Warranty after sales


Jentebattery after sales mode
We have independent battery maintenance and after-sales service in Britain, the Netherlands, France, Canada, Australia, Russia and Japan. Maintenance personnel have rich repair experience, and battery maintenance generally takes no more than 2-4 working days. We deliver the batteries that need to be repaired through ups, DPD, FedEx and DHL. If the battery has quality problems during the warranty period, we will bear all expenses. If the battery has quality problems within three months, we will replace it with a new battery free of charge. At the same time, we support the storage of the batteries you ordered to help you maintain the batteries daily. You can ship quickly from the warehouse when you need it.


Why can we produce high quality batteries


Battery cell impact test


The cells used in the battery have undergone strict impact test to ensure that the battery cells are brand new. The battery cells will not catch fire or explode half an hour after impact.













High current overcharge over discharge


We will overcharge and overdischarge according to the specifications of each battery cell. Most battery explosions occur during
charging. We pay special attention to this test link. For each batch of order battery cells, we will test whether the cell safety
valve starts normally under overcharge environment. Whether over discharged cells will produce high temperature fire.







High and low temperature test


The battery cell will withstand 45-55 ° high temperature discharge. The cell shall be able to discharge normally, without short circuit and spontaneous combustion within the cell, and the capacity shall be greater than 99%. The battery cells shall discharge at - 15-20 ° low temperature, the capacity shall be greater than 80%, and the instantaneous starting current shall be greater than 5C







Jentebattery comprehensive test instrument

After the battery is produced through multiple processes, it needs to go through circuit test to detect whether the internal circuit of the battery is unobstructed and whether each function of the battery is normal. Whether the solder strength of cell connection bridge is qualified, etc. In addition, we will also test whether the core BMS function of the battery, the response speed of charge protection and discharge protection, and the cell balance function of BMS are normal.






Complete battery cycle test

After the completion of battery production, the final whole battery will be charged and discharged at a high speed to ensure that
the cell bridge inside the battery can withstand a long-lasting high-temperature current. The battery shall be continuously
energized and not at high temperature during discharge. Battery capacity output reaches 99.5%.The battery BMS shall work normally during discharge and charging to protect the battery.






JenteBattery Vibration test


Test whether the battery function circuit inside the battery case is welded firmly. Whether the battery pack is firmly fixed in
the battery case. There shall be no abnormal noise during battery vibration. After high-speed vibration, the external functions of
the battery can work normally. The battery packaging needs to be firm.
