Lithium cylindrical type batteries (CR series/standard type)
User-replaceable Lithium batteries
These CR series standard Lithium cylindrical batteries feature a good pulse discharge capability, an operating temperature range of -40°C to +70°C, a self-discharge rate at 20°C of just 1.0% per year and a stable operating voltage. Our batteries can power applications such as medical equipment, door locking systems, marine devices, sanitary equipment, high energy flashlights etc.
Features
- Good pulse discharge capability
- Operating temperature range: between -40°C to +70°C
- Self-discharge rate at 20°C just 1.0% per year
- Stable operation voltage

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
