Lithium batteries are available in many different versions, which differ in terms of cathode, electrolyte, and separator. They are available in different designs and sizes to accommodate a wide range of applications. Because of their high voltage of 3 volts, high capacity, wide temperature range, and long shelf life (due to low self-discharge) they have a wide range of applications.
Main application areas are car keys, watches, medical equipment, toys, LED flashlights, and of course any form of memory back-up.
They come in a variety of different sizes. The cells are used either in a battery holder or pins which are welded to the cell.
