FYI: ni-cads self discharge so fast that you can almost watch the curve
on an O-scope! I use a strobe from a throw-away camera to blast the
whiskers off my reluctant ni-cads. I've done this for years and it works
most of the time.
Try it! DavidQ.

Yeech. After rebuilding that battery with exact cells, worked in
fast
charge just once, after that I can't get fast
charge from it, now
While perhaps a bit off topic, there are ICs available that can
recover
bad Nicad batteries. Basically they pulse the battery with high
current
for a brief time (milliseconds), wait, monitor the voltage, and
repeat.
I've been thinking about building one since it seems like it would be
a
very good addition to the bench.
