BATTERY: A battery in automobiles, is an electrochemical device which produce electricity (current) through chemical action inside it. The battery does not store electricity a electrons. The battery stores energy in the chemical form. The electrical energy is produced in the battery by the chemical reaction that occurs between two dissimilar plates that are immersed in a electrolyte solution. The automotive batteries are rechargeable, therefore, they can also convert a electrical current into chemical energy and stores that energy until it is needed. The amount of electrical energy that a battery can produce depends upon the size, weight, active area of plates, and the amount of sulphuric acid in the electrolyte. The greatest requirement of electrical energy from the battery occurs when it supplies current for operating the starter in When the engine is started, the vehicle's charging system (generator) supplies current to recharge the battery and to run the electrica...
