A great analogy for batteries is a water pitcher. When the pitcher is being filled with water, it is charging. When the pitcher is pouring out the water, it is discharging. In energy storage parlance, this process of a single charge (i.e., filling the pitcher) followed by a single discharge (i.e., emptying the pitcher) is called a "cycle."
