I've managed to get some life into dead nicads before now by blasting a few
amps through them (5A or so) for a few seconds to get them working, then
cycle them up and down half a dozen times on a fast charge/discharge cycle.
It works about 50% of the time - the ones that work get about 50-80%
capacity, the ones that don't get about 2% capacity and end up in the trash
(err.. I mean 'they are recycled'.)
