CR2032 3V Lithium Coin Cell Battery
The CR2032 3V Lithium Coin Cell Battery is one of the most widely used lithium button cell batteries in modern electronic devices. Designed to provide a stable 3V DC output, this compact battery delivers dependable power for low-current applications requiring long operating life and consistent performance.
Manufactured using Lithium Manganese Dioxide (Li-MnO₂) chemistry, the CR2032 combines high energy density with low self-discharge, allowing it to retain its charge for years when stored properly. With a typical capacity ranging from 220mAh to 240mAh, it is well suited for devices that require continuous backup power or intermittent operation.
Measuring 20mm in diameter and 3.2mm in thickness, the CR2032 features a compact coin-cell design that fits a wide variety of battery holders and electronic products. Its lightweight construction and standardized dimensions make it a popular choice for both consumer electronics and industrial applications.
The CR2032 is extensively used as a backup power source for Real-Time Clock (RTC) modules, CMOS memory, and computer motherboards, ensuring that time, date, and BIOS settings are retained even when the main power supply is disconnected. It is also commonly found in wireless sensors, key fobs, medical devices, calculators, digital thermometers, remote controls, wearable electronics, and IoT devices.
Its stable voltage output helps ensure reliable operation of sensitive electronic circuits, while its long shelf life minimizes maintenance and replacement frequency. The battery is also designed to operate across a wide temperature range, making it suitable for both indoor and outdoor electronic applications.
Whether you’re replacing an existing battery or powering a new electronics project, the CR2032 Lithium Coin Cell Battery offers reliable performance, long service life, and compatibility with countless electronic devices and embedded systems.
