Q: How can you guarantee the quality?

A: Quality is priority. We always attach great importance to quality control from the very beginning to the end of the production.Every product will be fully assembled and carefully tested before packing and shipping.

Q What is your company’s advantage?
A: We only supply high level quality of lithium battery and we have a strong design center, we also provide high quality after sale service.

Q: Do you accept OEM/ODM?
A: Yes, it is avaliable.

Q: What is your payment terms?
A: Sample payment through Paypal or Western Union, and mass order by T/T or L/C.

Q: How to repair the battery?: To the battery in accordance with the 0.1C current discharge, record the discharge time. Its discharge current multiplied by the number of hours of time, is the battery repair capacity. If the Chongqing battery capacity to reach the nominal capacity of more than 70%, the end of the repair.

Q: How is the capacity of the battery defined?: The capacity of the battery unit is AH (safety) is the product of current and time.

Q: What is the difference between a maintenance-free battery and a conventional battery?: As a result of maintenance-free batteries using lead-calcium alloy grille, the amount of water generated when charging less water evaporation, coupled with the shell with a sealed structure, the release of sulfuric acid gas is also very small, so it compared with the traditional battery, With no need to add any liquid, the wiring pile head, wire and body corrosion less anti-overcharge capacity, starting current, power storage time is long, by the car people welcome.

Q: How to determine the battery is good or bad?: General side maintenance has an observation hole if it is green to prove that the battery is normal if it is black to prove that the battery does not save electricity. There is to observe whether there is liquid exudation, if any, proved to be bad. Finally, you can touch the hand, such as feeling the battery around the plane has proved proof bad.

Q: How to deal with waste batteries?: The old battery is ground and then sent to the furnace for heating, then the volatile mercury can be extracted, the temperature is higher when the zinc is also evaporated, it is also precious metals. Iron and manganese fusion after the steel to become the required ferromanganese alloy.

Q: What are the hazards of battery over discharge?: The battery discharge to the standard termination voltage when the internal resistance will become larger, the battery electrolyte concentration will become very thin, especially the battery plate micropores and battery plate surface these two points are almost neutral; battery over discharge because of Internal resistance will become larger, so the battery will appear inside the phenomenon of heat, the battery volume will appear fever expansion.

Q: Maintenance-free battery how to detect it?: Keep the battery surface clean. If the discovery of solid oxide on the pole, it should be timely with hot water pouring, to be removed, so as not to affect the pole and the terminal between the continuity. After cleaning up, wipe the battery surface, in the pole and the terminal cast on the butter to ensure that the pole is not oxidized.

Q: What is the meaning of the battery above 12v65Ah?: 12V is said to be the voltage, 65Ah is the current. (A is the unit of current. H is the time unit .1 hours.)

Q: 80ah how much battery storage capacity?: Is 80AH. Understood to discharge at 80 amps for about 1 hour (but not to say that after 1 hour is finished, there is still electricity). In theory, this is your battery power.

Q: How does the battery increase the voltage?: You can use the same battery in series, with 5 12v battery in series becomes 60v, if you need the current is relatively small, you can use DC-DC module to 12v voltage rise to 60v.
