01 — About

What it does

The CR2032 3V Lithium Coin Cell is a high-performance primary lithium button battery engineered to provide stable, long-lasting backup power for motherboard BIOS/CMOS memory, Real-Time Clock (RTC) modules, microcontrollers, and precision electronic timers. With a nominal voltage of 3V and exceptional discharge stability, it guarantees that critical operational parameters and accurate clock timing are maintained uninterrupted.

Key features

  • Stable 3V nominal output voltage
  • High energy density in a compact coin cell form factor
  • Ultra-low self-discharge rate with up to 10-year shelf life
  • Leak-resistant construction for safe device operation
  • Wide operating temperature performance
  • Ideal backup power source for CMOS BIOS memory and RTC timers
  • Non-rechargeable primary lithium manganese dioxide (LiMnO2) chemistry

Good to know

  • Do not attempt to recharge, short-circuit, or disassemble this non-rechargeable lithium cell.
  • Verify correct polarity (+ and – orientation) prior to installation in battery holders or connectors.
  • Keep out of reach of children; coin cells present a serious ingestion hazard.
  • Store in a cool, dry place away from direct sunlight to preserve shelf life.
  • Dispose of depleted batteries responsibly according to local environmental guidelines.
