Frequently Asked Questions
Q
What is the daily production capacity for these bridge-riveted battery spring contacts?
Our fully automated production lines are capable of producing over 2 million sets per day, supported by more than 40 sets of self-developed intelligent equipment dedicated to the bridge riveting process.
Q
What materials are available for the AA battery contact springs?
We offer AA battery contact springs in various materials. The standard model (055D) uses SPCC combined with steel wire, with nickel plating as the surface treatment. Different material options correspond to salt spray test durations of 24, 48, or 72 hours to suit varying application requirements.
Q
Are these battery connectors suitable for automated assembly lines?
Yes. The bridge riveting structure ensures exceptional spring stability, and the high dimensional accuracy of each connector (18.5 × 16.7 mm) allows for quick and precise alignment in automated assembly environments, significantly improving overall production efficiency.
Q
What quality and environmental certifications do these products hold?
All products comply with RoHS and REACH environmental standards. In addition, every plated batch undergoes mandatory solderability testing, and each unit passes a 24-hour neutral salt spray test to ensure long-term corrosion resistance and reliable electrical performance.
Q
What makes the bridge-riveted design superior to conventional spring contacts?
The bridge riveting process is entirely hands-free and fully automated, eliminating human error and ensuring consistent quality. This design provides secure spring retention, superior metal flatness, and high verticality — all critical factors for reliable electrical contact in battery-powered devices.
Q
Can I request customized specifications or surface treatments for these connectors?
Yes. We offer flexible options including different material grades and surface treatments, each corresponding to specific salt spray test performance levels (24H, 48H, or 72H). Please contact our team with your specific application requirements so we can recommend the most suitable solution.
