Battery is defined as:

Explanation:
A battery stores energy in chemical form and converts that chemical energy into electrical energy when it’s connected to a circuit. This conversion happens through electrochemical reactions inside the cell that push electrons from the negative to the positive terminal, producing current to power devices. The other statements describe a capacitor (which stores energy electromagnetically), a unit of current, and a safety device, none of which define what a battery does.
