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 and the 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 described the 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 which is specified in the technical document of the company,the capacity(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)after standard charge, then measure final status and residual capacity at 0.3 C5A to 2.0V or 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 90 days 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 be measured 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 explosionno 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. |
