Frequently Asked Questions
Q
What is the daily production capacity of your AA battery connectors?
Our production line leverages over 40 sets of self-developed intelligent equipment with fully automated bridge riveting processes, achieving a daily production capacity exceeding 2 million sets, ensuring reliable and timely supply for large-scale procurement needs.
Q
What materials are used in the universal AA battery connector (Model 055D)?
The Model 055D universal AA battery connector is made from SPCC (cold-rolled steel) combined with steel wire, and features a nickel-plating surface treatment to ensure superior conductivity and corrosion resistance.
Q
What salt spray test options are available for AA battery contact springs?
We offer AA battery contact springs in various material grades, supporting 24-hour, 48-hour, or 72-hour neutral salt spray tests respectively. Customers can select the appropriate specification based on their application environment and reliability requirements.
Q
Are your battery connectors compliant with RoHS and REACH regulations?
Yes. All our AA battery connectors, including the Model 055D, have obtained both RoHS and REACH eco-certifications, meeting international environmental and safety standards for use in consumer electronics and industrial applications worldwide.
Q
How does the bridge-riveted design benefit spring stability and assembly?
The bridge-riveted structure mechanically locks the spring in place, eliminating loosening risks during high-vibration or high-cycle operations. Combined with high dimensional accuracy (18.5 × 16.7 mm), it guarantees precise, quick alignment in automated assembly lines, significantly improving overall production efficiency and product consistency.
Q
Is solderability testing performed on all plated batches?
Yes. Every plated production batch undergoes strict solderability testing to verify that the nickel-plated surface meets the required wetting and bonding standards. This ensures consistent, reliable solderability across all delivered products, giving you full confidence in downstream assembly processes.
