For example, a CR123 battery is always LiMnO 2 ('Lithium') chemistry, in addition to its unique size. The following tables give the common battery chemistry types for the current common sizes of batteries. This is a list of the sizes, shapes, and general characteristics of some common primary and secondary in household, automotive and light industrial use. The complete no. Coin-shaped cells are thin compared to their diameter. is usually stamped on the metal casing. The IEC prefix "CR" denotes lithium manganese dioxide chemistry. Since LiMnO2 cells pro. are generally not interchangeable with using a different chemistry, due to their higher voltage. Many are also available with that can increase their ph.
