​Q&A:

1. ​Q: What is the typical charging time for this battery cell?​​
   ​A:​​ Charging time depends on the current of the charger used. For example, using a 2A charger would take approximately 10+ hours; using a charger with a higher current would reduce the time accordingly. Please follow the device manufacturer's charging guidelines.

2. ​Q: What is the operating and storage temperature range for the cell?​​
   ​A:​​ This product offers good temperature adaptability. However, for optimal performance and lifespan, it is recommended to charge between 0°C and 45°C, and discharge between -20°C and 60°C. For long-term storage, keep in a dry environment at room temperature.

3. ​Q: Does the battery's weight (approx. 460g) significantly impact portable device design?​​
   ​A:​​ We have achieved an optimal balance between high capacity and weight. The 460g weight is quite reasonable for its 21AH capacity, offering high energy density. The impact on the overall weight of most portable devices is manageable.
