Always test cells and/or batteries with a suitable load which will vary with
type and size of cell. Under no load conditions your voltmeter is likely to
register the basic chemical emf of the cell, and the effects of internal
resistance will not be registered. From memory, I think about 1 volt per cell is
about right for a NiCd or NiMH cell - measured under load, of course. This
rises to over 1.2v when charged, and even higher when being charged.
