Warnings & Precautions
- Charge Within Specifications: Do not charge above the maximum voltage of 3.65V or exceed the maximum continuous charge current specified for the battery .
- Temperature Monitoring: Charge only between 0°C to 45°C. Never charge a battery that is below freezing (0°C) or feels hot to the touch.
- Avoid Over-Discharge: Stop using the battery before reaching the cut-off voltage (2.0V - 2.5V).
- Respect Current Limits: Do not exceed the maximum continuous discharge current for prolonged periods.
- Temperature Management: Avoid discharging outside the recommended temperature range (-20°C to 60°C).
- Partial Charge Storage: For long-term storage (longer than one month), store the battery at a 30%-50% State of Charge (SOC). This minimizes age-related degradation.
- Cool and Dry Environment: Store in a cool, dry place away from direct sunlight, moisture, and heat sources. Ideal storage temperature is between -20°C to 25°C.
