When device design demands a slim profile but power requirements refuse to compromise, traditional batteries fall short. Enter the CR3032 3V Lithium Manganese Dioxide (Li-MnO2) Battery—the ultimate solution for engineers who need high capacity in a low-profile form factor.

Characterized by its unique, ultra-wide 30mm diameter, the CR3032 spreads its internal chemistry across a broader surface area. The result? A massive 500mAh capacity packed into a remarkably thin 3.2mm casing. It is the definitive, long-lasting power source for slim-line POS systems, tight industrial control panels, and innovative smart electronics.

Why Specify Our CR3032? Engineered for Slim-Line Endurance

1. Broad Footprint, Massive Capacity (500mAh)

Space constraints are the enemy of battery life. By utilizing a wider 30mm diameter, this cell achieves a robust 500mAh capacity without increasing device thickness. It offers the perfect golden ratio of ultra-thin design and extended operational life, dramatically reducing maintenance intervals.

2. Unwavering Thermal Stability (-20°C to 70°C)

Industrial and commercial devices do not live in perfectly climate-controlled environments. Formulated with advanced lithium chemistry, our CR3032 guarantees stable, continuous voltage discharge through freezing warehouses and sweltering automated factory floors, reliably operating from -20°C to 70°C.

3. The “Store & Forget” Advantage (<2% Annual Self-Discharge)

Inventory aging should not mean capacity loss. Thanks to high-purity internal components and a precision-engineered outer seal, the CR3032 boasts an ultra-low self-discharge rate of less than 2% per year. You can stock up your supply chain knowing these batteries will perform like new years after purchase.

4. Exacting Dimensional Precision (Φ30.0 × 3.2mm)

Manufactured to flawless global tolerances, this wide-format cell ensures perfect contact in standard CR3032 PCB surface-mounts and battery holders. Its expansive surface area also provides excellent electrical contact, preventing micro-disconnects in high-vibration industrial settings.
