What is the life (how many pictures can be taken) with the energizer e2 lithium batteries?

I have a 3.0 megapixel digital camera

Bukkake.

600 pictures

If you're going to take pictures regularly, you're much better off buying a set of NIMH batteries with a charger. They're about $25 and last a long time. 3-6 outings with e2's will cost the same as having batteries for a year.
