2. Safety performance


How about the safety performance? The following info. is the result of our test.

NoItemsTest Method and ConditionCriteria
1Thermal exposure testEach 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
2Low pressureEach 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
3Short testThe 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℃
4Forced discharge testA discharged cell is subjected to a reverse charge at 1C for 90 min.No explosion, No fire
5Over charge testAfter standard charge, continue to charge with a constant voltage 4.6V per a cell, holding 8h.No explosion, No fire, No leakage
6Soak TestPut the batteries into clean water, be soaked for 24 hours.No break, No fire

The application of the polymer battery.


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.
