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.

• The maximum pulse discharge current is about twice of the original
Compared with the standard type, the "high current type" can maintain a high current value even if the discharge is accelerated. Increase the maximum pulse discharge current * 1 to 50mA, which is about twice of the "standard type". LPWA communication equipment such as "LoRa", which used to be difficult to use button type lithium battery and has a high peak current, can also be used*2.
*1 Under the condition of discharging to 50% of the nominal capacity, the maximum current value of pulse discharge with voltage above 2V (3 seconds) at 23 ℃

*2 It may vary depending on the use environment and conditions

• Discharge time of capacity utilization is about 3 times of the original*3
Compared with the standard type, because the battery capacity can be effectively used, the high voltage can be maintained even if the discharge is accelerated. When used by IoT equipment, one battery exchange can be used for a long time, greatly reducing the battery replacement frequency. It improves the stability of data collection and the reliability of the system, thus reducing the management cost.

*3 Pulse discharge conditions for discharging for 3 seconds and stopping for 33 seconds at 45 mA under 23 ℃

• 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.
