Frequently Asked Questions
❓
What is bridge riveting and why is it used in AAA battery contact springs?
Bridge riveting is a specialized joining process that permanently interlocks components without welding or adhesives. In AAA battery contact springs, it prevents detachment during repeated insertion and removal cycles, ensures high verticality and flatness, and supports consistent automated assembly performance.
❓
What is the daily production capacity for these battery contact springs?
With our fully automated intelligent production lines and over 40 dedicated high-efficiency machines, we achieve a stable daily production capacity of more than 2 million sets of battery contact springs, enabling reliable large-scale supply for customers worldwide.
❓
What salt spray protection levels are available for the universal AAA battery contact springs?
Our universal AAA battery contact springs offer multiple material options corresponding to 24-hour, 48-hour, or 72-hour neutral salt spray protection levels. Each plated batch undergoes soldering tests to ensure excellent and reliable solderability.
❓
What certifications do these AAA battery connectors comply with?
Our AAA battery connectors comply with both RoHS (Restriction of Hazardous Substances) and REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) environmental certifications, meeting international standards for eco-friendly and safe electronic components.
❓
What models and dimensions are available for the universal AAA battery connector?
We offer two standard models: 045D and 045L. The available specifications and dimensions are 10×9mm and 21.6×9mm. Both models are made from SPCC steel with steel wire and feature a nickel-plated surface treatment for corrosion resistance.
❓
How does fully automated production benefit the quality of battery contact springs?
Fully automated production eliminates inconsistencies caused by manual handling, ensuring every spring contact meets precise dimensional tolerances for verticality and flatness. This results in superior weldability, more stable product performance, and smoother automated device assembly across all batches.
