Our unique sealing technology and materials with excellent heat resistance have dramatically improved the operating temperature range.
It is the most suitable battery for in-vehicle use such as power supply for TPMS (tire pressure monitoring system) sensor.
It is also being used in IoT sensors and HACCP temperature loggers, which require a wide operating temperature range.
Wide operating temperature range: -40 ° C to + 125 ° C *
CR2450HR-Ex can operate up to 150 ℃ depending on the conditions
Excellent liquid leakage resistance even under high temperature and acceleration conditions
Can operate even under acceleration of 2000G (equivalent to 300km / h driving)
Maintains electrical characteristics even when exposed to high temperature or humid atmosphere for a long time
- When using at 85 ° C or higher, please check with us the conditions of use.
We sell heat-resistant coin-type lithium manganese dioxide batteries (CR batteries) to equipment manufacturers only as parts for incorporation into equipment. Therefore, it is not possible to sell replacement batteries directly to customers who use equipment with a heat-resistant coin-type lithium manganese dioxide battery (CR battery) without going through the equipment manufacturer. If you want to replace the heat-resistant coin-type lithium manganese dioxide battery (CR battery) installed in your current device, please contact the manufacturer of each device.
If you would like to use a heat-resistant coin-type lithium manganese dioxide battery (CR battery) as an embedded component, please contact us.

UL parts certified as qualified products
The heat-resistant coin-type lithium manganese dioxide battery is UL LLC component certified. (Technician Replaceable)
Approved varieties: CR2450HR, CR2450HR-Ex, CR2050HR, CR2032HR, CR2032HRS
Authorization number: MH12568
Principle and reaction
The heat-resistant coin-type lithium manganese dioxide battery uses manganese dioxide as the positive electrode active material and lithium as the negative electrode active material, and uses an organic electrolyte.
High temperature storage characteristics
Capacity deterioration due to high temperature (80 ° C) storage is very small compared to normal CR
High temperature and high humidity storage characteristics
Deterioration of internal resistance due to storage in a humidified atmosphere (60 ° C 90% RH) is very small compared to normal CR
Heavy load characteristics
