How does a battery work?

Indeed, sir. A battery works by converting stored chemical energy into electrical energy through a process known as electrolysis. Inside the battery, there are two electrodes, one positive and one negative, separated by an electrolyte, which allows ions to move between them. When the battery is connected in a circuit, a chemical reaction occurs at each electrode, causing electrons to flow from the negative electrode to the positive one through the external circuit. This movement of electrons creates an electric current, powering whatever device is connected to the battery. A well-maintained battery can provide reliable power for many hours, or even years, depending on its type and usage.
