characteristic

• Light weight, high voltage, high energy density
The battery voltage of 3V is about twice that of the dry battery. So far, two batteries are needed. Now one battery is enough to save space and realize lightweight.

• Superior discharge stability
Even if it is discharged for a long time, it can also display stable voltage characteristics, so it can improve the reliability of the equipment and save the maintenance of battery replacement.

• Wide operating temperature range
The working temperature range of the standard type is − 30 ℃~70 ℃, while that of the quasi heat-resistant type is extended to − 40 ℃~85 ℃. The upper limit of operating temperature of electronic components and ICs is not more than 85 ℃, which can support these products. In addition, as for the storage characteristics, the quasi heat-resistant type can also reduce the voltage drop compared with the standard type when it is stored at 85 ℃ for more than 100 days.

• Maximum capacity of button type lithium battery*1
The "CR3677X" * 2 with the largest capacity in the quasi heat resistant type and the button type lithium battery with the largest capacity * 1 not only have larger nominal capacity than the CR123A battery and CR2 battery, but also contribute to the miniaturization and thinness of electronic equipment.

*1 Our investigation in October 2018

*2 CR3677X production is expected at the end of 2019

• Superior liquid leakage resistance
By using the newly developed battery structure and electrolyte, it has excellent leakage resistance for a long time.

• Superior preservation characteristics
Active substances and electrolytes have the characteristics of less self discharge due to strict selection of substances with high stability and unique packaging technology. Compared with the nominal capacity, the self discharge capacity under normal temperature and humidity is less than 1% in a year.

• UL components certified as qualified products
Murata's button type lithium manganese dioxide battery is UL component certified. （UL1642 File No. MH12566）

• EU Battery Directive ・ RoHS Directive:
The battery does not contain three substances (mercury, cadmium and lead) specified in the EU battery directive, meeting this standard. The battery is outside the RoHS command object.
