Hello again,


I made a quick Internet check.  See:
ng  for some comments.  No mention of whiskers however.  Here is a quote.


"To zap a NiCd battery, a 47,000mF capacitor is charged to 90V, after which
the raw power is discharged directly across a single NiCd cell of 1.2V.
After the shock treatment, the cell is cycled and then zapped once more.
Experts say that once a cell is treated and used in service, zapping will no
longer improve performance, nor does it regenerate a weak cell."
