Car Battery

Car battery is a type of rechargeable batteries to store the function return electrical energy from the alternator. The entire electrical energy needs in a motor vehicle supplied by the altenator, though most of the batteries but the source of electrical energy from the alternator fixed. Electrical energy stored in the battery can be used for motor vehicle when the alternator was not working.

Motor vehicle starter batteries (usually lead-acid type) provide 12 volts of electricity by linking six galvanic cells in series. Each cell provides 2.1 volts so that a total of 12.6 volts. Lead acid batteries are made from lead discs and discs that separate lead oxide, which is immersed in an electrolyte solution 35% sulfuric acid and 65% water. This will cause a chemical reaction that releases electrons and flows through the conductor, so as to create electrical energy. When the battery is used, the surface of the lead reacts with sulfuric acid to form lead sulphate. And when the battery is charged, the chemical reaction is reversed; lead sulfate back into lead and lead oxide. When the dish back to the time available, the process can be repeated again.
