Description
Atomfair Button Battery Conical Spring and Matching Accessory Series
1. Basic Technical Parameters
The core product is a conical spring for button battery systems, with key dimensional parameters: diameter 15.4mm × height 1.2mm (custom sizes available), thickness 0.25mm, and unit weight 0.1 ounces (2.8 grams). The conical structure is precision-machined to ensure stable elastic force output, with an elastic force range of 0.5-2.0N, which can be customized according to battery model and assembly requirements.
2. Core Performance Advantages
The product integrates three core performance advantages to meet the assembly and operation needs of button batteries:
-
Precision Elastic Force Control: The elastic force fluctuation is less than ±0.05N, ensuring stable contact between the battery electrode and the current collector, avoiding poor contact caused by insufficient elastic force or excessive pressure damage to the battery structure.
-
Excellent Fatigue Resistance: It can withstand 10,000+ compression cycles without elastic failure, maintaining stable performance during long-term battery charge-discharge tests.
-
Structural Compatibility: The conical design is perfectly matched with button battery shells (CR2016, CR2025, CR2032), ensuring seamless assembly and avoiding loose fit during battery operation.
3. Matching Accessories & Model Compatibility
To cover full-scenario application needs, we provide a complete product supporting system:
-
Multi-model Compatibility: Compatible with mainstream button battery models including CR2016, CR2025, and CR2032, with matching spring specifications for each model to ensure assembly stability.
-
Full Range of Accessories: A complete set of multi-specification precision gaskets (15.8mm, 20.2mm diameter) and matching fasteners, designed to integrate seamlessly with conical springs and battery shells for diverse assembly scenarios.
-
Material Customization: Spring material options include 304 stainless steel, 316 stainless steel, and gold-plated finishes, tailored to different experimental and industrial application requirements.
