I know that Japan has limited the amount of energy that can be in a lithium battery making the D800 battery not among the absolute best options. With the optional battery pack, I believe different type batteries can be used. What do you guys think is the best battery that can be used with the D800? I don't have any experience with the batteries beyond the EN-EL3e that I use in my D200.
