The CR2330 3V lithium coin cell battery is engineered for long-lasting performance in compact devices that require consistent voltage output over extended periods. Utilizing lithium manganese dioxide (Li-MnO₂) chemistry, it delivers a nominal voltage of 3.0V with a stable discharge curve, ensuring dependable operation until near depletion. With a typical capacity of around 265mAh and a low self-discharge rate of ≤1% per year, the CR2330 retains stored energy for years, making it perfect for devices that are used intermittently or require backup power.

This cell operates reliably in temperatures ranging from -30°C to +85°C, making it suitable for both indoor and outdoor electronics. Common applications include medical monitoring equipment, digital thermometers, automotive remote keys, watches, calculators, IoT devices, and RTC (real-time clock) backup.

The CR2330’s 23mm diameter and slim 3.0mm profile allow it to fit into space-limited designs while still offering higher capacity compared to smaller coin cells. It is a non-rechargeable primary battery with high charge/discharge efficiency, no need for a protection circuit, and minimal voltage ripple.
