China Suppliers Factory for Fully Automated AA Battery Connectors - High-Quality, Reliable, and Zero Spring Detachment
Product Application
Automated Assembly
Application
We rely on self-developed intelligent production equipment as the core, adopting bridge riveting technology to ensure fully automated and highly consistent spring assembly. More than 40 machines operate in coordination, supporting a robust daily delivery capacity of over 2 million sets.
Secure & Reliable
Application
Using bridge riveting technology, the spring remains secure and never loosens. Strict control over verticality and flatness provides reliable support for automated assembly.
Application
Every model of universal AA battery contact spring is developed through strict material and process selection, achieving tiered salt spray corrosion resistance of 24, 48, or 72 hours. Additionally, each plated batch is required to pass solderability testing to validate its performance.

Frequently Asked Questions
Q
What is bridge riveting technology, and why is it used in these AA battery connectors?
Bridge riveting technology is a precision joining method that permanently secures the spring to the contact base without the use of adhesives or additional fasteners. It ensures the spring never loosens during use, maintains consistent verticality, and delivers superior metal flatness — all of which are critical for reliable automated battery assembly.
Q
What is the daily production capacity for these universal AA battery connectors?
Our facility operates more than 40 dedicated self-developed smart machines in full coordination, achieving a robust daily production capacity of over 2 million sets. The fully automated production line ensures consistent quality and supports high-volume order fulfillment.
Q
What materials and surface treatments are used for these battery connectors?
The connectors are made from SPCC (cold-rolled steel) combined with steel wire, offering excellent mechanical strength and conductivity. The surface is treated with nickel plating, which provides corrosion resistance, improved solderability, and a clean contact surface. Each plated batch must pass solderability testing before shipment.
Q
What corrosion resistance levels are available, and how are they tested?
Our universal AA battery contact springs are available in tiered salt spray corrosion resistance grades of 24 hours, 48 hours, or 72 hours, depending on the model and application requirements. All products undergo neutral salt spray testing (NSS) in accordance with standard test methods to validate their corrosion performance.
Q
Are these AA battery connectors compliant with environmental regulations?
Yes. All of our universal AA battery connectors have obtained both RoHS and REACH eco-certifications. This ensures that the products are free from hazardous substances restricted by European Union directives and are safe for use in consumer electronics and other regulated applications worldwide.
Q
Which models are available, and what are their dimensions?
Two models are currently available: Model 027D with dimensions of 14×12mm, and Model 027L with dimensions of 29.6×12mm. Both models share the same SPCC + steel wire construction and nickel-plated surface treatment, making them suitable for a wide range of AA battery-powered devices with different contact spacing requirements.
