Nikon Multi-Power Battery Pack MB-D18
The MB-D18 is a water and dust-resistant multi-power battery pack. It increases the frame rate and extends the autonomous operating time of the D850 DSLR.
Used with the D5’s rechargeable Li-ion EN-EL18B battery inserted, the MB-D18 will increase the D850’s maximum frame rate to 9 fps. A single charge of this battery pack lets you shoot up to 5140 ¹ shots and record up to approx. 210 minutes of video.
Use of the MB-D18 also enables a steadier grip on the camera when shooting in portrait mode. Alternative shutter-release, multi-selector and AF start buttons ease operation when holding the camera in the vertical shooting position. And the pack features secondary main- and sub-command dials.
¹ In single-frame release mode, based on CIPA standards.
