Yes, Roughly 12 times longer than he gets out of his internal battery.
But that answer doesn't give much of an argument for me being the
battery man on his trip.
The 722 being such a variable use recorder does not list wattage as
it would get to complex. Once a field menu setup has been choosen it
would be much easier to just watch a amp meter on the external
battery to calculate the actual draw. The manual does give a few
guidelines on watts but not a full averaged range. There are probably
enough of these machines on this list that it would be nice to know
the full impact of the display lights, 24 bit vs 16 bit, etc for this
machine. If the current draw is highly variable from the hard drive
write cycles and the like then it would need to be tested for a
averaged or "padded" draw. This would involve testing with a very
large capacitor such as a car "boom car" 2f capacitor between the
recorder and the battery. Then testing the current draw between the
capacitor and the battery.
