The coin type lithium manganese dioxide battery (CR battery) is a small, lightweight battery with an operating voltage of 3V and the ability to operate over a wide temperature range. It has a wide range of applications for powering devices such as various IoT sensors, medical equipment, data loggers and wearable device

Maxell’s original sealing technology and highly heat-resistant material expands operating temperature range remarkably, making the batteries supremely suitable for automobile applications — for powering TPMS (Tire Pressure Monitoring System) sensors, for example. The range of technologies where these batteries can be applied is expanding to include IoT sensors and HACCP temperature loggers that require a wide operating temperature range.
