High-Conductivity Battery Contact Spring | Custom Sizes Available | Corrosion-Resistant | Stable Elastic Force for Long-Term Use

Product Description:

Our Battery Contact Springs are precision-engineered for reliable electrical conductivity, stable mechanical performance, and long-term durability. Designed to maintain consistent contact pressure and low resistance, they are ideal for battery compartments in a wide range of applications such as consumer electronics, automotive devices, medical equipment, and industrial instruments.

Manufactured from high-quality materials such as phosphor bronze, stainless steel (SUS301/304), and beryllium copper, the springs can be customized in shape, size, and plating—nickel, tin, or gold—to suit your application’s environmental and conductivity requirements.

We offer both compression and leaf spring designs, supporting surface mount, snap-in, soldering, or insert-molding installation methods. Each spring is produced using high-precision stamping or CNC forming, with optional heat treatment and passivation for enhanced performance.

Whether you need a standard battery contact or a fully customized spring with tight tolerances and specific load-force characteristics, we provide full support from prototyping to volume production, including CAD modeling, rapid sampling, and quality assurance.
