Battery Springs

Battery Springs

Battery contacts, also known as battery springs or terminals, are high-precision conductive components engineered for seamless integration within battery compartments. Unlike standard industrial springs focused solely on mechanical force, battery contacts are dual-purpose components optimized to balance mechanical compression with superior electrical conductivity. Their primary function is to exert continuous elastic pressure, ensuring low-resistance and stable electrical contact between the battery terminals and the PCB, even under conditions of high vibration, impact, or prolonged usage.

Core Solutions

  • Tapered Springs: Space-saving design that collapses into a single wire height for maximum compartment efficiency.
  • Integrated Dual Contacts: Simplified series-connection for AA/AAA batteries, reducing assembly time and costs.
  • Stamped Leaf Contacts: Ultra-slim profiles for smartwatches, medical sensors, and compact IoT devices.

Performance Highlights

  • Superior Conductivity: Available in Gold, Silver, or Nickel plating to minimize signal loss and corrosion.
  • Stability: High-fatigue materials maintain constant pressure over the lifetime of the device.
  • Precision: Tight tolerances for seamless PCB and housing fitment.

Applications

Smart Home | Medical Devices | Consumer Electronics | Industrial Handhelds

In spring engineering, battery contacts demand highly deliberate material curation because they must simultaneously resolve elastic fatigue resistance and contact resistance. Raw steel has a very high electrical resistivity; without surface optimization, it causes voltage drops, heat generation, and power efficiency losses.
