Don't forget that rechargeable batteries often perform at their best after several full charges and discharges. Their first full charge should be over several undisturbed hours (I'd suggest 8 or more hours constant, undisturbed charge before first use, on every set)
The best time to charge (rechargeable) lithium and and NiMH is somewhere between 80% and 20% of their full charge. Not sure if your cam has a 'fuel' guage that tells you at a glance of what status your cells are at (my D200 does to within a % point), but avoid charging too often below or above those levels (if possible)
I'm not sure in what environment you're shooting in, but here's some simple tricks to lessen battery discharge rate.
- mimimise the amount of reviewing on the lcd screen, perhaps even go into the menu to reduce the amount of time the screen stays on
- avoid continued long shutter speed images e.g. say 5 second duration expoures, as they draw power to 'hold' the shutter open.
- minimise flash useage, and perhaps adjust output of flash power if available.
- make sure your batteries are 'warm' i.e. body temperature as most cells discharge quickly, or last very little time in very cold temps.
- Also constant use of zoom and focus is a pretty big draw on power. I guess the best option is to attempt to have as much ambient light as possible, so that focussing does not 'hunt' around for lock on your chosen subject.
Unfortunately, even in the 21st century, some cameras chew through battery power very quickly...My D200 does this, my D70 was extremely efficient. I'm not sure what category your cam falls in, but just taking care of the batteries charge and useage, (and if they're removeable, get several sets), you should be able to improve their useability and life.
I'd suggest to get a set of standard alkaline or lithium batteries also just to see how long those last, as a guide.
Good luck and let us know how you go!
