Product Description:
The compact Lithium-Ion EN-EL3a is identical to the EN-EL3 but has more power. The EN-EL3 has 1400mAh and the EN-EL3a has 1500mAh and thus enables your Nikon digital SLR to shoot even more images than on an EN-EL3.

Rating : - Great buy
Great price on a very reliable product. And don't discount the importance of having 2 batteries. There is nothing worse than having a great shot and a dead battery.
