I own this camera and before I picked up my rechargables at Newegg it ate through the plain old Energizers. Now I can take 60-70+ (flash pictures with the LCD screen on) per set before recharging. Depending on your needs, you can judge whether that is enough battery life for you. I have 2 sets, rarely will I ever take over 100 pictures in a day, it's plenty for me.
As a casual user and not a pro by any means, I'm VERY satisfied with my D-510 Zoom.
