Electrical Characteristic for power tool rechargeable Li-ion battery supplier

NO.	Item	Standard	Test Method
1	Discharge rate capabilities	0.2C≥2950mAh0.5C≥2900mAh1.0C≥2850mAh3.0C≥2800mAh5.0C≥2700mAh	Standard charged, then rest for 30mins and discharge at 0.2C、1C、3C、5 C and 2.5V cut-off
2	capacity retention and recovery	Residual capacity≥94％ Recoverablecapacity≥*98％	Standard charged under the condition of normal atmospheric pressure and the environmental temperature of 23℃±3℃， Stored for 28 days, then discharge at 0.2 C to 2.75V measuring residual capacity; Then standard charge/discharge measure recoverable capacity.
3	Low TemperaturePerformance	discharge capacity≥85% rated capacityno distortion and no rupture	The cell shall be charged in accordance with the standard charge. Then stored in the temperature of -10℃±1℃ for4h, Discharge at the constant current of 0.2C down to the end-of-discharge voltage 2.750V.
4	Cycle Life		1C charged the cell to 4.2V, then change to charge with constant voltage till the current less than or equal to 0.04C, rest for 30mins; 10A discharge to 2.75V, one cycle is finished, rest for 30mins. Then repeat above steps, when capacity is less than 70% of initial capacity, the battery life is over.

Safety Characteristic of car 18650 battery

NO.	Item	Standard	Test Method
1	Overcharge	No fire、No explosion	After standard charge, rest for 10mins; then charge at constant current of 3C to 10V.(or charge at 3C for90mins).
2	Forced discharge	No fire、No explosion	The battery to be discharged with standard discharging condition, Inverse charge current =1C；time: ≥90mins
3	Short Circuit test	No fireNo explosion	The battery to be fully charged with standard charging condition, and short the positive and negative terminals with wire resistance ≤50mΩ.Tests are to be conducted at 23℃±3℃ and at 55℃ ±5℃, keep 24h or casetemperature decline to 20% of the max temperature ,test is over.
4	Crush test	No fire/No explosion	A battery is crushed between two flat surfaces. The applied force is 13 kN±1kN by hydrocylinder, Once the maximum pressure has been obtained or voltage decrease to 1/3 of nominal voltage sharply, then release pressure.
5	Shock test	No fire/No explosion	The full charged battery is fixed on shock table, to force a certain shock to three mutual vertical direction, in initial3ms, the min. average acceleration is 75gn,the peak acceleration is between 125gn and 175gn.
6	Heating test(130°C)	No fire/No explosion	The cells are fully charged with standard charging condition, and put into incubator with nature air or cycled air convected, heat battery by velocity of 5°C ±2°C/min to130°C±2°C,and maintain for 10mins.
7	TemperatureCycling Test	no leakage, no fire, no explosion	The fully charged batteries are placed in a test chamber and subjected to the following cycles: a) Raising the temperature to 75°C ±2°C within 30 minutes and maintaining this temperature for 6 hours. b) Reducing the temperature to minus 40°C ±2°C within30 minutes and maintaining this temperature for 6 hours. c) Repeating the sequence for a further 9 cycles. d) Afterthe 10th cycle, storing the batteries for 24 hours prior to examination.
