I have also seen it happen...running wet cell NiCad's for a back up source
of power for cesium beam frequency standards. These units we periodically
discharged and recharged as a preventative maintenance procedure, and they
did develop memory. The fix was to vary the preventative maintenance
discharge time/amount. H/P factory support helped us solve this problem.

This is (almost) a myth. The Ni-Cad memory phenomenon
does exist, but I can almost promise that no-one
reading this has ever experienced it. It requires
that the partial discharge/charge cycle be repeated
*****EXACTLY***** many, many times. It was discovered
in a satellite (and eventually duplicated) where the
battery discharged for a precise length of time into
a precise load, and then was recharged for a precise


I Beg to differ with you.
I have on occasions, and know friends who have damaged
Ni-Cad batteries. They were damaged by partial depletion
then recharging. They were in sealed waterproof torches
and over a period of time the batteries were damaged by
that method of charging. I now always run my batteries from
full to empty no mater what type.
