Frequently Asked Questions
Q
What is bridge riveting, and why does it matter for AAA battery contact springs?
Bridge riveting is a specialized mechanical joining process that permanently secures the steel wire spring to the SPCC metal base without the need for welding or adhesives. This technique prevents detachment under repeated use, ensures high verticality and consistent flatness, and delivers a more stable and reliable connection — which is critical for automated assembly lines and long-service-life battery-powered products.
Q
What is the daily production capacity for your universal AAA battery connectors?
Our fully automated, self-developed intelligent production lines — supported by over 40 dedicated high-efficiency machines — enable a stable daily output of more than 2 million sets of battery contact springs. This guarantees consistent supply even for large-volume orders.
Q
What salt spray protection levels are available for these battery contact springs?
We offer multiple material and plating options that correspond to 24-hour, 48-hour, or 72-hour neutral salt spray protection levels. Our standard model passes a 24-hour neutral salt spray test. For applications requiring higher corrosion resistance, upgraded plating options are available. Every plated batch undergoes mandatory soldering tests to ensure reliable solderability before shipment.
Q
What are the available models and dimensions for the universal AAA battery connector?
The connectors are available in two models: 045D and 045L. Their respective dimensions are 10×9mm (045D) and 21.6×9mm (045L). Both are made from SPCC steel combined with a steel wire spring and finished with nickel plating to ensure good conductivity and corrosion resistance.
Q
Are your AAA battery spring contacts RoHS and REACH compliant?
Yes. Our universal AAA battery spring contacts are fully certified under both RoHS (Restriction of Hazardous Substances) and REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) regulations. These certifications confirm that no restricted hazardous substances are present, making our products suitable for global markets including the EU, North America, and other regions with strict environmental compliance requirements.
Q
How do fully automated production processes benefit buyers compared to manually assembled battery contacts?
Fully automated production eliminates human error, ensuring consistent dimensional accuracy, uniform surface treatment, and stable mechanical performance across every unit. For buyers, this translates into higher assembly yield rates, fewer defects, lower rejection rates on production lines, and predictable, reliable product quality — all critical factors for OEM and ODM partners in the battery and electronics industries.
