NiCd *cells* may be stored in any charge state, although there may be some
reason not to store them for extended periods in a deeply discharged state.

Storing NiCd batteries in a fully-discharged state can also be a Bad Idea,
as self-discharge will eventually cause one or more of the cells to get
in a bad way; i.e., the cells do not all discharge at the same rate, and so
it's conceivable (esp. for higher-voltgae batteries) that one or more could
wind up seeing a reverse charge.  Still, this would take an extended
period of storage before any real problems are likely, assuming that the
battery wasn't nearly  full-discharged to begin with.
