Product Introduction
Our 2 springs 18650 battery spring contacts feature a durable bridge-riveted design and are manufactured using fully automated processes, ensuring a daily production capacity of over 2 million units. They are characterized by their secure spring retention, high verticality, and superior metal flatness. Furthermore, these contacts demonstrate excellent weldability and have passed a rigorous 24-hour neutral salt spray test, guaranteeing reliability and longevity.
Frequently Asked Questions
Q
What is a bridge-riveted 18650 battery connector and what makes it different from standard battery contacts?
A bridge-riveted 18650 battery connector uses a structural riveting method to securely bond the spring to the base plate. Unlike standard press-fit or welded contacts, the bridge-riveted design guarantees that springs never detach during use, maintains precise vertical installation alignment, and delivers consistently flat metal surfaces — all critical requirements for stable, high-speed automated assembly lines.
Q
What materials are used in the 2 springs 18650 battery connector (Model 177L)?
The Model 177L connector is made from SPCC (cold-rolled steel sheet) combined with steel wire for the spring elements. The surface is finished with nickel plating to enhance electrical conductivity, prevent oxidation, and ensure long-term corrosion resistance. All materials comply with RoHS and REACH environmental standards.
Q
What corrosion resistance grades are available, and how is salt spray testing conducted?
Multiple corrosion resistance grades are offered to suit different application environments: 24-hour, 48-hour, and 72-hour neutral salt spray test ratings are all available. Each plated production batch must pass a solderability test checkpoint before it is approved for shipment, ensuring that every unit maintains stable electrical performance and surface integrity throughout its service life.
Q
How is production quality controlled throughout the manufacturing process?
Quality is fully controllable from raw material selection through to final inspection. The bridge-riveting process is performed entirely by over 40 units of self-developed intelligent equipment, eliminating human error and the variability associated with manual riveting. Each production stage — including material input, plating, riveting, and final inspection — is monitored and recorded to ensure consistent dimensional accuracy and surface quality.
Q
What is the daily production capacity, and can large-volume orders be fulfilled reliably?
The fully automated production line, supported by over 40 dedicated smart machines, enables a daily output exceeding 2 million sets. This large-scale capacity ensures reliable fulfillment of high-volume purchase orders with consistent lead times and stable quality, making it suitable for mass-production supply chains in the consumer electronics, power tools, and energy storage sectors.
Q
Are these battery connectors compliant with international environmental certifications?
Yes. The 2 springs 18650 battery connector meets both RoHS (Restriction of Hazardous Substances) and REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) regulatory requirements. This makes the product eligible for use in products sold across the European Union and other regions with strict environmental compliance requirements, supporting your global market access needs.
