III.Notes
Warning for using the Lithium ion rechargeable cell, mishandling of the cell may cause heat, fire and deterioration in performance. Be sure to read the following terms carefully
|
Precautions |
| When using a device equipped with a battery, refer to the user manual before use |
| Check the orientation of the cathode and anode terminals before packaging |
| The terminal or wire is connected to the cell module,pay attention to the insulation to prevent short circuit |
| Store the cell in a cool dry place (≤35°C,30%~50%SOC, charge and discharge once every 3 months) when not in use for a long time |
| Do not place the cell in direct sunlight or heat source to prevent high temperature of the cel |
| Do not wear metal accessories (such as rings, watches, accessories, etc.) when handling cell units |
| Do not place the cell outside the operating temperature range specified in this document |
