CSB Battery GP12400 when in the early 1990s, just use VRLA batteries, has been called "maintenance-free battery," which is actually a misleading, plus the quality of the early steps VRLA battery products are not high, often use some kind or another failure. Of course, with the development of computer technology, LSI devices are emerging, as well as switching power supply, UPS power supply technology continues to improve, the power system equipment has made no small progress, in the power supply safety and reliability aspects have been greatly improved, the power system equipment maintenance workload is reduced a lot. The main message using the CSB batteries: valve regulated lead-acid batteries as a world-class leading brands, CSB's products have been widely on uninterruptible power systems, emergency lighting and security systems and other products used in the world of communications equipment, since 1986 AD. Since its establishment, CSB has gradually become an international group thrive. CSB factories all branches throughout Asia and the Americas, with an average production of batteries supply the market more than 3 million units per month. Quality persist created CSB grow today. CSB batteries are all produced by high efficiency, maintenance-free, and access to ISO and UL certified. However, CSB is not as a full, in the future, CSB will be fully engaged in the development of high-tech and customer layer of cells in order to meet the market and the needs of each client. Under the joint efforts of more than a thousand professional staff, CSB are confident to provide you a better, more reliable products and service value. CSB advantages: · stable global sourcing: monthly production of 1.2 million (and an increase in), and in Asia, the Americas, India (evaluation) of the three production bases, providing customers worldwide supplier JUST IN TIME . · Full range of products: complete product line, and the production of different products for different industries, environment, equipment development, from 6V-4.5AH ~ 6V-12AH, 12V-2.2AH ~ 12V-100AH, 2V-200AH ~ 2V-6000AH, Applications culvert across industry, electronics, military, medical, petrochemical and other related industries. · Industry-leading new product development capability: CSB has successfully co-developed HC, HR, ET products with world-class customers, and to develop a new product every month speed communications efforts towards the development of a dedicated battery, available in different product requirements, specifications and special product development. · Professional technical support: CSB with ten years of experience in world-class telecommunications customers uninterrupted through the CSB offices on five continents and dozens of countries point of sale services of a professional engineer, and even into a tight-knit service network, enabling customers in the shortest possible time, the most satisfactory service. · Smooth communication channels: Asia-Pacific Headquarters (Taipei) and Beijing, Shanghai, Guangzhou, Shenzhen, California, Texas, Milan, Italy, Japan, Osaka, (Singapore, established in New Delhi) CSB branches and agents responsible for the global coordination of the delivery of all work in China can be coordinated by a single window for all matters directly, without language barriers of time. · Trusted partner: Since its establishment, CSB continue to grow and strive to resolve all customer needs, and grow together in the market, its work and responsible attitude to see. CSB Although founded only 14 years, but its achievements have been recognized by the industry and deep affirmation, undeniable CSB battery industry has become the most shining star for some small power UPS, UPS back-up time in order to increase capacity and increase external battery pack, it will bring some use problems: 1) low power UPS charger power is limited, can only provide the maximum charging current 2-3A general machines, time-lapse chargers the charging current is limited. If the optional high-capacity external battery pack, charging in a certain period of time due to insufficient charging current, voltage increase is limited, often the past will affect battery life. 2) Because the machine comes standard with a small capacity battery pack, usually 12V / 5AH, 12V / 7AH, and with a battery monitoring. If not removed the internal battery, and external large-capacity battery pack, such as 12V / 65AH, 12V / 100AH ??and so no battery monitoring, battery run in parallel in two different capacities. When the battery is charging, the battery internal resistance due to the two different charging current is not balanced, not according to the standard charging current value, it will seriously affect the battery life. Will cause the charging current hour, within the specified time is not easy full battery when the battery charging current exceeds 0.1C10 value, but also make large current battery overcharge, and seriously affect the battery life. When the battery is discharged, large-capacity battery will charge back to a small capacity battery, which will affect the battery discharge time and battery life.
