POS Machine

Commercial POS devices operate in diverse scenarios with long-term standby operation and large ambient temperature differences. They generally adopt a power supply architecture combining main power input and 3V button battery backup power.

These devices require long-term micro-current standby, instant pulse discharge, wide temperature resistance, high durability and maintenance-free performance.

3V lithium manganese button batteries such as CR2032 and CR2450 serve as essential supporting power sources to ensure the stable operation of POS systems.
