Video: Lithium cylindrical batteries (BR series) for professionals
This Panasonic video shows the recommended applications for Lithium cylindrical batteries and the inner working of a Lithium cylindrical battery. It also gives an excellent overview of the battery materials (electrodes, gasket, insulator, poles, etc.). Take a look at our video!
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 be expected). This numbering system is supported by the Japan International Standard Committee of Clocks and Watches and is also an established practice in Japan.
BR - 1/2 AA
B - poly-carbon monofluride lithium battery
R - round
1/2 - battery size
AA - battery diameter (mm)
