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: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:Maintenance-free battery how to detect it?
Battery pole Pole terminal has corrosive material without treatment, as long as no loose on it. If the appearance of the corrosive material, the inner surface of the terminal will also be corrosion, resulting in increased resistance, affecting the normal battery charging and discharge, it must be promptly processed.
Q:What kind of battery is divided into?
At present, we used the car battery is divided into three categories, namely, ordinary batteries, dry batteries and maintenance-free batteries three.
Q:Lead-acid battery how to maintain?
Open the rubber cap, exposing the exhaust raft, you can see the battery inside, some of the battery exhaust cutting can be unscrewed.
Q:What battery does the van use?
The battery is mainly composed of tube positive plate, negative plate, electrolyte, separator, battery compartment, battery cover, pole, injection liquid cover and so on. The electrode of the exhaust type battery is made of lead and lead oxide, and the electrolyte is an aqueous solution of sulfuric acid. The main advantage is the voltage stability, the price is cheap; the disadvantage is lower than the energy (that is, per kilogram of battery storage power), short life and routine maintenance frequently. Old ordinary battery life of about 2 years, and the need to regularly check the height of the electrolyte and add distilled water. However, with the development of science and technology, lead-acid battery life becomes longer and maintenance is also more simple.
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:What is a maintenanceable battery?
This is relative to a maintenance-free battery. Maintenance of the battery needs to be supplemented with electrolyte to ensure work, while maintenance-free is not required.
Q:How is the capacity of the battery defined?
100AH capacity of the battery, fully charged after the 100A current discharge can be an hour to put the power finished. 50A current is 2 hours put away! 20A is 5 hours! Of course this is the theoretical value, in fact it is impossible to have a constant current discharge.
Q:How to deal with waste batteries?
The rest of the various types of waste batteries are generally shipped to a special toxic, hazardous landfill, but this approach not only cost too much but also cause waste, because there are many useful raw materials available.
Q:Battery 200ah / 104 what does that mean?
Lead-acid battery nominal voltage is 2V / (each or monomer), but in fact will be higher than 2V, so the actual use and charging equipment for the matching will use 104, also useful 103, also useful 108 Only.
