Frequently Asked Questions
Q
What makes the 3 springs 18650 battery connector different from manually assembled connectors?
Our connectors are produced using a fully automated bridge-riveting process powered by 40+ self-developed smart machines. This eliminates manual handling errors, ensures consistent high verticality and flatness, and enables a daily output of over 2 million units — far exceeding typical manual production benchmarks.
Q
What corrosion resistance levels are available for these battery contact springs?
We offer professional grading based on corrosion resistance requirements. Different material combinations allow our 18650 battery contact springs to pass 24-hour, 48-hour, or 72-hour neutral salt spray tests, catering to a wide range of application environments.
Q
What materials and surface treatments are used in the 161F model?
The 161F model is made from SPCC combined with steel wire and features a nickel plating surface treatment. This combination delivers strong mechanical performance, reliable conductivity, and solid corrosion resistance suitable for standard 18650 battery applications.
Q
How is solderability quality assured for each production batch?
Every plated batch undergoes a dedicated solderability test, and a corresponding test report is provided. This ensures that each shipment meets consistent weldability standards and gives customers full traceability and confidence in the product's performance.
Q
Does the 18650 battery connector comply with environmental regulations?
Yes. Our 3 springs 18650 battery connector has passed both RoHS and REACH certifications, confirming that it is free from restricted hazardous substances and meets international environmental compliance standards for global markets.
Q
How does the bridge-riveted design solve spring detachment and alignment issues?
The bridge-riveting process mechanically locks the spring contact in place, preventing detachment during assembly or use. The automated riveting also guarantees precise alignment, resulting in high verticality and flatness that supports seamless integration into automated battery assembly lines.
