Wansong official website wansong battery lead-acid batteries in the role of telecommunications systems and problems of lead-acid battery is the communication power system is an important component of the DC power supply system, which serves as a backup DC power supply, mainly responsible for the sudden interruption in electricity Under the circumstances, to continue to provide a safe, stable and reliable power protection for the traffic load, to ensure the normal operation of switching, transmission and other communication devices. Therefore, lead-acid batteries in the discharge process can provide meaning to the actual capacity of the load to ensure the smooth flow of communication is very important. However, lead-acid batteries lead acid factor after a period of use, are often easy to fall off due to the active substance, or plate deformation grid corrosion, curing, etc., leaving the capacity gradually reduced until failure. Find behind the battery, and be dealt with in order to eliminate hidden dangers, that the majority of the lead-acid battery maintenance staff. Over the past decades we have been using anti-acid proof lead-acid lead-acid batteries, and accumulated some experience. But because such a cumbersome battery maintenance methods, have now been added to the water-free, flexible installation, small footprint and does not form a mist of VRLA lead-acid battery (VRLA) replaced. In recent years, because of VRLA lead-acid batteries are widely used in domestic production of VRLA manufacturers more and more, the production scale and skill levels, a lot of problems, VRLA battery in the early 1990s there have been many domestic use new problems not encountered before, but because it is a new technology, because some fault has not been fully grasp, only to establish effective management method on the maintenance, in order to avoid major problems. Quanzhou wansong Power Technology Co., Ltd. is a Hong Yi Industrial (Hong Kong) Ltd., Quanzhou wansong Power Technology Co., Ltd. invested in mainland China battery manufacturers. The company covers an area of ??over 20,000 square meters, the main plant building area of ??16,000 square meters, the annual production capacity of 1.5 million kVA, is China's large research, development, production and operations in one of the professional production of various types of VRLA sealed lead-acid battery manufacturers. The company mainly produces three series of more than 80 kinds of battery products, widely used in transportation, communications, electronics, computers uninterruptible power supply systems in the field, telecommunications, financial systems. The company has strong technical force and the international advanced level of technology, technology and equipment, use of modern management methods, the implementation of microcomputer control of production and testing aspects of the product. The company has always pursued the "quality of life, to management efficiency," the purpose of establishing a "quality-oriented, customer-oriented" quality. And passed the ISO9001: 2000 quality management system certification and American UL certification. Product quality inspection agency by the state authority, the indicators can reach the standards. Selling products, exported to Europe, America and Southeast Asia, with its high-quality products, excellent service by users of all ages in all areas. High quality AGM deep cycle lead-acid battery separator for applications such as uninterruptible power supplies and portable equipment, solar energy systems and wind energy systems, medical equipment and so on. Customer-oriented: In a customer-oriented philosophy, Quanzhou wansong dedicated high-speed effective for customers from around the world to provide quality and cheap lead-acid batteries. Through intensive training program, we learned of the latest knowledge of customer technical support, we continue to meet customer needs. Battery Product advantages: 1, good safety performance: No electrolyte leakage under normal use, no cell expansion and rupture. 2, the discharge performance: stable discharge voltage, discharge platform gently. 3, good resistance to shock: fully charged battery completely fixed to 4mm amplitude, frequency 16.7Hz vibration 1 hour, no leakage, no cell expansion and cracking, open circuit voltage is normal. 4, good impact resistance: the battery is fully charged state natural height from 20cm down to 1cm thick hardwood board 3 times. No leakage, no cell expansion and cracking, open circuit voltage is normal. 5, resistance to over-discharge: 25 degrees Celsius, the battery is fully charged state of constant resistance discharge 3 weeks (equivalent resistance of the battery discharge requirements 1CA resistance) to restore the capacity of more than 75%.
