Frequently Asked Questions
What is bridge riveting technology, and why is it used in AA battery spring contacts?
Bridge riveting technology is a specialized assembly method that permanently secures the spring to the contact base, ensuring it never loosens during use. It enables precise control over verticality and flatness, which is critical for consistent electrical contact and reliable automated assembly in battery-powered devices.
What is the daily production capacity for these universal AA battery connectors?
Using more than 40 dedicated machines operating in coordination with our self-developed intelligent equipment, we maintain a daily production capacity of over 2 million sets. This scale supports high-volume procurement needs with consistent on-time delivery.
What surface treatment is applied, and how does it perform in corrosion resistance tests?
The contacts undergo nickel plating as the surface treatment. They are tested with a neutral salt spray test and achieve tiered corrosion resistance levels of 24, 48, or 72 hours depending on the model. Each plated batch is also required to pass solderability testing before shipment.
What models and dimensions are available for the universal AA battery connector?
Currently, two standard models are available: Model 027D with dimensions of 14×12mm, and Model 027L with dimensions of 29.6×12mm. Both models are made from SPCC steel combined with steel wire and are produced using fully automated processes.
Are these AA battery spring contacts compliant with environmental and safety certifications?
Yes. All universal AA battery connectors are fully compliant with both RoHS and REACH environmental regulations. These certifications ensure that the products are free from hazardous substances and meet international standards for safe use in consumer electronics and industrial applications.
What are the key quality advantages of these spring contacts compared to conventional designs?
These spring contacts offer several advantages: the bridge-riveted structure ensures the spring stays permanently secured with no risk of loosening; strict verticality and flatness tolerances guarantee consistent contact performance; fully automated production eliminates human error; and each batch undergoes both salt spray and solderability testing to validate long-term reliability and weldability.
