The coin-type lithium manganese dioxide battery (CR battery) is a compact, lightweight battery with an operating voltage of 3V and a wide operating temperature range.
It is widely used as a power source for IoT sensors and medical devices, and as a power source for various electronic devices such as distribution tags and wearable devices.
Shows stable operating voltage with light load discharge over a long period of time.
3V (nominal voltage), which is about twice that of alkaline button batteries and silver oxide batteries. It is a battery with high energy density.
Uses a highly conductive electrolyte. It lowers the internal resistance and provides a stable operating voltage.
For this reason, there is little change in the operating voltage not only at room temperature but also at low and high temperatures, and stable power is demonstrated.
Uses an organic electrolyte that does not easily leak. It has excellent liquid leakage resistance compared to battery systems that use alkaline electrolytes.
In addition, the highly sealed sealing structure and sealant treatment achieve an annual self-discharge rate of approximately 1%.
The coin-type lithium manganese dioxide battery is UL LLC part certified.
In addition, we have also obtained user replayable certification.
