Excellent battery replacement for the original EN-EL3E that came with the new DX-format digital SLR flagship - Nikon D300S. It holds more energy than the original Nikon battery, and it lasts a lot longer than the original, and it just does what it's supposed to do...power the camera!
Keeping a spare battery on hand ensures that you will always be ready to capture the images you want most. And, while Lithium-ion rechargeable batteries are less prone to recharge "memory," using the normal complete charge of Nikon D300s battery before recharging will better ensure optimum rechargeable battery life. A freshly charged spare battery allows this and provides uninterrupted photography.
