The EN-EL23 Rechargeable Lithium-Ion Battery from Nikon is especially for use with the Nikon P600 digital point and shoot camera. It can be used as a replacement part for the camera's damaged or non-functional battery. You can also carry it as a spare battery when going on long journeys, where there are very few chances of recharging the camera. This enables you to keep recording photos for a longer period. This battery has a capacity of 1850 mAh and a power output of 7.1 Wh. You can use Nikon's MH-67P battery charger to recharge this battery when it is not lodged inside the camera.
