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 8.4V @0.2C.(the residual capacity is above 85% of nominal capacity) | Discharging time4.25h |
2 | Cycle Life @25℃ | Discharge to 8.4V @0.2C, then Charge the battery @0.2C to reach
8.4V. Then charge the battery at constant 12.6V voltage until the
charging current decreasing to 0.02C. Rest for 10 min. discharge to 8.4V@ 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 8.4V. (The testing sample should be within 3 months dated from production
date) | Discharge time≥4h |
Mechanical Performance
No. | content | Testing method | Requirements |
1 | Vibration Test | After standard charging, put battery on the vibration table. 30 min
experiment from X, Y, Z axis. Scan rate: 1oct/min; Frequency 10-
30Hz, Swing 0.38mm; Frequency 30-55Hz, Swing 0.19mm. | No influence to batteries' electrical performance and appearance. |
2 | Drop Test | Random drop the battery from 1.0m height onto wood board 6 times. | No explosion or fire |
