Cooperation Case
POS Machine Product Collaboration -A&S584070 3.7v 2000mAh
Client Background
One of our long-term Korean clients was developing a new POS machine for their important customer. The client stated that the target market covers the globe, meaning the battery must possess multiple international certifications and meet specific capacity and size requirements.
Solution
Considering the client’s needs and aiming for the widespread global application of their device, we suggested adding PTC (Positive Temperature Coefficient) and NTC (Negative Temperature Coefficient) protection configurations. We understood that this would help the client enhance the safety reputation of their POS machine in the global market and facilitate business expansion.
Outcome & Value
The client approved this suggestion. After rigorous sample testing, they ultimately selected our 584070 3.7V 2000mAh battery. We then promptly assisted in initiating the application process for key certifications, including UL2054, CB, KC, CE, PSE, and UN38.3.
This battery, featuring high performance, high safety, and multiple certifications, not only met the client’s technical requirements but also served as a powerful support for their device entering the global market, further solidifying our deep cooperation with the client.
