Electrical Characteristic for power tool rechargeable Li-ion battery supplier

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.

If the cell is kept as ex-factory status (50% of charge), the 0.2C recoverable capacity rate is more than 90%.

1 month -20°C ~ 60 °C

2 months-20°C ~ 40 °C

3 months-20℃~ 25 °C

Appearance

There shall be no such defect as deep scratch, flaw, crack, rust, leakage, which may adversely affect commercial value of the cell.

Package

The cells are packed with JIANGSU SUNPOWER CO.,LTD. standard carton box, which hold four inner boxes. There are 100pcs 18650 cells per inner box. And the inner box and outer box identifies battery capacity, voltage and impedance information.

Warranty Period & Product Liability for High security lithium ion battery

Storage of power tool 18650 battery

The cell shall be stored at the environmental condition of -20℃- 45℃ and 65%±20% RH. The voltage for long time storage shall be 3.5V-3.7V range. If the cell has to be storied for a long time (Over 3 months), the environmental condition should be: Temperature: 23℃±3℃Humidity: 65%±20％RH；please activate the battery once every 3 months according to the following method: Charge with current 0.2C until the voltage achieve to 3.7V.
