Frequently Asked Questions
1
What is the daily production capacity of your AA battery spring contacts?
Our fully automated production lines, supported by over 40 sets of self-developed intelligent equipment, deliver a daily production capacity exceeding 2 million sets of spring contacts, ensuring reliable supply for high-volume orders.
2
What materials are available for the AA battery contact springs?
The standard model (055D) is made from SPCC + steel wire with nickel plating. We also offer variants in different materials to meet varying salt spray test requirements — 24H, 48H, or 72H — depending on your application environment.
3
What environmental certifications do your battery connectors comply with?
Our AA battery connectors are fully compliant with RoHS and REACH environmental regulations, making them suitable for use in global markets with strict environmental standards.
4
How is solderability quality ensured in your plated spring contacts?
All plated production batches undergo mandatory solderability testing before shipment. This ensures consistent and reliable weldability across every batch, reducing the risk of assembly defects on your production line.
5
What is the bridge riveting process and what are its advantages?
The bridge riveting process is a specialized spring assembly technique where the spring is securely locked to the contact plate via a riveted bridge structure. This ensures superior spring retention, high verticality, and excellent metal flatness — all critical for maintaining stable electrical contact in battery-powered devices.
6
Are these battery connectors suitable for automated assembly lines?
Yes. The high dimensional accuracy (18.5 × 16.7 mm, Model 055D) and consistent quality of our bridge-riveted connectors make them ideal for various automated assembly scenarios. The precise dimensions allow for quick and accurate alignment, significantly improving overall production efficiency.
