As a state owned company, we have been in domain of clean energy products and enery storage products for nearly 20 years. And with registered capital of nearly RMB 702 millions and 1500 employees in China, we have a strong reserach team to support our clients.


For controlling our quality of products, we have our own factory and we also make much investment in lithium. 


And our R&D team could design different kinds of products according to demands of clients to make sure that our clients could apply products in different scenes. We have servral advanced production lines for diffrent uses. 


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: What are the hazards of battery over discharge?
When the battery discharge current is large, the heat will become more obvious, there will be serious heat generated when the battery deformation, when the concentration of lead sulfate is particularly large, will form a larger crystal particles, that lead to the battery Internal irreversible sulfation.
Q: Maintenance-free battery how to detect it?
Do not always check the color of the electric eye for maintenance-free batteries. Green for the full power; black for the lack of electricity, need to be added to charge; gray or light yellow for the electrolyte is insufficient, because maintenance-free battery can not add liquid, should immediately replace the battery.
Q: What battery does the van use?
The most obvious feature of lead-acid batteries is the top of the plastic cover can be unscrewed, there are ventilation holes above. These fillers are used to fill pure water, check the electrolyte and the use of exhaust gas. In theory, lead-acid batteries need to check the density of each electrolyte and the level of liquid, if there is a need to add distilled water. But with the upgrading of battery manufacturing technology, lead-acid battery development for the lead-acid maintenance-free batteries and colloidal maintenance-free batteries, lead-acid batteries do not need to add electrolyte or distilled water. Mainly the use of positive electrode to produce oxygen can be absorbed in the negative oxygen cycle, to prevent water reduction. Lead-acid water batteries are mostly used in tractors, tricycles, car start, etc., and maintenance-free lead-acid battery wider range of applications, including uninterruptible power supply, electric vehicle power, electric bicycle batteries. Lead-acid batteries according to the application needs to be divided into constant current discharge (such as uninterruptible power supply) and instantaneous discharge (such as car to start the battery).
Q: What are the advantages of maintenance-free batteries?
Maintenance-free battery using lead-calcium alloy grille, the amount of water generated when charging less water evaporation is low, with the shell with a sealed structure, the release of sulfuric acid gas is also very little, so with the above advantages.
Q: The role of the battery?
Battery is widely used, can be used for ups, electric cars, scooters, cars, wind energy solar systems, security, and so on.
Q: What kind of battery is divided into?
Maintenance-free battery due to its own structure on the advantages of electrolyte consumption is very small, in the life of the basic need not add distilled water. It also has a shock, high temperature, small size, self-discharge characteristics of the general life is generally ordinary Twice the battery. There are two kinds of maintenance-free batteries on the market.
Q: What is a maintenanceable battery?
It also has a shock, high temperature, small size, self-discharge characteristics. Life is generally twice the ordinary battery.
Q: Lead-acid battery how to maintain?
After 5 hours of repair, the excess electrolyte is sucked out with a straw, and if the electrolyte is sucked out into black, it indicates that the battery is severely grounded and that the battery is difficult to repair.
