Product Description
Custom High-Precision Battery Contact Springs for Stable Conductivity & Accurate Travel
1.Battery Spring Quick Detail
Tingfeng Hardware specializes in miniature, high-reliability battery connector springs and contacts. We focus on providing stable electrical connection solutions for various portable electronic devices. Our products range from traditional cylindrical battery contacts to miniature button cell connectors integrated into smart devices. Through precision stamping and forming processes, combined with carefully selected conductive elastic materials (such as phosphor bronze and nickel-plated steel) and advanced surface treatments (such as gold plating and tin plating), we ensure that each battery spring has extremely low contact resistance, stable contact pressure, and excellent corrosion resistance, guaranteeing long-lasting and stable power supply for your devices.
2.Battery Spring Product Description
Battery springs are the "first line of defense" in a device's power system, and their performance directly impacts whether the device can power on and operate stably over the long term. We view them not merely as mechanical springs, but as integrated electro-mechanical components. Our design takes into account electrical contact theory, including contact resistance, insertion and extraction force, vibration loosening, and fretting corrosion. We offer dual-contact designs with self-cleaning capabilities, floating structures to accommodate battery expansion, and precision packaging for SMT automatic assembly. Through close collaboration with our customers, we ensure that our battery springs achieve optimal electrical performance, mechanical lifespan, and assembly compatibility within limited space.
3.Battery Spring Product Features & Advantage
|
Feature |
Advantage to You |
|
Ultra-Low & Stable Contact Resistance |
By using highly conductive base materials and applying precious metal plating such as gold, combined with optimized contact point shape and pressure, the contact resistance is ensured to be <20mΩ with minimal long-term variation, thereby minimizing energy loss and voltage drop and improving battery utilization efficiency. |
|
Precise & Long-Lasting Contact Force |
Through precise material heat treatment and structural design, the spring provides stable and appropriate contact force throughout the battery's entire lifespan (including repeated replacements), ensuring reliable electrical conductivity while preventing excessive pressure from damaging the battery electrodes. |
|
Excellent Corrosion & Fretting Wear Resistance |
To address the potential for trace gases and frequent micro-movements in batteries, we offer special plating solutions such as thick gold and matte nickel coatings, which effectively suppress surface oxidation and fretting corrosion, maintaining a clean contact interface over the long term and preventing failures caused by corrosion. |
|
High Integration & Automation-Friendly Assembly |
Battery springs can be designed as SMT components, supplied in tape and reel packaging, or pre-soldered to FPC/PCB as modules. This greatly simplifies your production line assembly process, improves production efficiency, and reduces human error. |

5.Battery Spring Product Application
Our battery springs are the "energy switches" for portable electronic devices:
Smartphones and Tablets: Built-in rechargeable lithium battery connector springs and SIM card tray springs require ultra-thin design, high elasticity lifespan, and stable low resistance.
Smart Wearables and IoT Devices: Button cell battery holder springs in smartwatches, Bluetooth headsets, and electronic tags require miniaturization, vibration resistance, and excellent resistance to sweat corrosion.
Medical and Healthcare Devices: Battery contacts in hearing aids, blood glucose meters, and portable monitors demand high biocompatibility, long-term contact reliability, and low noise (anti-fretting corrosion).
Power Tools and Remote Controls: Internal contacts in power tool battery packs and battery compartment springs in remote controls emphasize high current carrying capacity, high insertion/extraction lifespan, and impact resistance.
