Frequently Asked Questions
What is the daily production capacity for your AAA battery contact springs?
Our fully automated production lines, supported by over 40 dedicated high-efficiency machines, enable a stable daily output of more than 2 million sets of AAA battery contact springs, ensuring reliable large-scale supply for our customers.
What makes the bridge riveting process superior to traditional methods?
The bridge riveting process effectively prevents spring detachment during use, achieving high verticality and superior metal flatness. This results in more stable production quality and significantly smoother automated assembly compared to traditional manual riveting methods.
What material options and salt spray protection levels are available?
We offer multiple material options corresponding to 24-hour, 48-hour, or 72-hour neutral salt spray protection levels. The standard model features SPCC + steel wire with nickel plating and a 24-hour salt spray rating, while higher protection levels are available based on your application requirements.
Do your battery contact springs comply with environmental certifications?
Yes. All our universal AAA battery connectors are compliant with both RoHS and REACH environmental regulations, ensuring they meet international standards for restricted hazardous substances and are suitable for global markets.
How do you ensure consistent solderability across production batches?
We perform mandatory soldering tests on every plated batch without exception. This strict quality control process guarantees that each batch of contacts meets excellent and reliable solderability standards before it is shipped to customers.
What models and dimensions are available for the universal AAA battery connector?
We currently offer two standard models: 045D and 045L. The corresponding dimensions are 10×9mm and 21.6×9mm respectively. Both models are manufactured with SPCC + steel wire and finished with nickel plating for consistent surface quality.
