The jelly roll or Swiss roll design is the design used in the majority of cylindrical rechargeable batteries, including nickel–cadmium (Ni-Cd), nickel-metal hydride (Ni-MH), and lithium-ion (Li-ion). The design has this name because the cross section of the battery looks like a Swiss roll.
A Battery: Eveready 742: 1.5 V: Metal tabs H: 101.6 L: 63.5 W: 63.5 Used to provide power to the filament of a vacuum tube. B Battery: Eveready 762-S: 45 V: Threaded posts H: 146 L: 104.8 W: 63.5 Used to supply plate voltage in vintage vacuum tube equipment. Origin of the term B+ for plate voltage power supplies.
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] The battery comes in many nominal voltages depending on the specific chemistry used.
Cylindrical cells: KR or HR followed by a letter indicating discharge rate (L, M, H or X for low, medium, high and very high, respectively); then another letter may be added to indicate use at elevated temperatures (T or U) or rapid charge (R); then maximum diameter in mm / maximum height in mm. E.g. KRL 33/62, HRHR 23/43

HiNa also revealed three sodium-ion products, the NaCR32140-ME12 cylindrical cell, the NaCP50160118-ME80 square cell and the NaCP73174207-ME240 square cell, with gravimetric energy densities of 140 Wh/kg, 145 Wh/kg and 155 Wh/kg respectively. [93] The cycle life of Hina's Battery was reported to by 4,500 cycles in 2022.
An A23 battery is cylindrical and approximately two-thirds the length of an AAA battery, measuring 28.2 mm (1.11 in) long and 10.0 mm (0.39 in) in diameter, with a typical weight of 8 grams. An A23 battery is an 8- cell device with a nominal voltage of 12 V.
A rechargeable battery, storage battery, or secondary cell (formally a type of energy accumulator), is a type of electrical battery which can be charged, discharged into a load, and recharged many times, as opposed to a disposable or primary battery, which is supplied fully charged and discarded after use.
