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 12V @0.2C.(the residual capacity is above 85% of nominal capacity)	Discharging time4.25h
2	Cycle Life @25℃	Discharge to 15V @0.2C, then Charge the battery @0.2C to reach 21.9V. Then charge the battery at constant 21.9V voltage until the charging current decreasing to 0.02C. Rest for 10 min. discharge to 15V@ 0.2C and rest for 10 min. Continue the charge/discharge cycles until discharge capacity lower than 80% of rated capacity.	Cycles life ≥1500
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 12V. (The testing sample should be within 3 months dated from production date)	Discharge time≥4h
