Fanso Button Bobbin Li-MnO2 Batteries CR2320 3V for electronics

Product catalog summary

Specification Overview

The document provides technical specifications for the CR2320 3.0V battery, focusing on its discharge characteristics under various conditions.

Discharge Characteristics at 25℃

The battery's discharge performance is detailed at a standard temperature of 25℃. The discharge curve illustrates how the battery voltage changes over time when subjected to a 15kΩ load. This data is critical for understanding the battery's expected lifespan and performance under typical operating conditions.

Discharge Curves at Different Temperatures

Discharge curves are presented for three temperatures: 0℃, 23℃, and 60℃, all under a 15kΩ load. These curves demonstrate the impact of temperature on battery performance, showing variations in discharge duration and voltage stability. Higher temperatures generally improve discharge duration, while lower temperatures reduce it.

Discharge Curves at Different Loads

Additional discharge curves compare performance under two different loads: 1.5kΩ and 15kΩ, both at 23℃. This comparison highlights how increased load (lower resistance) affects the battery's discharge time and voltage profile, with heavier loads leading to faster voltage drop and shorter battery life.

Certification

The battery is UL component recognized, with the file number MH46165, indicating compliance with safety and quality standards.

Key Points and Recommendations

Operating temperature significantly affects battery discharge duration; optimal performance is near room temperature (23℃).
Higher load currents (lower resistance) reduce battery life and voltage stability.
Design considerations should account for temperature and load to optimize battery usage.
UL recognition ensures the battery meets established safety standards.
