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, (variations can be expected). This numbering system is supported by the Japan International Standard Committee of Clocks and Watches and is an established practice in Japan.

ML - 1220

M- manganese lithium battery
L- round
12- battery diameter (in mm)
20- divide this by 10 to obtain the battery height (in mm)
