EXPLANATION: Batteries are devices that CONVERT stored chemical energy into useful electrical energy. It CONSISTS of a number of voltaic cells connected in series by a conductive electrolyte containing anions and cations. A battery MAY be thought of as a clever variant of a standard exothermic chemical reactor that YIELDS chemical products with lower energy content than the chemical reactants._x005F_x000D__x005F_x000D_Also read about A device that converts mechanical energy into electric energy is called_______?
