Nikon MB-D12

Nikon\'s MB-D12 Multi Power Battery Pack for D800 Camera is a grip that attaches to the Nikon D800 camera.
It provides extended battery power with the batteries (not included) in the grip, plus giving you a better, more secure and stable hold on the camera, making it easier to handhold at lower shutter speeds.
The battery pack is supplied with two battery trays--one that holds an EN-EL15 rechargeable battery, and one that holds 8 AA batteries. A holding case, contact cap and user\'s manual are also included.
This power pack accepts 1.5V LR-6 (Alkaline), Lithium (FR6), Ni-MH (HR6) or Ni-Mn (ZR6) batteries.
