What is Rechargeable battery?
A '''rechargeable battery''', also called a '''storage battery''' or a '''secondary cell''', is a [[battery]] that can be recharged over and over again with [[electricity]].<ref>{{Cite web|title=Other Rechargeable Batteries {{!}} Introduction to Chemistry|url=https://courses.lumenlearning.com/introchem/chapter/other-rechargeable-batteries/|access-date=2021-06-17|website=courses.lumenlearning.com}}</ref> A battery that is not rechargeable is called a [[primary cell]] or disposable battery.<ref>David Linden, Thomas B. Reddy (ed). 2002 ''Handbook of Batteries'', 3rd edition. McGraw-Hill, New York. ISBN 0-07-135978-8</ref> It is thrown away after it no longer works. The voltage of rechargeable batteries can be restored by passing an electric current through the battery. Car batteries, for example, work this way..<ref>{{Cite web|title=Rechargeable Batteries|url=https://www.energizer.com/batteries/energizer-rechargeable-batteries|access-date=2021-06-17|website=www.energizer.com}}</ref><ref>{{Cite web|last=Foundation|first=In association with Nuffield|title=Rechargeable cells: the lead–acid accumulator|url=https://edu.rsc.org/experiments/rechargeable-cells-the-lead-acid-accumulator/391.article|access-date=2021-06-17|website=RSC Education|language=en}}</ref> Rechargeable batteries are not always chosen. Each battery costs more to make, and has more dangerous [[chemicals]] than disposable batteries. Rechargeable batteries can be used for many smaller electronics such as [[MP3 player]]s and [[flashlight]]s. Almost all [[mobile phone]]s and [[laptop computer]]s use them. They are also used for [[Car battery|car batteries]]. == Types of rechargeable batteries == * [[Lead-acid battery]] * [[Nickel-cadmium battery]] * [[Lithium-ion battery]] * [[Nickel-iron battery]] * [[Nickel metal-hydride battery]] * [[Nickel–zinc battery]] == Related pages == *[[Battery]] *[[Dry cell]] *[[Table of batteries]] == References == {{reflist}} [[Category:Batteries]]
