Nikon's MB-D11 Multi Power Battery Pack is a grip that attaches to the Nikon D7000 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 6 AA batteries. A holding case, contact cap and user's manual are also included. This item is sold as seen for spares or repair. Please read the description in full before purchasing.
