GP Batteries LITHIUM BUTTON CELL CR1632

The CR1632 is a compact, high‑performance lithium button cell designed for devices that demand reliable power in a small footprint. Manufactured by GP Batteries, this single‑use battery delivers a stable 3 V output and a capacity of approximately 140 mAh, making it ideal for a wide range of electronic applications.

Key Technical Specifications

• Form Factor: Button/coin cell
• Diameter: 16.0 mm (standard CR1632 size)
• Thickness: 3.2 mm
• Nominal Voltage: 3 V
• Capacity: 140 mAh (typical)
• Manufacturer: GP Batteries
• Reference Code: 8.3.031

Performance Characteristics

The CR1632’s lithium chemistry provides a low self‑discharge rate, ensuring that the battery retains its charge for extended periods when not in use. Its high energy density allows it to power small devices such as:

• Digital watches and chronographs
• Fitness trackers and health monitors
• Keyless entry systems and remote controls
• Medical devices like hearing aids and glucose meters
• Small electronic gadgets, including calculators and handheld game consoles

Because the cell maintains a consistent voltage output throughout its life cycle, it eliminates the need for complex power management circuitry in many low‑power applications.

Installation and Compatibility

The CR1632 is designed to fit standard 16 mm × 3.2 mm battery compartments found in most consumer electronics. When installing, ensure that:

• The positive (+) side of the battery aligns with the marked terminal on the device.
• All contacts are clean and free from corrosion or debris.
• A new cell is inserted only when the previous one has reached the end of its useful life to avoid damage to sensitive electronics.

GP Batteries provides a blister pack containing a single CR1632, making it convenient for quick replacements in field service or DIY projects.

Reliability and Longevity

Thanks to its lithium core, the CR1632 offers:

• A long shelf life of up to 10 years when stored at room temperature.
• Stable performance across a wide temperature range (typically –20 °C to +60 °C).
• Minimal voltage sag under load, which is critical for devices that require precise timing or signal integrity.

These attributes make the CR1632 a trusted choice for mission‑critical applications where battery failure could lead to significant downtime or safety concerns.

Environmental Considerations

While lithium button cells are highly efficient, they contain materials that should be handled responsibly. GP Batteries encourages proper recycling of spent CR1632 units through local electronic waste programs to minimize environmental impact and recover valuable metals.

Conclusion

The GP Batteries LITHIUM BUTTON CELL CR1632 combines compact size, reliable voltage output, and long shelf life into a single‑use solution that meets the demands of modern low‑power electronics. Whether powering a smartwatch, a medical sensor, or any other device that relies on steady 3 V power, this battery delivers consistent performance with minimal maintenance.

For professionals and hobbyists alike, the CR1632 remains an essential component in the toolkit for designing, repairing, and maintaining small electronic systems.
