Frequently Asked Questions
Q
What is the bridge-riveting process and why is it important for AAA battery contact springs?
The bridge-riveting process is a structural joining method that permanently secures the spring component to the contact base, preventing detachment during use. It delivers higher verticality and flatness compared to traditional methods, resulting in more stable automated assembly lines and longer product service life.
Q
What is your daily production capacity for universal AAA battery contact springs?
Backed by over 40 dedicated high-efficiency machines and fully automated production lines, our facility achieves a stable output of more than 2 million sets of AAA battery contact springs per day, ensuring reliable large-scale supply for our global customers.
Q
What salt spray protection levels are available for these battery contact springs?
We offer multiple material and plating options to accommodate different corrosion resistance requirements. Depending on the selected configuration, our springs can achieve neutral salt spray test ratings of 24 hours, 48 hours, or 72 hours, allowing customers to choose the right protection level for their specific application environment.
Q
What certifications do your AAA battery contact springs comply with?
Our universal AAA battery contact springs are fully compliant with RoHS and REACH environmental regulations, ensuring they are free of restricted hazardous substances. These certifications make them suitable for use in products sold in the European Union and other markets with strict environmental requirements.
Q
How do you ensure solderability quality for every production batch?
We implement mandatory soldering tests for every single plated batch of our battery contact springs. This quality control measure verifies that each batch meets our solderability standards before shipment, guaranteeing consistent and reliable electrical connections in the end-use assembly.
Q
Which models and dimensions are available for the universal AAA battery connector?
We currently offer two standard models: the 045D with dimensions of 10×9mm, and the 045L with dimensions of 21.6×9mm. Both models are made from SPCC steel combined with steel wire and feature a nickel-plated surface treatment. Custom specifications may be available upon request for high-volume orders.
