Battery contact spring is a precision metal component made of conductive elastic materials (such as stainless steel, phosphor bronze, beryllium copper, etc.). Through structural designs like spiral, wave, or sheet type, it generates continuous contact pressure via elastic deformation to achieve reliable connection between battery positive/negative electrodes and electronic device circuit contacts. It is a core component in battery-powered equipment that ensures current transmission and contact stability.

We are a professional manufacturer of high-performance battery contact springs, specially engineered to deliver reliable electrical connectivity and stable power transmission between batteries and various electronic devices. Our contact springs act as the critical conductive bridge in battery-powered products, ensuring consistent current flow and long-term operational stability for your devices.
Crafted from premium raw materials including 304/316 stainless steel, high-carbon steel and copper alloys, our battery contact springs boast excellent elasticity, high electrical conductivity and superior corrosion resistance. We offer a full range of surface treatment options such as galvanization, nickel plating, gold plating and tin plating, which effectively enhance wear resistance, anti-oxidation performance and contact conductivity, adapting to different working environments and application requirements.
With precise dimensional machining and strict quality control, our springs are perfectly matched with AAA, AA, C, D, button and other standard battery models, as well as customized non-standard battery specifications. They feature stable rebound force, no easy deformation after long-term use and tight contact with battery electrodes, effectively avoiding poor contact, power failure and other problems.
Our battery contact springs are widely applied in consumer electronics, small home appliances, power tools, toys, medical devices, smart home products, remote controls, calculators and various portable electronic devices. We fully support OEM/ODM customization services: according to your drawings, samples or technical requirements, we can customize the spring’s size, shape, material, surface treatment and elastic performance to meet the personalized matching needs of your products.
As a factory direct supplier with rich experience in spring manufacturing, we ensure high product consistency, short production lead time and favorable bulk pricing. All products undergo strict performance testing before delivery to guarantee reliable quality and long service life. We are committed to providing you with high-quality, cost-effective battery contact spring solutions and professional one-stop after-sales service.
