Nikon’s MB-D12 is a Multi Power Battery Pack for the Nikon D800/D810 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.
