Re: [CAD_CAM_EDM_DRO] Digital camera battery pack

Though a single AA cell is "nominally" only 1.5 VDC (not talking about NiCad
here!), the total "fresh" voltage of four in series is closer, actually, to
6.7 VDC! It is perfectly safe to "feed" 6.8 VDC into a digital camera which
uses 4 AA cells for power. MY Nikon's connector says "6.5 VDC". NiCad's are
almost never over 1.3 VDC, even when freshly-charged. The newer NiHydride
are MUCH better; no "memory"; higher current out (lower internal Z), much
larger "amp-hour" capacity. Accordingly, more $$££ each!
