An 18650 battery[1] or 1865 cell[2] is a cylindrical lithium-ion battery common in electronic devices. The batteries measure 18 mm (0.71 in) in diameter by 65 mm (2.56 in) in length, giving them the name 18650.[3]
Panasonic first developed the 18650 battery in 1994 "when there was a growing need for ever smaller and lighter storage batteries that could be used for ever longer periods of time".[4] They are now commonly used in power tools, electric bicycles, laptops, and electric vehicles.[5]
Chemistry
![[icon]](http://178.128.105.246/cars-https-en.wikipedia.org/wiki/File:Wiki_letter_w_cropped.svg){kind=small} | This section needs expansion. You can help by adding to it.

18650 batteries are most commonly lithium-based, although sodium-ion variants are available for purchase.[6] Lithium-ion batteries consist of an anode, typically made of graphite and a cathode, often of lithium-metal oxide.
Packs
18650 batteries are more commonly used in packs, where a BMS (Battery Management System) is required, especially once cells age and perform differently. BMS boards balance the voltage of cells in series and protect against over- and under-discharge.
