If you are deleting in the field, you are also using the LCD, which
is the major battery hog.
Use the screen less, use it to check histograms avery now and again
(especially if your light has changed).
I can fill a one gig card shooting jpeg on a set of four 2200 MA NiMh
batteries. Thats something like 600 shots on average.
