The Nikon EN-EL15C Rechargeable Li-ion Battery is specifically designed for use with the Nikon Z8 camera. With a capacity of 2280 mAh, this battery provides long-lasting power for extended shooting sessions. Battery is used but has been in rotation with other batteries so is in great shape. Minor marks on battery as to be expected from inserting/removing from camera. Has three small pen marks on it which were used to identify battery. Please ensure this is the correct battery for your camera as I don’t accept returns.
