Frequently Asked Questions
Q
What is bridge riveting and why is it used in these 18650 battery connectors?
Bridge riveting is an assembly method that permanently secures the springs to the metal contact plate without manual handling. This technique ensures that springs never detach during use or assembly, maintains precise vertical alignment, and produces consistently flat surfaces — all critical for reliable automated battery assembly lines.
Q
What is the daily production capacity for the 2 springs 18650 battery connectors?
Leveraging over 40 units of self-developed intelligent production equipment and a fully automated bridge riveting solution, the daily production capacity exceeds 2 million sets, ensuring consistent quality and fast delivery timelines for high-volume orders.
Q
What corrosion resistance options are available for the 18650 battery contact springs?
Multiple solutions are available based on corrosion resistance grade requirements: 24-hour, 48-hour, and 72-hour neutral salt spray tests. The standard Model 177L meets the 24-hour salt spray specification with nickel plating. Please contact us for upgraded plating options to meet higher corrosion resistance demands.
Q
Are these battery connectors RoHS and REACH compliant?
Yes. The 2 springs 18650 battery connectors are fully certified under both RoHS (Restriction of Hazardous Substances) and REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) regulations, making them suitable for use in consumer electronics and other environmentally regulated markets worldwide.
Q
How is solderability quality controlled during manufacturing?
Every plated batch is required to pass a dedicated solderability test checkpoint before proceeding to the next production stage. This in-process quality control ensures that each connector delivers stable and consistent soldering performance, reducing defect rates and improving end-product reliability.
Q
What are the key material and dimensional specifications of the Model 177L connector?
The Model 177L 18650 battery connector is constructed from SPCC steel sheet combined with steel wire springs, with an overall dimension of 36 × 17 mm. The surface is treated with nickel plating for corrosion protection and conductivity. These specifications make it well-suited for standard 18650 cylindrical cell battery holders and automated assembly equipment.
