Temperature Dependence of Capacity (Discharge)
Cells shall meet the discharge capacity requirements listed in the below table under respective discharge temperatures. The capacities are to be measured with constant discharge current 300mA (2.75V cut-off) after standard charge at 25±2°C.
Discharge Temperature | -20°C | 25°C | 60°C |
Discharge Capacity | 50% | 100% | 90% |
Cycle Life
30min rest period after standard charge, 0.2CmA discharge to a cut-off voltage of 2.75V, 30min rest period, the capacity shall be measured after 300 cycles of standard charge and discharge at 25±2°C.
Capacity ≥ 228mAh
Charge Retention
Item | Measuring Procedure | Requirements | |
Storage Characteristics 1
| 1 | The capacity on 0.5CmA discharge shall be measured after standard charge and then storage at 25±2°C for 30 days. | Remaining Capacity ≥85% |
Storage Characteristics 2 | 1 | The capacity on 0.5CmA discharge shall be measured after standard charge and then storage at 60±2°C for 7 days. | Remaining Capacity ≥60% |
2 | After above measured Remaining capacity, the capacity on standard discharge shall be measured after standard charge. | Recovery capacity ≥80% | |
