Lithium-ion batteries (rechargeable)[edit]

An alkaline AA size battery and an 18650 size lithium ion battery

Cylindrical lithium-ion rechargeable battery[edit]

Lithium-ion rechargeable batteries are generally not interchangeable with primary types using a different chemistry. Many are also available with internal protection circuits that can increase their physical length; for example, an 18650 is around 65 mm (2.56 in) long, but may be around 68 mm (2.68 in) long with an internal protection circuit. Some such circuits increase cell diameter instead. The increased dimensions may mean the cell will no longer fit in battery compartments intended for cells without such circuitry.

Commonly-used designation numbers indicate the physical dimensions of the cylindrical cell, as given in IEC standard 60086-1 for cylindrical primary cells. The first two digits are the nominal diameter of the cell in millimetres, and the three following digits are the height in millimeters. Manufacturers may use non-IEC designations for their products.

3812038120s, 38120HP8,000-10,00038120LiFePO4 3.2V. LiFePO4 properties: long lasting (2000+ cycles), safer, more stable, good continuous/peak discharge rates (3C/10C), less energy dense. These cylindrical cells are widely used in EVs including electric bikes, electric scooters, electric cars / hybrid electric cars, UPS batteries, storage batteries for solar power systems, starter batteries for cars and motorbikes etc. The Headway 38120HP cells are used in high discharge environments as they have very good continuous/peak discharge rates (10C/25C). Because four cells in series produces a voltage range similar to 6 cells of Lead-acids and their fire-resistant properties, they can be used to replace a 12V lead acid car battery.[citation needed]
