When storing batteries for more than one year, charge *at least* once a
year to prevent leakage and deterioration of performance due to
self-discharging. When using a rapid voltage detection charger carry out
charge and discharge at least once ever 6 months.

" charge *at least* once a year" snip "deterioration of performance"
The above is if you plan on taking the batteries out of storage and
using them at that time. If your storage is truly long term and you
can take the time to charge and discharge a few times to bring the
battery back into service and back to their rated capacity then there
would be no reason to " charge *at least* once a year" You only get
so many cycles out of a Ni-Cad. Why waste them?

Do you expect somebody to store them for five thousand years?

Of course not. Let's be a little more realistic. Pick 20 years.


Would you rather fire up your vintage whatever with a battery
charged/discharged two or three times a year for the last 20
years or would you rather retrieve a 20 year old unused Ni-Cad
and bring it to life?

20-40 extra cycles is nothing.
