Frequently Asked Questions
What is bridge riveting technology, and why does it matter for AA battery connectors?
Bridge riveting technology is a specialized joining process that permanently secures the spring to the connector body, completely eliminating the risk of spring detachment during use. It also ensures superior verticality and flatness, which are critical for reliable automated assembly in battery-powered devices.
What is the daily production capacity for these AA battery connectors?
Our production line, consisting of over 40 dedicated smart machines, enables a daily output of more than 2 million sets. The entire bridge riveting process is fully automated with no manual intervention required.
What salt spray test standards do these connectors meet?
Our AA battery contact springs are designed to meet varying salt spray test durations — 24, 48, or 72 hours — depending on the material specification selected. The standard model (095L) passes a 24-hour neutral salt spray test, ensuring solid corrosion resistance for most consumer electronics applications.
What surface treatment is applied, and how is solderability ensured?
The connectors undergo nickel plating as the standard surface treatment. To guarantee consistent solderability, every plated batch is subjected to solderability testing before shipment, ensuring reliable solder joint performance in downstream assembly processes.
What environmental certifications do these battery connectors comply with?
These AA battery connectors are fully compliant with both RoHS and REACH environmental regulations, making them suitable for use in products sold in the European Union and other markets with strict environmental requirements.
What materials are used in the construction of the 095L AA battery connector?
The 095L model is constructed from SPCC (cold-rolled carbon steel sheet) combined with steel wire. This material combination provides a strong structural base while maintaining the spring elasticity required for consistent battery contact performance.
