Product Description
Non-Standard Battery Contact Spring Design, Optimized Contact Force & Stroke for Specific Battery Compartment Space
1.Battery Spring Quick Detail
We are committed to being a leader in battery connection solutions for the high-end consumer electronics field. With a deep understanding of micro precision forming and electrical contact physics, we provide high-performance, high-consistency battery springs and contact strips for global brands. Our production line covers precision stamping to micro spring forming, equipped with fully automated plating and inspection units. With agile response (48-hour samples), stringent process control (based on IATF 16949), and scalable capacity (daily capacity over millions of pieces), we ensure your product has a reliable “heart” connection in the fiercely competitive market.
2.Battery Spring Product Description
An exceptional battery contact component needs to withstand stress relaxation, contact corrosion, and mechanical wear throughout the product's entire lifespan. We achieve this through a multidisciplinary approach: at the material level, we select alloys with excellent elasticity, conductivity, and stress relaxation resistance; at the design level, we optimize the curvature radius and support structure of the contact points to distribute stress and obtain a smooth force-displacement curve; at the manufacturing level, we control the forming speed and heat treatment parameters to ensure the stability of the material's microstructure; and at the surface treatment level, we precisely control the plating thickness and porosity to resist environmental corrosion. What we deliver is not just a part, but a long-term guarantee of connection reliability..
3.Battery Spring Product Features & Advantage
|
Feature |
Advantage to You |
|
Material Science-Level Selection Support |
Recommends the most suitable base material and plating combination based on your current load, operating environment, and cost target, achieving the optimal balance of performance and cost. |
|
Micron-Level Dimension & Form Control |
Using high-precision molds and optical inspection, we ensure micron-level accuracy of critical dimensions of the spring contacts (such as contact height and arch curvature), guaranteeing assembly consistency and contact reliability. |
|
Enhanced Plating for Corrosive Environments |
We offer multi-layer plating solutions (such as copper base + nickel plating) or thick gold plating options to effectively withstand harsh environments such as high humidity, sulfur-containing atmospheres, or sweat corrosion, thereby reducing the risk of failure. |
|
Integrated Manufacturing with Connectors |
Can integrate battery contact strips with plastic carriers via insert molding or assembly to form complete connector modules, providing plug-and-play solutions and simplifying your supply chain. |

5.Battery Spring Product Application
Connecting Energy, Driving Innovation: Core Application Scenarios of Battery Springs
Ultra-thin Portable Devices: Providing low-profile battery contacts for ultra-thin laptops and tablets, offering sufficient spring force and travel within limited Z-space.
Waterproof and Dustproof Devices: Used in battery compartments of sports cameras, outdoor walkie-talkies, and electric toothbrushes, where the spring contacts need to work in conjunction with sealing rings and withstand certain pressure and corrosion.
Devices with High-Frequency Battery Replacement: Such as TV remote controls, wireless mice, and toys, where the battery springs require extremely high insertion and removal life and resistance to plastic deformation to ensure good contact during long-term use.
High or Low Temperature Environment Devices: Car remote keys and outdoor monitoring equipment, where the battery connectors need to maintain stable mechanical and electrical performance across a wide temperature range (-40°C to +125°C).
