    I have some 9.6v nicad batteries for a cordless drill.
    What is the best way to completely discharge these before
    recharging?(I use a 12v tail light bulb for some 12v nicads but don't
    think that would work in this case.)
    I've seen a home brew box used to rapidly discharge badly formed
    nicads thereby restoring them to some usable state.
    Anyone know what it'd take to build one of these, or where I might
    purchase one?
    Thanks in advance for any assist.

    2. Be very careful not to deep-discharge the battery, this can do
    Sorry, I forgot to say the most important thing: to avoid deep-discharge,
    discharge the battery to 80 pecent of it's stated voltage, i.e. for a 1.2V
    battery, you would discharge to 1V but no more. I guess for 9.6 you
    should stop the discharge at about 7.7V.
