Design and Construction

The CR1632’s compact form factor—just over one centimeter in diameter and a little more than three millimeters thick—makes it perfect for small devices such as key fobs, remote controls, medical monitors, and various consumer electronics. The robust lithium chemistry ensures minimal self‑discharge and maintains voltage stability even under high drain conditions.

Each battery is sealed within a clear blister that protects the cell from physical damage while allowing quick visual inspection of its condition. The blister dimensions (56 mm × 65 mm) are designed to fit standard packaging trays, facilitating efficient storage and handling in manufacturing or retail environments.

Performance Characteristics

The 140 mAh capacity provides a balance between size and endurance, enabling devices that require moderate power for extended periods. Lithium chemistry delivers a flat discharge curve, meaning the voltage remains close to 3 V throughout most of its life cycle, which is critical for sensitive electronics.

Because it is a single‑use battery, the CR1632 offers predictable performance without the risk of recharge cycles affecting longevity or safety. This makes it suitable for applications where replacement rather than recharging is preferred, such as in medical devices or high‑reliability industrial controls.

Applications and Use Cases

• Key Fobs & Remote Controls: The small size and stable voltage make the CR1632 a popular choice for vehicle key fobs, garage door openers, and wireless remote systems.
• Medical Devices: Portable health monitors, blood pressure cuffs, and other medical instruments benefit from the battery’s low self‑discharge and reliable output.
• Consumer Electronics: Digital thermometers, small handheld gadgets, and electronic toys often use CR1632 cells for their compact power needs.
• Industrial Sensors: Low‑power sensors in automation systems can rely on the CR1632’s consistent voltage to maintain accurate readings over long periods.

Safety and Handling

The lithium chemistry of the CR1632 is designed with safety in mind. The battery is sealed, preventing leakage or exposure to moisture. However, it should be stored away from extreme temperatures and kept out of reach of children to avoid accidental ingestion.

When disposing of used batteries, follow local regulations for hazardous waste. Recycling programs often accept lithium button cells, ensuring that valuable materials are recovered responsibly.

Compatibility and Interchangeability

The CR1632’s dimensions (16 mm × 3.2 mm) match the standard size for many devices originally designed for this type of cell. It is interchangeable with other 3 V lithium button cells that share these physical specifications, though it is always recommended to verify device compatibility before replacement.

Manufacturing and Quality Assurance

Produced by VARTA, a well‑known name in battery technology, the CR1632 undergoes rigorous quality control. Each unit is tested for voltage output, capacity, and physical integrity before being sealed in its blister. This ensures that every battery delivered to the customer meets the high standards expected of VARTA products.

Conclusion

The VARTA CR1632 Lithium Button Cell Battery offers a reliable, compact power solution for a wide range of electronic devices. With its 3 V output, 140 mAh capacity, and secure blister packaging, it delivers consistent performance while maintaining safety and ease of use. Whether you need a replacement for a key fob or a dependable power source for a medical device, the CR1632 stands out as a trusted choice in the button cell market.
