also reflex pulsing ( +ve then -ve) pulses sometimes helped revive old tatered batteries. Now, I don't think you should follow this advise because any external charging like this might fry the internal circuitry of the battery. But if it were easy to rip the cells out of the batteries you might try finding a high tech hobbyist nicad charger. Also, if it were easy to rip the cells out, you could buy new ones in bulk and re-build the bateries your self. Of you might be able to say contract out the rebuilding of a number of batteries to a place like BTI batteries. Like you say though, they have been sitting empty and may have just self destructed. They are probably nearly useless =( sorry. dc >I have recently bought a lot of Duos in VERY good condition with the >exception of their batteries.
