Battery is an electric device comprised electrochemical cell structure with external power supply terminals to other devices. Batteries are small scale sources of static electrical power. It is categorized as primary & secondary storage devices. A primary battery can be used until it gets discharged whereas; secondary power storages or batteries are of high charge holding capacity, chargeable for second time use.
Primary batteries such as voltaic cell, torch cell, pencil cells etc., are used for low voltage requirement which may nearly 12 volts. These primary storage sources of power mainly used in toys, light torch, communication circuits etc. Secondary or rechargeable batteries are dominantly used in automobiles and vehicles. Secondary storages of electrical power may supply approximately 450 amp of electrical current for use. In vehicles, lead acid batteries are commonly used in all types of automobiles to maintain functioning of lights, indicators, speakers, charging system etc. Lithium-ion power storage cells which are also secondary batteries used in wireless mobile phone devices.
Manufacturing companies of batteries provide wide range of power storage devices for several purposes. Today, any requirement of specific characterized power storage devices can be fulfilled with the help of online electrical & electronics stores at cheapest rates. Automobile rechargeable, domestic and industrial batteries are available on online websites by wholesaler electrical power supply devices at cheap rates.
