The heart of the Nikon D3 (Ronald L. Day, 2008-11-17)

The EN-EL4a is the finest battery Nikon has produced to date. It is powerful, reliable, and it holds a charge noticeably longer than any of its predecessors. I view it as the heart of my Nikon D3 system. During critical shoots, I accurately monitor the condition of the EN-EL4a via the setup menu on the D3. It reveals the number of exposures made with it, the percent of charge remaining, whether it needs calibration, and its estimated lifespan. Using this procedure, the EN-EL4a has never let me down. A second EN-EL4a for backup is recommended, as a full charge takes a little over an hour.

Nikon EN-EL4a (Picture This, Arlington, TX, 2008-07-07)

This is the original Nikon EN-EL4a battery for the D300 with MB-D10 vertical grip. Works perfectfly. The charge lasts forever. Don't buy the generic replacement for this battery, they DON'T work. I've tried 3 different generic brand & none of them work. I ended up wasting more time & money. Just go with the Nikon & your safe.

Excellent (Edgar H. Tan, MD, Global, 2008-04-19)

I bought this as a spare for my D3 and to rev up the speed of my D300 used with the optional BL-3 cover on the D300 vertical battery grip..it's good to have it on standby! This battery could last a long long time but nobody would feel secure without having one on reserve!

Outstanding (James D. Holbrook, Houston, TX, 2008-04-06)

Simple and works as advertised.
I put a freshly charged one in my D3 and have taken at least 2000 pics with it and it's still showing full charge.
Outstanding.

Why save a few $$ buying an off brand that may or may not work (be VERY careful with Lithium batteries!!)
Just spend the extra few $$ and get the real thing.
