1.Electrical characteristics

NO.	Item	Requirements	Test Method
1	Dischargerateperformance	Discharge Capacity/Nominal capacity×100%A) 0.3C5A ≥100%B) 1.5C5A ≥90%	a)Standard charge at 0.3C5A under the condition of normal atmospheric pressure andthe environmental temperature of 20°C±5°C and45%~80% RH, discharge at 1I3/4.5I3(A)to 2.0V or the cut-off voltage which is specified in the technical document of the company.b)the capacity(AH)=the discharge time*discharge current,and then is describedthe percentage of the nominal capacity(Charge/discharge cycle can be conducted for 3times before meeting the Standards(the samebelow).
2	High-lowTemperatureDischargeperformance	Discharge Capacity/Nominal capacity×100%A) 55 °C ≥95%B) -20°C ≥55%	After Standard charging. Then store it at the constant temperature of 55±2°C for 5h(of -20±2°C for 20h),and discharge at 0.3C5A to 2.0V or the cut-off voltage whichis specified in the technical document of the company,thecapacity(AH)=the dischargetime*discharge current,and then is described the percentage of the nominal capacity.
3	NormalStorage/HighTemperatureStorage	Residual Capacity≥Nominalcapacity*80%Recoverable capacity≥Nominal capacity*90%	Store for 28 days(Store for 7 days at the constant temperature of 55±2 °C)afterstandard charge, then measure final status and residual capacity at 0.3 C5A to 2.0Vor the cut-off voltage which is specified in the technical document of thecompany;After charge/discharge(0.3C5A/0.3C5A)cycle can be conducted for 3 times,recoverable capacity will be tested.
4	StoragePerformance	recoverablecapacity ≥nominalcapacity *95%	Standard charge and then rest for 1H,then discharge for 2H at0.3C5A,storge for 90days at 20°C±5°C,After standard charge,then discharge at 0.3C5A,(Charge/dischargecycle can be conducted for 5 times before meeting the Standards(the same below)
5	Cycle Life	Discharge Capacity≥Nominal capacity*80%	Conduct 0.3C5A/0.3C5A cycle for 2000 times.The discharge capacity shall bemeasured after 2000 cycles.

2. Safety Performance 

NO.	Item	Requirements	Test Method
1	Over charge	No fire,no explosion	After standard charging,then Charge at 3C5A to 10.0V
2	Over discharge	No fire,no explosion	After standard charging,discharge 0.3C5A to 0V at 20°C±5°C
3	Short Circuit at Room Temperature	No fire,no explosion	After standard charging, keep the battery into a ventilation cabinet and short-circuit the positive and negative terminals directly (general resistance shall be less than or equal to 5mΩ) for 10 minutes
4	Drop	No fire,no explosion,no leakage	After standard charging, then let it self fall off from a height of 1.5m(the lowest height)to a rigid wooden board with the thickness of 20mm. The drop is implemented one time for every face.
5	Hot Oven	No fire,no explosion	After standard charging. Keep the battery in the box with constant temperature of 85°C±2 °C and remained for 2hours at this temperature.
6	Crush	No fire,no explosion	After standard charging, keep the battery on the bracket1. Extrusion direction:Perpendicular to the direction of maintaining pressure on the battery plates.2. Extrusion headdress product:≥20cm3. Extrusion degree: Until the battery shell ruptured or internal short circuit (battery voltage becomes 0V)
7	Needlepunctureperformance	No fire,no explosion	After standard charging, keep the battery on the bracket,penetrate through it with a 3mm~8mm diameter nail near the center of its biggest surface at the rate of 10mm/s-40mm/s.
