Discharge charateristics at 25℃ Test
The provided chart details the battery’s discharge performance at 25°C, comparing operating voltage (V) and capacity (mAh) across 1mA, 10mA, and 120mA discharge rates. The data highlights a direct inverse relationship between the discharge current and both the voltage plateau and total usable capacity. Under a light 1mA draw, the battery delivers up to 450mAh. However, a heavier 120mA load noticeably suppresses the operating voltage and effectively halves the usable capacity to 225mAh prior to hitting the 1.8V cut-off.
Voltage VS Current & Temperature Curve
This graph illustrates the battery’s operating voltage response to varying discharge currents across three distinct ambient temperatures (20°C, 0°C, and -20°C). Plotted with a logarithmic scale for the continuous current (mA), the curves demonstrate that the operating voltage naturally declines as the load increases, primarily due to internal resistance. Furthermore, ambient temperature plays a critical role in voltage stability. At 20°C, the battery maintains a strong, elevated voltage profile even at higher discharge rates. In contrast, sub-zero temperatures (-20°C) significantly depress the operating voltage across all loads and limit the cell’s ability to sustain heavier currents without experiencing a rapid voltage drop.
Concise Summary (Direct and impactful)
The provided chart details how ambient temperature and discharge rate impact the battery’s usable capacity. By mapping performance at -20°C, 20°C, and 60°C, the data reveals that optimal capacity retention occurs at higher temperatures, with the 60°C curve showing the greatest resilience under load. Conversely, operating at -20°C causes a severe suppression of available capacity, with a rapid decline occurring as the discharge current exceeds 10 mA. Overall, it highlights the necessary capacity trade-offs when designing applications for high-drain or low-temperature environments.
Standard Descriptive Paragraph (Best for standard datasheets)
This graph illustrates the long-term storage characteristics and capacity retention of the CP502025 pouch battery. It compares the discharge profiles of fresh cells against those stored for 5 years at room temperature, both tested under a constant 1mA discharge current at 23°C ± 2°C. The curves demonstrate that even after 5 years of storage, the battery maintains a highly stable voltage plateau. While there is a slight expected drop in the operating voltage and a minor reduction in total discharge time before reaching the 1.8V cut-off, the data highlights the cell’s excellent long-term reliability and remarkably low self-discharge rate.
Flexible order quantity to support prototype testing and mass production.
Provides a consistent 3V output during discharge.
Supports thousands of charge cycles.
Non-toxic, non-leak, stable Li-MnO₂ chemistry ensures reliable operation.
