Yes, but these were NiCad's with the memory problems.

BTW I have found a method of curing  the memory, shorts, and other problems 
with the NiCads. I fixed up a 'bench' that allowed me to reverse charge the 
batteries with voltage well over 20 volts, I would cycle the battery with 
normal/reverse for a few seconds each and after 'maybe' a half dozen tries 
the battery would act normal (the voltage would peak out at 5 - 10 volts - 
probably burned out the short with the high voltage pressure) and then would 
take a normal charge (and work for a long time normally.)

I see in your later posts that you found the better answer (not NiCads) to 
your problem.

I guess the *industrial* opened the idea door.
