Cell Lab Stainless Steel AG3 Coin Cell Cases [304SS Micro Battery Housings & Coin Cell Enclosures, 100 pcs]

High-precision miniature coin cell housings for medical and micro battery R&D applications

The Cell Lab Stainless Steel AG3 Coin Cell Cases are precision-fabricated micro battery housings designed for miniature energy devices such as hearing aids, sensors, and medical research batteries. Constructed from corrosion-resistant 304 stainless steel, each case set includes both the anode and cathode caps, along with a polypropylene (PP) sealing gasket for reliable insulation and leak protection.

With standard AG3 dimensions of Ø7.9 mm × 3.6 mm, these housings are widely used in micro battery development, electrode testing, and prototype fabrication, ensuring stable electrochemical performance under laboratory and pilot-scale conditions.

Key Features

  • High-Purity 304SS Construction – Excellent corrosion resistance compatible with most battery electrolytes.

  • Complete Cell Set – Includes both anode and cathode shells plus a PP sealing gasket for secure assembly.

  • Micro Battery Compatible – Ideal for AG3-size cells used in hearing aids and compact power systems.

  • Precision-Machined Interior – Ensures clean surfaces and stable contact for high-purity electrode testing.

  • Research & Medical Applications – Perfect for micro battery R&D, biosensor power systems, and device prototyping.
