CR2032 3V Lithium Coin Cell Battery

Compact 3V Power for Low-Power Electronics

The CR2032 3V Lithium Coin Cell Battery is a compact, non-rechargeable power source designed for compatible low-power electronic devices and circuits.

With its standard approximately 20mm diameter and 3.2mm thickness, the CR2032 is widely used in electronics that require a compact and portable 3V power source.

It is particularly useful for Real-Time Clock (RTC) backup circuits, memory retention, small sensors, compact embedded projects, remote controls, calculators, and other compatible low-power electronic devices.

The small size makes it easy to integrate into projects where space is limited. When used with a compatible CR2032 battery holder or socket, the battery can be easily installed and replaced when required.

For students and electronics learners, the CR2032 is also an excellent introduction to battery-powered circuits, polarity, voltage, energy storage, and low-power embedded system design.

Whether you are building a compact electronics prototype, powering a compatible backup circuit, or preparing components for STEM laboratory activities, this standard-size lithium coin cell provides a convenient portable power source for appropriate applications.
