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.
3NormalStorage/HighTemperatureStorageResidual 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.

2.Safety Performance  

NO.ItemRequirementsTest Method
1Over chargeNo fire,no explosionAfter standard charging,then Charge at 3C5A to 10.0V
2Over dischargeNo fire,no explosionAfter standard charging,discharge 0.3C5A to 0V at 20°C±5°C
3Short Circuit at Room TemperatureNo fire,no explosionAfter 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
4DropNo fire,no explosion,no leakageAfter 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.
5Hot OvenNo fire,no explosionAfter standard charging. Keep the battery in the box with constant temperature of 85°C±2 °C and remained for 2hours at this temperature.
6CrushNo fire,no explosionAfter 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)
7NeedlepunctureperformanceNo fire,no explosionAfter 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.
