❓ Frequently Asked Questions
Q
What is a bridge-riveted AA battery connector and what makes it different from standard contacts?
A bridge-riveted AA battery connector uses a riveting technique that mechanically joins the spring to the base plate, providing stronger retention compared to standard welded or pressed contacts. This design significantly reduces the risk of spring detachment during use, improves verticality, and results in superior metal flatness — all of which contribute to a smoother automated assembly process and longer product lifespan.
Q
What is the daily production capacity for these AA battery connectors?
With over 40 dedicated, fully automated machines and self-developed smart equipment, our daily production capacity exceeds 2 million units. The entire bridge riveting process is hands-free, ensuring consistent quality at high volumes without manual intervention.
Q
What corrosion resistance levels are available, and how are they tested?
Our universal AA battery connectors are available in multiple material compositions to meet different corrosion resistance requirements. They are capable of passing 24-hour, 48-hour, or 72-hour neutral salt spray tests (NSS) in accordance with standard testing procedures. Every batch of plated contacts also undergoes solderability testing to ensure consistent welding performance.
Q
What materials and surface treatments are used for these battery connectors?
The connectors are made from SPCC (cold-rolled steel sheet) combined with steel wire for the spring contact. The surface treatment applied is nickel plating, which provides excellent conductivity, corrosion resistance, and solderability. Both the 173D and 173L models are available in dimensions of 13×11mm and 28.8×11mm respectively.
Q
Are these AA battery connectors compliant with environmental and safety certifications?
Yes. Our universal AA battery connectors comply with both RoHS (Restriction of Hazardous Substances) and REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) regulations. These certifications ensure that the products are free from harmful substances and are safe for use in consumer electronics and other regulated applications worldwide.
Q
Can these battery connectors support high-speed automated assembly lines?
Absolutely. The bridge-riveted spring design is specifically engineered to support automated assembly. The high verticality and superior metal flatness of each connector ensure precise and consistent positioning on automated production lines, minimizing jamming or misalignment. This makes them an ideal choice for manufacturers who require both high throughput and consistent product quality.
