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 | Over Discharg | (After standard charge. Cells are discharged at constant Current of 0.2C to 2.0V, and the positive and negative terminal is connected by a 30Ω wire for 24 hours. Cell Condition: Fresh, Fully charged cell.) | No fire, No explosion |
5 | Over charge test | After standard charge, continue to charge with a constant voltage 4.8V 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 |
Caution:
Risk of Fire , Explosion or Burns
DO NOT Short circuit
DO NOT Reverse connections from charger to battery
DO NOT Disassemble
DO NOT Throw into fire or incinerate
DO NOT Heat above 70C
