Coin cell battery Duracell CR2032 3V lithium — pack of 4

Duracell CR2032 is a 3V lithium coin cell battery supplied in a pack of 4. Designed for small electronic devices such as watches, key fobs, calculators, fitness trackers and motherboards, it provides a stable output voltage and a long shelf life. The compact, lightweight design makes these batteries easy to store as spares or to install in devices where size and reliability are critical.

Advantages

Duracell CR2032 batteries deliver consistent 3V power suitable for low- to moderate-drain electronics. The lithium chemistry ensures low self-discharge for extended storage life and resistance to performance loss in variable temperatures. The coin cell format provides a high energy density relative to size, enabling reliable operation in thin devices. Supplied as a pack of four, these batteries offer value for replacement or backup needs.

How to use

When replacing a battery, power off the device if possible and open the battery compartment following the device manufacturer’s instructions. Note the polarity marking in the compartment and install the CR2032 cell with the positive (+) side facing the indicated direction. Ensure the cell is seated correctly and the compartment is closed securely. Dispose of used lithium coin cells in accordance with local regulations or take them to a battery recycling point.

Usage recommendations

Store unused batteries at room temperature in their original packaging until needed and avoid direct sunlight or high humidity. Replace all batteries of the same device at the same time to maintain consistent performance, and verify device functionality after installation. Keep coin cells out of reach of children and seek immediate medical attention if a cell is swallowed.
