Lithium coin type batteries (CR series)
Lithium batteries - designed for high current demanding applications
Panasonic's Lithium CR coin type batteries feature a good pulse capability, offer a stable voltage level during discharge, long term reliability, a temperature range of -30°C to +85°C, and a self-discharge rate at 20°C of just 1.0% per year. Our batteries can power applications such as remote keyless entry (RKE), meters, medical equipment, vending machines, price tags etc.

Lithium CR series coin - inside the battery
Do you want to look inside a lithium coin type battery? This 3D graphic shows the inner working of such a device and gives an excellent overview of the battery's materials (electrodes, gasket, insulator, poles, etc.).
1 Negative pole
2 Anode (lithium)
5 Positive pole (cell can)
6 Cathode (manganese dioxide)
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 (some exceptions will be encountered). This numbering system is supported by the Japan International Standard Committee of Clocks and Watches and is also an established practice in Japan.
CR - 2032
C- manganese dioxide lithium battery
20-battery diameter (in mm)
32- divide this number by 10 to obtain the battery height (in mm)
