steve has a lot of others things to say about this camera
but since you specifically mentioned the batteries...
"""
The L18 is powered by two standard AA type cells. Using two 2650mAh NiMH rechargeable batteries I was able to capture just under 100 images, several movies and completed all of our tests on a single charge with power to spare. Nikon claims that using NiMH batteries, the camera can capture up to 300 images, or 650 images using Lithium batteries. Another good thing is that if your batteries run low, you can pick up two new AA batteries almost anywhere. We always recommend using NiMH batteries when possible, they last longer, and will save you money in the long run; just be sure you have an extra set charged and ready. """"
