Nikon EN-EL4, EN-EL4a Battery by Wasabi PowerSKU: WSB-BTR-ENEL4
Compatible with the following Nikon models:
These do everything I need them to do-reliable and the right price too. I use these in my Nikon D2X and D3 cameras. One battery lasts all day.
Battery seem to hold charge.. wasabi went the extra mile to resolve an issue I had with mismatched battery caps..
i have found both the EN-EL4 as well as the EN-EL3 batteries I use for my camera are a good replacement over the costly Nikon branded batteries I have been using. So far so good.
I ordered a battery and a battery chamber cover for my Nikon D3. Even though the box listed the D3 as compatible, the chamber cover was clearly designed improperly. Given the cost of the cover and the cost to return it, I just recycled it. But I'm still unhappy.
This was my second order from Wasabi, and the first was OK.
Ordered my second battery and worked perfectly and fast shipping. This is my store for replacement batteries.
