Frequently Asked Questions
Q
What is the daily production capacity of the 3 springs 18650 battery connector?
Our fully automated production line, powered by over 40 self-developed intelligent machines and bridge riveting technology, achieves a daily production capacity of 2 million+ sets — an industry-leading output that ensures reliable supply for large-scale orders.
Q
What corrosion resistance levels are available for the 18650 battery contact springs?
We offer professional grading for different corrosion resistance requirements. Depending on the material combination selected, our contacts can pass 24-hour, 48-hour, or 72-hour neutral salt spray tests. Each plated batch also comes with a solderability test report to ensure consistent performance.
Q
What materials are used in the 3 springs 18650 battery connector (Model 161F)?
The connector is made from SPCC (cold-rolled steel) combined with steel wire springs. The surface is treated with nickel plating to enhance conductivity, corrosion resistance, and solderability.
Q
How does bridge riveting technology solve spring detachment and alignment issues?
Our bridge riveting process securely locks the spring contacts in place, eliminating detachment risks during assembly or use. The method also ensures high verticality and flatness of the contacts, which is critical for accurate automated assembly and consistent electrical performance.
Q
Are these battery connectors compliant with environmental regulations?
Yes. Our 3 springs 18650 battery connectors are fully compliant with RoHS and REACH environmental certifications, making them suitable for export to European markets and other regions with strict environmental standards.
Q
What are the key dimensions and specifications of the Model 161F connector?
The Model 161F 3 springs 18650 battery connector measures 31.45 × 31.45 mm. It features nickel-plated SPCC and steel wire construction, passes a 24-hour neutral salt spray test, and is produced entirely through automated processes for consistent dimensional accuracy and quality.
