⚙️ Detailed Overview

The CR2032 3V Lithium Coin Cell with Pins is designed to deliver consistent voltage output over a long period of time, ensuring reliable operation for microcontrollers, sensors, and memory modules. Its PCB-mountable pin configuration simplifies integration in circuit designs and ensures a stable mechanical and electrical connection.

Unlike regular coin cells that require holders, this version can be directly soldered to the board, saving space and improving reliability in applications where vibrations or mechanical movement could dislodge traditional holders.

The lithium chemistry inside ensures high energy density, stable discharge characteristics, and low internal resistance, which are crucial for maintaining voltage stability in timekeeping and backup power applications.

💡 Typical Applications

The CR2032 with pins is widely used across many electronic applications, including:

• Real-Time Clock (RTC) Backup Power – maintains accurate timekeeping when the main power is off.

• Microcontroller and Arduino Projects – powers low-power systems or serves as a backup for SRAM or EEPROM.

• Digital Meters and Sensors – provides a stable voltage supply to precision instruments.

• Computer Motherboards (BIOS Battery) – retains CMOS memory data during power-off conditions.

• Remote Controls and Small Devices – ensures long-lasting, dependable performance in compact electronics.

• Wearable Devices and IoT Nodes – suitable for embedded, low-power applications requiring long battery life.

⚡ Performance and Reliability

The CR2032 Coin Cell with Pins is engineered for durability and reliability. It maintains its voltage for most of its discharge cycle, providing consistent performance in sensitive electronic circuits. The solderable pin design ensures a strong connection, eliminating the need for additional battery holders or connectors that might loosen over time.

With a low self-discharge rate, the battery retains most of its charge even after years of storage, making it an excellent choice for backup or standby applications. Its wide operating temperature range also allows use in both indoor and outdoor projects without performance degradation.
