Product Electric Performance Test
| No. | Items | Test Conditions | Requirements |
| 1 | Capacity retention | Fully charging, store them at (20±5)℃ for 28 days, then discharge to 16.5V @0.2C.(the residual capacity is above 85% of nominal capacity) | Discharging time4.25h |
| 2 | Cycle Life @25℃ | Discharge to 16.5V @0.2C, then Charge the battery @0.2C to reach 25.2V. Then charge the battery at constant 25.2V voltage until the charging current decreasing to 0.02C. Rest for 10 min. discharge to 16.5V@ 0.2C and rest for 10 min. Continue the charge/discharge cycles until discharge capacity lower than 80% of rated capacity. | Cycles life ≥300 |
| 3 | storage | Charge the battery to 40%~65% of its rated capacity using standard charging mode, then keep it in an 20℃±5℃, humidity 45% ～ 85% room for 12 months, fully charge and discharge it @0.2C until voltage down to 16.5V. (The testing sample should be within 3 months dated from production date) | Discharge time≥4h |
