3.Test Conditions
3.1 Standard Test Conditions
4.1.1 All tests defined in this Product Specification are conducted at temperature 25±2℃,humidity 15%～90%RH,atmospheric pressure 86～106kPa.
4.1.2 Unless there are other special instructions,all performance was tested with unused cells within 1month after production date.
3.2 Standard Charge Method
The "Standard Charge" means in an ambient temperature of 25±2℃,the cell was discharged with 0.5C constant current to cut-off voltage 2.0V,standing 1hour.Then charged it with 0.5C constant current to 3.65V,then change into constant charge mode,until the charging current down to 0.05C,then stop charging and standing 1h.
4. Dimensions
5.Shipment
The Cell shall be shipped by insulated packaging and in voltage range of 3.300±0.030V, and 50% SOC, or in accordance with customers’ requirement.The remaining capacity before charging shall depends on the storage time and conditions.To ensure the cells in a good transport environment is necessary.
