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. When using an EN-EL18B battery to power the MB-D18, use the optional BL-5 battery chamber cover (sold separately).

¹ In single-frame release mode, based on CIPA standards.
