In the video, a person is holding a small red toy helicopter in their hand. The helicopter has a clear plastic body and a black tail. The person is using a small screwdriver to remove the screws from the bottom of the helicopter. Once the screws are removed, the person opens the bottom of the helicopter to reveal the internal components. The person then proceeds to remove the battery from the helicopter. The battery is a small, rectangular, black component. The person then replaces the battery with a new one and screws the bottom of the helicopter back on. The video ends with the person holding the helicopter in their hand, showing the new battery installed.
