EN-EL3e Li-ion Rechargeable Battery for Nikon digital SLR cameras. Keeping a spare battery on hand ensures that you will always be ready to capture the images you want most. And, while Li-ion rechargeable batteries are less prone to recharge "memory," using the normal complete charge of one battery before recharging will better ensure optimum rechargeable battery life. A freshly charged spare battery allows this and provides uninterrupted photography.
