Nikon EN-EL18d Rechargeable Lithium-ion Battery

  EN-EL18d batteries can charge the battery within the Z 9 mirrorless camera or power the camera. To do so, connect the camera to a computer using a Nikon UC-E25 USB cable (sold separately). The UC-E24 USB cable that comes with the camera cannot be used for this purpose. The EN-EL18d batteries cannot be charged using the older MH-26, MH-26a or MH-26ak battery chargers.
