Works Just Fine

Works great. Just make sure you click that little lock on it.

Make your D850 work

The D850 is great, but if you use a D5 battery it will be even better. I have both (D850 and D5). While the D5 is still faster, this really wakes the D850 up when you need the extra power. A little bit of a shame it is not included with the MB-D18, but it's fairly inexpensive compared to the camera, grip and battery.

question

I just want to make sure I have this straight. If you have the MB-D12, you can purchase this chamber cover and an EN-EL18a battery to expand the power capacity (going from an EN-EL15 to this 18) of my D810?

question

can i use the new ENEL-18a battery with this? Does anyone know how many shots one can take with ENEL-18s vs. ENEL-15?THanks
Asked by: Anonymous
The New EN-EL18a battery is compatible with the MB-D12 battery grip with the BL-5 battery chamber cover, yes. Nikon doesnt list battery life with the new EN-EL18a, but with the older EN-EL18 they estimate 1,400 shots by CIPA standards. With the EN-EL15 they estimate 900 shots by CIPA standards.

question

Will this fit the Vello BG-N19-2 Battery Grip for Nikon D850 or only the Nikon battery grip?
Asked by: Quinton
Don't know the answer. I have the Nikon grip. I will say that the grip with the powerful battery works well. and 9 frames per second is quite an advance over slower cameras.

question

Asked by: andres
No, it works with the EN-EL18/18a battery only.

question

If I buy the MB-D12, do I also need to buy the BL-5 Battery Chamber cover as well or will the MB-D12 battery pack, as ordered, hold on N-15 Battery?
Asked by: Anonymous
The BL-5 cover is used with the en-el18 battery. You can use the en-el15 battery with the MB-D12 grip as ordered.

question

How can I charge the batteries of the EN-EL18a if the charger is not in stock. Do the camera D810 charger supply power (full charge overnight) to the MB-D12 to power the EN-EL18a ?

question

can this cover fits mcoplus grips and fit en-el18 battery to get 9fps with extra longer battery life?
Asked by: Ang W.
I bought the Nikon battery grip for this and it does fit en-el18 Batteries. You may theoretically get 9fps with en-el15a also inserted but it will depend on your XQD Memory card and how fast it is. Also, there is no reason to believe that it won't fit the mcoplus grip if the mcoplus grip was meant to have an en-el18 battery.
