Frequently Asked Questions
Q
What is the daily production capacity for the universal AA battery connector?
Our production facility is equipped with over 40 self-developed smart machines operating in coordination, enabling a daily delivery capacity of over 2 million sets. This ensures prompt fulfillment of both large-scale and time-sensitive orders.
Q
What is bridge riveting technology, and why is it used for spring assembly?
Bridge riveting technology is a specialized joining process that mechanically locks the spring to the contact plate without the need for welding or adhesives. It ensures the spring remains permanently secure and never loosens during use, while also maintaining strict verticality and flatness — both of which are critical for reliable automated assembly.
Q
What salt spray corrosion resistance levels are available for these battery contacts?
Each model is developed through strict material and process selection, offering tiered salt spray corrosion resistance levels of 24, 48, or 72 hours. The standard model (027D / 027L) passes a 24-hour neutral salt spray test, and higher-grade options are available upon request.
Q
What material and surface treatment are used for the universal AA battery connector?
The connectors are made from SPCC (cold-rolled steel) combined with a steel wire spring component. The surface treatment applied is nickel plating, which enhances conductivity, corrosion resistance, and solderability. Each plated batch must pass solderability testing before shipment.
Q
Do the AA battery connectors comply with environmental regulations?
Yes. All universal AA battery connectors are certified to meet both RoHS (Restriction of Hazardous Substances) and REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) standards, ensuring they are safe for use in consumer electronics and compliant with global environmental requirements.
Q
What models and dimensions are available for the universal AA battery connector?
Two models are currently available: Model 027D (14×12mm) and Model 027L (29.6×12mm). Both are manufactured using fully automated bridge riveting processes, and both share the same material composition and surface treatment specifications. Custom dimensions may be available upon request.
