The durable, lightweight GoPro Battery Door is a replacement for the original side battery door that covers your GoPro HERO13, HERO12, HERO11, HERO10, or HERO9 camera's USB-C port, SD card slot, and battery and protects them from dirt and debris. It also maintains the camera's 33' native waterproof rating. It is the same door model that comes with the camera and easily snaps into place without any tools required.
