How a battery works

A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit. The flow of electrons provides an electric current that can be used to do work.

BU-303: Confusion with Voltages

Charging and discharging agitates the battery; full voltage stabilization takes up to 24 hours. Temperature also plays a role; a cold temperature lowers the voltage and heat raises it. Manufacturers rate a battery by assigning a nominal voltage, and with a few exceptions, these voltages follow an agreed convention.
