Frequently Asked Questions
What is the daily production capacity of your universal AA battery connectors?
Our production facility operates with over 40 dedicated smart machines working in coordination, enabling a daily delivery capacity of more than 2 million sets to meet large-scale supply demands.
What is bridge riveting technology, and why is it used in AA battery spring contacts?
Bridge riveting is a precision assembly technology that securely fastens the spring to the contact plate without loosening. It ensures high verticality and superior metal flatness, which are critical for reliable automated battery assembly and consistent electrical contact performance.
What materials are used to manufacture the universal AA battery connector?
The connectors are made from SPCC (cold-rolled steel) combined with steel wire, providing excellent mechanical strength and conductivity. The surface is treated with nickel plating to enhance corrosion resistance and solderability.
What corrosion resistance standards do your AA battery spring contacts meet?
Every model undergoes a tiered neutral salt spray test with resistance ratings of 24, 48, or 72 hours, depending on the specification. Each plated batch must also pass solderability testing to ensure consistent performance and long-term reliability.
Are your AA battery connectors RoHS and REACH compliant?
Yes. All our universal AA battery connectors carry both RoHS and REACH eco-certifications, confirming that they are free from hazardous substances and compliant with international environmental regulations for use in global markets.
What models and dimensions are available for the universal AA battery connector?
We currently offer two standard models: 027D and 027L. Their respective dimensions are 14×12mm and 29.6×12mm, making them compatible with a wide range of AA battery-powered devices and automated assembly lines.
