Product Description
Micron-Precision Battery Springs & Contacts for Miniature and Implantable Devices
1.Battery Spring Quick Detail
In an era where miniaturization and high reliability are paramount, Tingfeng Hardware specializes in the precision manufacturing of miniature, high-precision battery springs and contacts. We have overcome the challenges of precisely forming sub-millimeter wires/strips, achieving micron-level dimensional control. Our core competency lies in deeply integrating "elastic mechanics" and "electrical contact science," providing battery connection solutions for your miniature devices (such as hearing aids, implantable device sensors, and high-end headphones) that are not only compact but also offer stable and reliable connections. Leveraging our proprietary precision molds and electroplating technology, along with IATF-level quality control processes, we ensure that every miniature product possesses exceptional reliability.
2.Battery Spring Product Description
When battery compartment space is compressed to the limit, every micron becomes crucial. We specialize in designing battery contacts for these "space-sensitive" applications. Our engineering philosophy is "innovation within constraints." We use finite element analysis (FEA) to optimize every bend in the contact spring, ensuring sufficient contact force while minimizing stress concentration. We study the wear characteristics of different plating materials at the microscopic level, selecting the combination that is most resistant to fretting corrosion. We even consider the trace gas emissions from batteries during long-term use, choosing corrosion-resistant materials. What we deliver is a meticulously calculated and verified "bridge" in the microscopic world, small yet carrying all the expectations for the stable operation of the device.
3.Battery Spring Product Features & Advantage

5.Battery Spring Product Application
Tiny Bodies, Huge Responsibilities: Miniature Battery Contacts for Cutting-Edge Applications
Implantable and Wearable Medical Electronics: Internal battery connections for pacemakers, neurostimulators, and continuous glucose monitoring patches require extremely high biocompatibility, long-term reliability, and absolute safety.
Micro-Sensors and Actuators: Energy storage unit connections in Internet of Things (IoT) sensor nodes, MEMS devices, and micro-drones require reliable electrical contact under extreme size and weight constraints.
High-End Audio Equipment: Miniature battery contacts in top-of-the-line in-ear monitors and bone conduction headphones demand extremely low contact noise and excellent resistance to sweat corrosion.
Precision Instruments and Spacecraft Subsystems: In non-repairable battery backup systems for scientific instruments and satellite modules, the contacts must withstand the severe vibrations of the launch phase and the harsh conditions of the space environment.
