OEM Custom Battery Contacts for AG13, CR2032, CR2450 Coin Cells - China Suppliers & Factory Quality Phosphor Bronze and Steel Stamping Exporter, Quotes

Shenzhen Sunmy Hardware Co.,Ltd. is a leading manufacturer specializing in precision engineering for electronic components. Our custom battery contacts are expertly crafted from high-grade phosphor bronze and spring steel using advanced stamping techniques. These components are meticulously designed to provide reliable electrical connectivity, ensure secure battery retention, and withstand fatigue in demanding applications. We offer fully customizable solutions for standard coin cells like AG13/LR44, CR2032, and CR2450, ensuring perfect integration into your product's design.

From consumer electronics and medical devices to industrial sensors and toys, our custom-stamped battery contacts provide a robust and cost-effective connection solution. Leverage our extensive experience and powerful development capabilities to create a tailored component that meets your exact performance and dimensional requirements.

We utilize state-of-the-art sheet metal & stamping technology to produce our custom battery contacts. This process begins with precise die design and fabrication, leveraging our internal capabilities for custom tooling. Material selection is critical; we offer both phosphor bronze for excellent conductivity and corrosion resistance, and high-tensile spring steel for superior spring characteristics and structural strength, often coated for enhanced performance.

High-speed, multi-stage stamping presses accurately cut, bend, and form the complex geometry of the battery contact from continuous metal strips. This progressive stamping approach guarantees exceptional consistency, tight tolerances, and high production efficiency, even for large volumes. Our post-processing options include precise nickel plating, gold plating, or other surface treatments for optimal solderability, corrosion protection, and contact reliability. Every step is overseen by our rigorous quality control system to ensure error-free products.
