Frequently Asked Questions
Q
What is bridge riveting technology, and why is it used in AA battery connectors?
Bridge riveting technology is a precision assembly method that permanently secures the spring to the contact base without loosening. It ensures a stable mechanical connection with high verticality and flatness, making it ideal for automated battery assembly lines that require consistent and reliable electrical contact.
Q
What is the daily production capacity for these universal AA battery connectors?
With over 40 self-developed smart production machines operating in coordination, our facility achieves a daily production and delivery capacity of more than 2 million sets, ensuring scalable supply for both small and large-volume orders.
Q
What surface treatment is applied to the AA battery connectors, and what corrosion resistance do they offer?
The connectors are finished with nickel plating and have passed a 24-hour neutral salt spray test. Depending on the model and application requirements, tiered corrosion resistance levels of 24, 48, or 72 hours are achievable, providing long-term durability in various operating environments.
Q
What materials are used in the universal AA battery connector?
The connectors are made from SPCC (cold-rolled steel) combined with steel wire. This material combination ensures both the structural rigidity of the base and the appropriate spring-back force of the contact spring, meeting performance demands for long-term use.
Q
Are these battery connectors compliant with environmental regulations?
Yes. Our universal AA battery connectors are certified to both RoHS and REACH standards, confirming that hazardous substances are controlled within regulated limits. This makes them suitable for global markets including the EU, North America, and other regions with strict environmental compliance requirements.
Q
What models are available and what are their dimensions?
Two standard models are available: Model 027D with dimensions of 14×12mm and Model 027L with dimensions of 29.6×12mm. Both models are manufactured using fully automated processes and share the same core material, surface treatment, and quality standards, offering flexibility for different battery holder designs.
