Cell electrical characteristics:
| No. | Items | Test Method and Condition | Criteria |
| 1 | Thermal exposure test | Each fully charged cell, stabilized at room temperature, is placed in a circulating air-convection oven. The oven temperature is raised at a rate of 5 °C/min ± 2 °C/min to a temperature of 130 °C ± 2 °C. The cell remains at this temperature for 10 min before the test is discontinued. | No fire, No explosion |
| 2 | Low pressure | Each fully charged cell is placed in a vacuum chamber, in an ambient temperature of 20~25℃. Once the chamber has been sealed, its internal pressure is gradually reduced to a pressure equal to or less than 11.6 kPa (this simulates an altitude of 15240 m) held at that value for 6 h. | No leakage, No fire, No explosion |
| 3. | Short test | The fully charged battery is to be short-circuited by connecting the positive and negative terminals of the battery with resistance load not exceed 100mΩ. Tests are to be conducted at room temperature 20~25℃. | No fire, No explosion The Temperature of the Battery surface not exceeded than 150℃ |
| 4 | Forced discharge test | A discharged cell is subjected to a reverse charge at 1C for 90 min. | No fire, No explosion |
| 5 | Over charge test | After standard charge, continue to charge with a constant voltage 4.6V per a cell, holding 8h. | No leakage, No fire, No explosion |
| 6 | Soak Test | Put the batteries into clean water, be soaked for 24 hours. | No break, No fire |
