Frequently Asked Questions
Q
What is the daily production capacity for the universal AAA battery contact springs?
Our fully automated production lines, supported by over 40 high-efficiency dedicated 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.
Q
What is the bridge riveting process, and why does it matter for battery connectors?
Bridge riveting is a key production technique that mechanically joins the spring and base without any manual operation. It prevents detachment during use, ensures high verticality and flatness, and enables smoother automated assembly in downstream manufacturing.
Q
What salt spray protection levels are available for your AAA battery contact springs?
We offer multiple material options corresponding to 24-hour, 48-hour, or 72-hour neutral salt spray protection levels, allowing customers to select the appropriate specification based on their product's environmental and durability requirements.
Q
What eco-certifications do your AAA battery connectors comply with?
Our universal AAA battery connectors are fully compliant with both RoHS (Restriction of Hazardous Substances) and REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) environmental standards, making them suitable for global export and use in eco-sensitive applications.
Q
How do you ensure consistent solderability quality across production batches?
We conduct soldering tests on every single plated batch of battery contact springs. This rigorous batch-level quality control ensures that every product delivered to our customers meets excellent and reliable solderability standards.
Q
What are the available models and dimensions for the universal AAA battery connector?
The universal AAA battery connector is available in two models: 045D and 045L. Their respective dimensions are 10×9mm and 21.6×9mm. Both models are made from SPCC combined with steel wire and feature a nickel-plated surface treatment.
