CR2032 3V Lithium Coin Cell Battery PCB Mount (Through-Hole Backup Battery)

The CR2032 3V Lithium Coin Cell Battery PCB Mount is a compact primary lithium battery designed with through-hole mounting pins for direct installation onto printed circuit boards. Based on Lithium Manganese Dioxide (Li-MnO₂) chemistry, it provides a stable 3V output, high energy density, and long shelf life for memory backup and low-power electronic applications. The PCB mounting configuration eliminates the need for a separate battery holder, making it ideal for embedded systems, industrial electronics, RTC backup, CMOS memory, and custom PCB designs.

Its reliable performance and low self-discharge characteristics make it an excellent choice for long-term backup power in electronic circuits.
