Nikon BL-4, Replacement Battery Chamber Cover for the D-3 Digital SLR Camera

This one of those little parts that for a Nikon camera that no one else makes but Nikon and are hard to find second hand. Good thing these battery covers are fairly indestructible, and still available as new stock for those of us still using D3 cameras.

OEM to the rescue

works great.  just charge with the door attached to the battery then put it in the camera.

They are made to be very durable

I bought this along with a new battery to replace an aging battery in an old D3 that I recently picked up for shooting action events.

Fit battery and camera perfectly as should be for OEM parts
Finish is also what you would expect.

a perfect replacement

Perfect fit

This is a genuine Nikon battery cover for the Nikon D3. It's an exact replacement for a broken battery cover or it can be installed on a spare battery so you're ready to go when swapping out a low battery for a charged one.

Genuine Nikon BL-4 battery cover

I use 5 EN-EL4a batteries for the D3s. Each battery and cover is numbered with a label to keep them identified. The BL-4 covers that I bought from Adorama are terrific, fit perfectly. Now I don't have to switch covers to different batteries. Adorama had, by far, the lowest price, and free shipping. 
Thank you Adoroma.

Can't loose with Nikon

BL-4

I attach it to my backup battery for my D3s, so when I travel, I wouldn't forget anything.  I do have it attached to the battery while it's being charged...  Works great...

perfect product, spare for the D3s...

This component is a replacement for a battery compartment latch/cover that was damaged when the camera fell from its mount. [...] functions perfectly!

I bought this to make swapping batteries in and out of my D3 a simple and quick affair.  Its design is simple.  It is a bit bulky in my bag, but I can accept that for the speed of swapping batteries in the middle of a shoot.

Great Accessory

I  purchased it as a Back-Up for my D3.   It is really a MUST HAVE ... lose the original or drop it in the wrong place,  and you are out-of-business.
