2. Safety performance
How about the safety performance? The following info. is the result of our test.
| 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 explosion, No fire |
| 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 11.6kPa (this simulates an altitude of 15240 m) held at that value for 6 h. | No explosion, No leakage, No fire |
| 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 explosion, No fire 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 explosion, No fire |
| 5 | Over charge test | After standard charge, continue to charge with a constant voltage 4.6V per a cell, holding 8h. | No explosion, No fire, No leakage |
| 6 | Soak Test | Put the batteries into clean water, be soaked for 24 hours. | No break, No fire |

Part of factory view:
Waranty:
We give 1 year warranty. If the battery has problem coz of our
quality issue, We will give replacement any time.
Q&A:
1. Q:How to start the cooperate?
A: Lets start with the sample orders. In 3-5days will be ready the
samples, then you test.We make the standard according
the data sheet which we give.Once you confirm the quality, we can
talk for further.
2. Q: How long to make the cargos?
A: Need 30day around if we dont have the stock of that model. Coz
need strictly test and high temperature,high voltage life ageing as
well in every single pc. That will takes a fixed date.
3. Q: What will be the packing?
A: We are using blister pallet packing in each battery. and then
fold all packing in one ctn.
4. Q: Can the connectors be customized?
A: Yes, we can choose the right connector according your
requirement.Or help to match your device.
For more please contact me freely, wish my 12years experience in
battery area can help you in your project.
