Related Questions and Answers

Q: 1. Someone suggested to me that there is a way to charge the batteries while in the grip, thereby avoiding the necessity of purchasing the expensive charger. Is that true? If so, does the charging cord come with the grip, or must we buy that separately?

A: Battery must be removed from the grip and recharged with a separate battery charger. There is no provision for charging the battery while its in the grip. If using a EN-EL18, you will need to buy a charger for it.

Q: 2. will my dual battery charger and batteries from my D3X work for the D850?

A: Hi, batteries and charger for the D3x are not compatible with the D850.

Q: 3. How much height does this add to the camera? I am trying to decide which case to buy and want one that can fit the grip on the camera body and store vertically in the case.

A: added height of 1.75 inches is correct

Q: 4. Does this require a cable or cord to be plugged into the camera like some of the Vello models?

A: No wires needed, remove dust cover(covers electrical connection for extra battery pack) from bottom of camera, plug battery pack into camera's electrical connection and tighten threaded screw with thumb turn on battery pack into the camera's tripod mount. Install battery, that's it. If you have a battery in the body and the extra battery pack, I don't know that it does anything except add more weight to an already heavy camera. I use the extra battery pack for vertical shooting and love it. Don't worry about loosing the tripod mount as there is another on the battery pack.

Q: 5. can you switch batteries without powering off camera?

A: Yes, as long as you have a battery in the actual camera. I shoot races and do this all the time without missing a shot.

Q: 6. Does the EN-EL15 battery have to be inside the D800 for the grip to work? This assumes the 8xAA tray or the other EN-EL15 or EN-EL18 being in the grip.

A: One EN-EL15 battery is required in the camera itself in order to work. From there you have the option of adding a second EN-EL15 to the grip or use the AA battery tray.

Q: 7. Can I use rechargeable AA batteries in the included tray that comes with this product?

A: Yes, they work fine in mine. The battery info only displays the charge level graphically, not as a percentage, and neither the number of shots nor the battery age are displayed. Using 8 (required AAs) adds quite a bit of weight to the camera and I believe you are better off just carrying around a couple of spare EN EL-15s to use instead, but each to his own. Bottom line: they work fine.

Q: 8. Is the MB-D18 manufactured in Japan or China?

A: Following unit is made China.

Q: 9. Is the MB-D18's buttons illuminated, like the D850 it attaches to?

A: No, the battery pack on the Nikon MB-D18 Multi-Power Battery Pack BH #NIMBD18 is not illuminated like the Nikon D850.

Q: 10. Is there any kind of indicator showing levels of the battery / batteries in the grip?

A: Yes, the camera shows battery levels in grip and or camera body.
