    I shoot news and sports for a local newspaper which uses Nikon products exclusively. We have been using the battery pack with 8 AA batteries for over a year. These always ran out before the game was over.(football, basketball, soccer,etc.) In the two weeks the BL-3 has been in use with the EN-EL4 battery, we have saved at least 32-AA alkaline batteries. That's big money savings. There is no down side to that!

    The MB-D10 grip works best with the BL-3 chamber cover and EN-EL4a battery:
    - longest battery life
    - only one battery to charge (instead of 8)
    - percent remaining charge report in camera
    - shoot at 8 FPS

    If you opt for the 8 AA battery choice then:
    - cheaper as do not have to buy BL-3, EN-EL4a battery and charger
    - still shoot at 8 FPS
    - 8 batteries to charge instead of 1
    - do not last as long
    - no percent remaining charge reporting

    If you opt to use more EN-EL3e batteries in the grip then:
    - you can only shoot at 5 FPS

      Even though the price seems to be a bit more to what it should be the product in itself is made great quality wise and works perfectly. Certainly helpfull for persons who already have EN-EL4 and EN-EL4a battery and the charger to add lot more shooting time.

        this increases the battery strength of my grip, by allowing me to use the better en el4 battery and increases continuous shoot speed to 8 frames per second and great shoot bursts before stopping to write to the CF card

        Comments about Nikon BL-3 Battery Chamber Cover for MB-D10, MB-40 Battery Packs:

        One cannot use the rechargeable lithium battery without adding the chamber cover to the Nikon battery pack for cameras designed for it. It seems like Nikon prefers to nickel and dime by selling pieces of necessary items. I understand that using different, less expensive batteries don't require the end cap, but it does seem like an item that might just be sold with the battery pack. Perhaps it is considered too high end an item that would cause the pack to be too expensive for most. I was merely surprised I had to make yet another purchase to get outfitted. However, that said, once purchased, the entire battery pack configuration is absolutely worth the price.

                                when you pay more than $100 for a battery it should just come with one of these and it is necessary if you're shooting with the d700.

                                  I own a D3 and a D300s, 3 for photos and the 300s for video. We all know shooting video kills batteries. I love the fact that I don't need to purchase more D300s batteries for my video projects after buying this adapter and a vertical grip. All of my D3 batteries are now compatible with my 300s! The EN-EL4's last longer too, so I don't have to change them near as much as the EN-EL3's.

                                  A must have if you already own EN-EL4's and want to use them with your vertical grip!

                                  It is a little$pricey though if you don't own a D3 & want to purchase the EN-EL4's (&70ish) and a charger ($100ish) separately..

                                  This little accessory lets you use EN-EL4 batteries in your MB-40 (for F6) and / or MB-D10 (D300(s), D700) battery grips and is necessary if you want make use of the higher frame rate feature. Further more those batteries deliver higher capacity which gives you a lot more shots per charging cycle. Unfortunately that item isn't always on stock. It should be part of a battery grip kit.

                                    How can you review a cover? I paid enough for the MB-D10 grip, the EN-EL4a battery, and the charger. This should have come with the grip. I love Nikon equipment, but they sure do nickle and dime you to death.
