CP521728 3V Disposable Lithium Manganese Soft Pack Battery: Slim and Elongated Design, Unlocking New Possibilities for Linear Space Power Supply

When a product’s internal space features a unique strip or narrow slot layout, conventional batteries are often difficult to fit. The CP521728 3V disposable lithium manganese soft pack battery is specifically designed for such scenarios. Its unique ultra-thin, elongated shape of 5.2×16.5×28.5mm can be perfectly embedded in pen-shaped devices, smart card slots, or edge modules, providing a durable, stable, and safe power solution for space-constrained linear layouts.

Linear Fit, the Art of Space Utilization

The CP521728 breaks through the limitations of traditional battery shapes. Its aspect ratio is precisely calculated to seamlessly fit the edge of a PCB board or fill narrow cavities. This design allows product engineers to achieve perfect integration of power and structure in strip-shaped devices such as electronic pens, smart door cards, and miniature sensors, freeing up more core space for other components.

Thin but Powerful, a Core of Long-Lasting Power
Thanks to the inherent advantages of the lithium manganese (Li-MnO2) chemical system, the CP521728 still boasts excellent performance despite its slim profile:

• High volumetric energy density: Maximizes energy storage in an ultra-thin form factor, ensuring long-lasting device operation.

• Stable discharge platform: Provides a stable 3V voltage throughout the entire service life, ensuring accurate operation of precision circuits.

• Excellent storage characteristics: Extremely low annual self-discharge rate, supporting over 10 years of effective storage and standby, meeting the long life cycle requirements of disposable devices.

• Wide temperature operating range: Adapts to ambient temperatures from -20℃ to +60℃, reliably handling various application scenarios
