Description

Atomfair Gold-plated 304 Stainless Steel CR2032 Button Battery Box (With O-ring)

Product Overview

This premium battery box is precision-engineered for CR2032 button batteries, featuring standard dimensions of 20mm (diameter) × 3.2mm (thickness) and a lightweight design of just 0.12 ounces per unit. Its compact structure fully complies with universal button battery packaging size standards, ensuring seamless integration with terminal devices and assembly lines.

Material & Process Advantages

1. Dual-layer Performance Optimization
   The shell is crafted from high-quality 304 stainless steel, with an inner gold-plated finish that delivers two core benefits:
   – Enhanced Corrosion Resistance: Forms a protective barrier against electrochemical oxidation and chemical erosion, suitable for long-term use in humid or corrosive environments.
   – Stable Electrical Conductivity: Reduces contact resistance between the battery and the box, ensuring consistent power transmission and stable device operation.
2. Superior Sealing & Leak-proof Performance
   When paired with polypropylene (PP) gaskets, the product achieves excellent sealing effects, effectively preventing electrolyte leakage and external dust intrusion, and extending the service life of packaged batteries.

Compatibility & Supporting System

1. Broad Model Compatibility
   Beyond CR2032, the battery box is fully compatible with mainstream button battery models including CR2016, CR2025, and CR2450, providing a unified packaging solution for multi-model application scenarios.
2. Customization Options
   Supports material customization with alternatives including 316 stainless steel, aluminum coating, and Kapton finishes, tailored to meet specific high-temperature resistance, conductivity, or testing requirements for mid-to-high-end applications.
3. Complete Accessory Portfolio
   Offers one-stop procurement of matching components, including multi-specification stainless steel/pure aluminum gaskets, precision wave springs, and conical springs, all designed to ensure stable assembly and electrical contact for diverse industrial and research needs.
