Because a significant percentage of alkaline battery energy is

Actually, it is current related. The larger the current draw, the lower the
voltage maintained by the cell; alkalines do the poorest, followed by NiMH,
NiCd and finally Li (1.5V). I am not really sure where LiIon would fall in
that ranking, but I suspect between NiMH and NiCd. That is why devices that
draw high currents will indicate that a set of alkaline batteries are dead
when there is in fact significant capacity left; they draw a high current and
drop the voltage of the battery down below 1.0V.

Well, just remember that when you finally install them, it's
probably wise to recharge them yearly when you change your smoke
alarm batteries, whether the Eneloops need charging or not. <g>
Actually, while the Eneloops will probably give you slightly fewer
shots per charge than you'll get from the lithium batteries, they
might produce slightly faster flash recycle times. You might want
to test this with a shot or two while the C743 is still using the
lithium batteries and then compare after the Eneloops are installed.


Keep some standard high capacity 2700mAh NiMH batteries around for those times
when they would be consumed in a day or so of picture taking and keep the
Eneloop or Hybrid batteries in the camera for the rest of the time.
