How to read the model numbers used for Lithium batteries

As a general rule the model number contains two capital letters and one or more digits as shown in the example, (exceptions can occur). This numbering system is supported by the Japan International Standard Committee of Clocks and Watches and is also an established practice in Japan.

CR - 123A

C- manganese dioxide lithium battery
R 123- battery size
A- battery diameter
