When hardware engineering demands massive energy reserves but vertical space is strictly limited, standard coin cells fall short. Introducing the CR3832 3V Lithium Manganese Dioxide (Li-MnO2) Battery—the ultimate wide-format power solution designed to break design bottlenecks.

By expanding the horizontal footprint to a unique 38mm diameter, the CR3832 spreads its high-purity lithium chemistry over a larger surface area. The result is an extraordinary 850mAh capacity packed into an ultra-thin, 3.2mm profile. It is the definitive power choice for slim industrial control motherboards, next-gen smart terminals, and precision electronic equipment.

Why Specify Our CR3832? The Power of Wide-Format Engineering

Unmatched 850mAh Capacity in a Slim Shell

Vertical space is often the tightest constraint on a PCB. The CR3832 offers a “Golden Ratio” for industrial designers: it delivers nearly four times the capacity of a standard CR2032 while maintaining the exact same 3.2mm thickness. This translates directly to years of uninterrupted device uptime and drastically reduced field maintenance costs.

Rugged Climate Resilience (-20°C to 70°C)

Industrial hardware rarely lives in a perfect climate. Formulated with advanced thermal stability, our CR3832 maintains a stable, reliable voltage discharge curve whether deployed in a sub-zero automated logistics hub or embedded near high-heat machinery components.

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

Supply chain predictability requires long-lasting components. Thanks to our advanced internal sealing technology and ultra-pure chemical formulation, this battery experiences an incredibly low self-discharge rate of less than 2% per year. Stock your inventory with absolute confidence.

Flawless Dimensional Precision (Φ38.0 × 3.2mm)

Manufactured under strict international quality controls, our CR3832 ensures a millimeter-perfect fit. The wide surface area provides expansive electrical contact, making the battery exceptionally stable and resistant to micro-disconnects caused by heavy industrial vibrations.
