Discharge rate capabilities

A）1 C5A ≥100% B）10 C5A ≥95% C）15 C5A ≥90%

Standard charged under the condition of   normal atmospheric pressure and the environmental temperature of 23℃±3℃   and45%～85%RH, then rest for 30mins and discharge at1C5A、5 C5A、10 C5A to the   discharge cut-off voltage respectively. Charge/discharge cycle can be   conducted for 3times before meeting the Standards（the same below）

2

capacity retention and recovery

Residualcapacity≥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 C5A to 2.75Vmeasuring residual capacity; Then   standard charge/discharge measure recoverable capacity.

3

Low Temperature Performance

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 0.2C5A down to the end-of-discharge   voltage 2.75V.

4

Cycle Life

≥300cycles

Charge: The cell shall be charged in   accordance with RapidCharge condition. rest for 10mins.Discharge: 10C5A   discharge to 2.75V, one cycle is finished, then rest for 30mins. Then repeat   above steps, when capacity is less than 80% of initial capacity, the battery   life is over.

1

Overcharge

No fire、No explosion

After standard charge, rest for 10mins; then charge at constant   current of 3C5A to 10V.(or charge at 3C5A for 90mins). 

2

Forced discharge

No fire、No explosion

The battery to be discharged with standard discharging condition,   Inverse charge current =1C5A；time: ≥  90mins 

3

Short Circuit test

No fire、 No 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 case temperature   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 initial 3ms, 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 to 130°C±2°C,and maintain for 10mins. 

    7

Temperature 
   Cycling 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 within 30 minutes and maintaining this   temperature for 6 hours. c) Repeating the sequence for a further 9 cycles. d)   After the 10th cycle, storing the batteries for 24 hours prior to   examination.
