- Hermetic Sealing
- Compliant with IEC86-4 safety standard
Typical Discharge Curves at 23℃±2℃ (Mid-Discharge Values)
Excellent Low-Current Discharge Stability: Under a 5mA micro-current discharge condition (green line), the battery exhibits an extremely stable and long-lasting operating voltage plateau, steadily maintaining between 2.9V and 3.0V for the vast majority of the discharge cycle. Under this condition, the battery fully releases its 1600mAh nominal capacity, indicating it is highly suitable for long-term, low-power standby or operating devices.
Noticeable Load Sensitivity (Polarization Effect): The actual usable capacity and operating voltage plateau are highly sensitive to the magnitude of the discharge current. As the load current increases from 5mA to 100mA (blue line), due to internal polarization effects and internal resistance voltage drop, the overall voltage plateau shifts down to approximately 2.7V. Furthermore, the effective released capacity upon reaching the 2.0V cut-off voltage shrinks to roughly 1200mAh.
Limited High-Current Continuous Discharge Capability: When the continuous discharge current surges to 500mA (red line), the operating voltage drops rapidly to around 2.5V. Under this higher load, the battery’s discharge curve bottoms out relatively quickly, yielding only about 480mAh of capacity (less than one-third of its nominal capacity) when the 2.0V cut-off is reached.
