Button battery GP CR1632 3V Lithium — single cell (CR1632)

GP CR1632 is a 3V lithium button cell supplied as a single cell, designed for small electronic devices that require a stable low-current power source. Its compact diameter and low profile make it suitable for applications where space is limited while offering long shelf life and steady output voltage for consistent device operation.

Advantages

The GP CR1632 provides a stable 3V output and low self-discharge, ensuring reliable performance over extended storage and intermittent use. Its compact round form factor is compatible with many coin-cell holders, and the lithium chemistry delivers a higher energy density compared with alkaline button cells. The single-cell packaging simplifies replacement and spare stocking for individual devices.

Suitable for

• Wrist watches and small timers
• Calculator and small electronic toys
• Car key fobs and remote controls
• Medical devices with low current draw (e.g., glucose meters, thermometers)
• Backup memory and RTC modules in electronic equipment

Key specifications

• Nominal voltage: 3 V
• Chemistry: Lithium manganese dioxide (LiMnO2)
• Cell type: Button/coin cell
• Typical dimensions: 16 mm diameter × 3.2 mm thickness
• Packaging: Single cell
• Storage characteristics: Low self-discharge, long shelf life

How to use

Install the cell into the device’s coin-cell holder observing the correct polarity: the positive side (+) faces outward according to most device markings. Ensure the contacts and holder are clean and free of corrosion before insertion. If installing into a sealed compartment, follow the device manufacturer’s instructions to avoid damage. Dispose of the used battery in accordance with local regulations for lithium batteries or take it to a designated recycling point.

Usage recommendations

Store the GP CR1632 at room temperature in a dry place away from direct sunlight and metal objects. Replace the cell when device performance indicates low voltage, and avoid short-circuiting or exposing the battery to heat or flames. For devices with critical medical functions, follow the device maker’s replacement schedule and test after installation to confirm correct operation.
