In the video, a person is seen holding a black battery in their hand. The battery is rectangular in shape and has a small silver connector on one end. The person then inserts the battery into a black charger that is plugged into a wall outlet. The charger has a green light that turns on when the battery is inserted. The person then removes the battery from the charger and shows it to the camera. The battery has a label with some text on it, but it is not legible in the video. The person then inserts the battery back into the charger and plugs it into the wall outlet. The green light on the charger turns off when the battery is fully charged.
