Types of Battery

Batteries are used to supply power to appliances and there are generally two types of battery, one is primary and another is secondary. The primary battery are made for only single use. Once it is used, it cannot be recharged and is thrown away. For example:- disposable batteries.

Secondary batteries are the ones which can be recharged if it is over or it can be recharged and used simultaneously. These are charged by using electric current. For example: batteries used in phones, laptops etc.

Secondary batteries are further classified into:

  • Lead Acid Battery
  • Lithium Battery
  • Nickel Cadmium Battery
  • Sealed Maintenance Free Battery

Lead Acid Battery

These kinds of batteries require proper care and maintenance for lasting longer. These are used in inverters, automobiles and in backup power systems. It has to be charged for a longer duration and performs good when maintained properly at regular intervals. These provide the best value for power and energy per kilowatt-hour.

Lithium Battery

This battery is used in portable devices and such as phones, music players etc and has capacities depending upon the size of the battery. These are of high density and has a potential for higher capacities. Therefore, it can also be used to provide high current in power tool appliances.

Nickel Cadmium Battery

This battery can be recharged many times and has a more physical and electrical withstanding capacity. It has nickel oxide as the cathode and cadmium as the anode with potassium hydroxide as the electrolyte. These batteries are used in portable computers, cam recorders other small battery operated instruments.

Sealed Maintenance Free Battery

These battery requires minimum maintenance and can be used in supplying consistent and low power such as UPS applications. These are used to deliver instant power are used in power deficit areas such as rural areas. These are used with appliances when you need store important information when the power goes out.
