1) Charging time is based on one complete charge from the 0~100% SOC. Contact and discuss with LG Energy Solution if trickle charging is required to maintain fully charged state (ex. Trickle or floating charge).
2) The maximum continuous charge or discharge current herein is the allowable current to operate cell without possibility of dramatic degradation of the cell. (Max. cell surface temperature should be controlled by BMU protection unit below 55℃ for charging and 70℃ for discharging). “Complete full charge” means that cell is charged from the minimum discharge voltage (refer to 2.8) to the max charge voltage (refer to 2.5) without stopping for 1 cycle. The charge and discharge current herein is the maximum allowable value in which the battery cell can perform normal charge/discharge without sudden internal changes such as CID activation. But this has nothing to do with guarantee of cycle performance and/or single cell degradation speed. For detailed Criteria for Cell basic properties (such as cycle life and capacity, etc), please refer to the explicit current conditions in each sections of this document.
3) The operating temperature range defined in this section (2.13) is the maximum allowable range in which the battery cell can perform normal charge/discharge without sudden internal changes such as CID activation. However, even if the cell is charged / discharged within the above (2.13) operating temperature range, characteristics of the cell such as capacity / voltage / internal resistance may be deteriorated depending on factors such as the accumulated number of charge / discharge cycles, usage time and diverse charge/discharge current profiles. For detailed Criteria for Cell basic properties (such as cycle life and capacity, etc), please refer to the explicit temperature conditions in each sections of this document.
4) The storage temperature and period range defined in this section (2.14 and 2.15) is the maximum allowable range in which the battery cell can perform normal charge/discharge without sudden internal changes such as CID activation. However, even if the cell storage (including the cell storage after assembled inside the final application in the field) is within the above (2.14 and 2.15) temperature and range, characteristics of the cell such as capacity / voltage / internal resistance may be deteriorated when compared to the fresh cell state (ex-factory state). It is highly recommended that the cell should be stored (including the cell storage after assembled inside the final application in the field) in the room temperature (25℃) and under the shipping SOC. For detailed Criteria for Cell basic properties (such as cycle life and capacity, etc), please refer to the explicit temperature conditions in each sections of this document.
5) Recovery Capacity: After storage, cells shall be discharged with Std. discharge condition per 4.1.2, and then cells shall be charged with Std. charge condition per 4.1.1, and then discharged with Std. discharge condition per 4.1.2.
