Description
Atomfair CR2032 Button Battery Holder with Sealed O-Ring & Mesh Design & Matching Accessory Series
Product Overview
Atomfair?s button battery holder is a precision-engineered component featuring a dual-function mesh structure and sealed O-ring, optimized for CR2032 batteries while maintaining compatibility with CR2016 (20mm×1.6mm) and CR2025 (20mm×2.5mm) models via a unified 20mm diameter design.
Constructed from premium 304/316 stainless steel, select variants can be customized with gold-plating or aluminum-coating finishes to meet enhanced conductivity or corrosion resistance demands. The integrated sealed O-ring delivers reliable leak-proof protection, while the breathable mesh structure ensures uncompromised gas exchange, balancing protection and functional performance. Each product is paired with a full suite of matching accessories for one-stop procurement.
Matching Accessories
To support complete button battery assembly workflows, we offer the following complementary components:
- Multi-specification button battery gaskets
- Wave springs and conical springs
- Customizable fasteners for device integration
