The Pixel Vertax Battery Grip for Nikon D80/D90 Camera is an optional battery grip with improved ergonomics designed specifically for the Nikon D80/D90 . It allows users to load a choice of one EN-EL3 battery packs. With two packs, the already-impressive battery life is doubled, compared to using a single EN-EL3 pack in-camera. This is especially useful when taking advantage of the camera's movie mode or Live View mode - operating modes that use more power. In addition, with the included battery magazine, you can also run the camera off six AA/LR6 batteries.
