Batteries

A battery is simply an electrochemical cell or group of cells that generate electric current. Batteries are the devices that generate current using redox reactions. These reactions proceed by the transfer of electrons. An ideal battery or cell should produce a constant voltage. A battery should actually be light in weight.
