Frequently Asked Questions
What is bridge riveting technology and why does it matter for AAA battery connectors?
Bridge riveting is an advanced fastening technique that permanently secures the spring to the contact base, ensuring it never detaches during use or automated assembly. This method eliminates the risk of spring separation, improves structural integrity, and significantly enhances the reliability and yield rate of automated production lines.
What is the daily production capacity for these universal AAA battery connectors?
Using over 40 dedicated machines equipped with self-developed intelligent automation systems, our facility maintains a stable daily production capacity of more than 2 million sets, ensuring consistent quality output and reliable delivery schedules for large-volume orders.
What materials and surface treatments are used for these battery spring contacts?
The universal AAA battery connectors are made from SPCC steel combined with a steel wire spring. The surface treatment applied is nickel plating, which provides excellent corrosion resistance and reliable electrical conductivity, while meeting the required 24-hour neutral salt spray test standards.
Are these AAA battery connectors compliant with environmental and safety regulations?
Yes. These battery spring contacts are fully certified under both RoHS (Restriction of Hazardous Substances) and REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) regulations, ensuring they meet international environmental and safety compliance requirements for global markets.
How is solderability quality assured across production batches?
Each electroplated batch undergoes mandatory solderability testing before release. This batch-level quality control process guarantees that every shipment performs consistently in soldering applications, reducing the risk of defects during your downstream manufacturing processes.
What size variants are available for the universal AAA battery connector?
The universal AAA battery connectors are available in two models: Model 174D with dimensions of 9.8×8.5mm (negative terminal cap contact) and Model 174L with dimensions of 21.4×8.5mm (positive terminal spring contact). Both models support various material combinations to meet different salt spray test requirements of 24H, 48H, or 72H.
