Frequently Asked Questions
Q What is bridge riveting technology, and why is it used in AA battery connectors?
Bridge riveting technology is a precision assembly method that mechanically locks the spring to the contact base, ensuring the spring never loosens during repeated use. It provides superior structural stability, consistent verticality, and reliable flatness — all critical for automated assembly lines and long-term product performance.
Q What is the daily production capacity for these universal AA battery connectors?
With over 40 self-developed intelligent production machines operating in coordination, our facility supports a daily delivery capacity of over 2 million sets, ensuring stable supply for high-volume customers and large-scale orders.
Q What salt spray corrosion resistance levels are available for these connectors?
Our universal AA battery contact springs are available in tiered salt spray corrosion resistance levels of 24 hours, 48 hours, and 72 hours, depending on the model and application requirements. Each option undergoes strict neutral salt spray testing to validate performance.
Q Are these AA battery connectors compliant with environmental regulations?
Yes. All models are certified to both RoHS and REACH standards, ensuring they are free from hazardous substances and fully compliant with international environmental regulations for electronics and consumer products.
Q What surface treatment is applied to the AA battery spring contacts?
The connectors are finished with nickel plating, which provides excellent corrosion resistance, improved solderability, and a uniform surface quality. Each plated batch is required to pass solderability testing to ensure consistent performance across every production run.
Q What models and dimensions are available for the universal AA battery connector?
Currently, two models are available: Model 027D with dimensions of 14×12mm, and Model 027L with dimensions of 29.6×12mm. Both are made from SPCC steel combined with steel wire and are manufactured using fully automated production processes to ensure consistent dimensional accuracy.
