All testing under full capacity
2.2 Reliability Test
| No. | Items | Standards | Testing Methods |
| 1 | Vibration Testing | The appearance of battery should not leakage, break or explosion | Fix a charged battery on a vibrating table, vibrate it for 90 minutes in three mutually perpendicular directions at the 0.8mm resonance. The frequency is to be varied at the rate of 1hz/min between 10 and 55 hertz. |
| 2 | High Temperature Discharge Testing | The battery should be no remarkable breakage, distortion. Discharge time should not less than 255mins | Place a full charged battery under the environments of 55ºC for 2 hours. Discharge it at the current of 0.2C to the cut-off voltage. Then keep it at 20ºC±5ºC for 2 hours. |
| 3 | Low Temperature Discharge Testing | The battery should be no remarkable breakage, distortion. Discharge time should not less than 180 minute | Place a full charged battery under the environments of -20ºC for 15-24 hours. Discharge it at the current of 0.2C to the cut-off voltage. Then keep it at 20ºC±5ºC for 2 hours. |
| 4 | Constant Humidity & Temperature Testing | The battery should be no remarkable breakage, distortion. Discharge time should not less than180mins | Place a full charged battery under the environments of 40ºC and 90% - 95%RH for 48 hours. And keep it in the room temperature for 2 hours. Then discharge it at the current of 0.2C to the cut-off voltage. |
| 5 | High & Low Temperature Storage | The battery should be no remarkable breakage, distortion. And charge/discharge normally | Place a full charged battery in a oven with 55±2ºC for 2 hours, then keep it under 20±5ºC for 4hrs, then place it in a oven with -20±2ºC for 2 hours, then keep for 4 hours under 20±5ºC, cycle as high temperature-normal temperature-low temperature-normal temperature-high temperature for 10 times |
3. BATTERY PACK SAFETY TEST
3.1 Testing condition (Unless Special Requirements)
Temperature:20±5ºC Relative Humidity: 45~75%
Atmosphere Pressure: 86~106kPa
All testing under full capacity
3.2 Battery Pack Safety Test
| No. | Items | Standards | Testing Methods |
| 1 | Short-Circuit | The battery should be no remarkable breakage, distortion. And charge normally. | Use a resistor with less than 0.05Ω to make the battery short circuit for 1 hour. The appearance and characteristics are normal. |
| 2 | Over Discharge Protection Test | The battery should be no remarkable breakage, distortion. Appearance and charge are normal. | Discharge the battery at the rate of 0.2C with the load of 30Ω for 24h . Charging for 10sec with specified adapter , and check the voltage(≥8V) |
| 3 | Impact Test | The battery should be no explosion or catch fire | Place a full charged battery on a flat and put a stainless steel stick (Diamond 7.9mm) in the middle of the battery upright . Beat the steel stick with 9.1Kg |
