Ni-Cd restoration [RE-wrenches]

[William Miller]

Allan:

In a previous life I worked as a two way radio technician.  We zapped nicad
pager batteries by giving them a momentary jolt at 12 volts, normal
polarization (supply plus to battery plus).  We gave 1.2 volt batteries a
zap with a 12 volt supply.  This would translate to 180 volts DC for your
tool batteries!  Instead, I'd try 24 volts and if that was not successful,
48 volts.  We held the contact for about 2 seconds.  It brought many
batteries back to life.

Good luck,

William Miller

PS:  Nice term: dendrites!
