- According to the manuals of devices that use NiCad batteries, all of them
- that I have seen seem to say that you should charge it once in a
- while (every 6 months, depends).

- The way I figure is: if the battery "remembers" shallow discharge, one
- should not charge it until it is fully dischared. But I haven't heard of
- anything about "remembering" shallow charging. So I suppose you can
- charge it a bit, but make sure it is again fully discharged before you
- charge again!
