Three of the battery 12V200AH direct lead-acid battery industry status quo and development in recent years, lead-acid battery technology development, product maturity. Starting cell structure gradually upgrading, maintenance-free batteries are widely used, is still military, civilian transportation equipment important power supply unit for China to become the world's major car producer has played an important supporting role. VRLA batteries, gel batteries as a backup power source, the core components of large reserves of power, and its production has become an important basis for economic development of the industry. Lead-acid battery industry promising. The main raw material of lead-acid batteries - lead recycled repeatedly, as long as the introduction of relevant industrial policies used batteries for recycling, correctly guide the market, it can effectively solve the shortage of non-ferrous metals, lead contamination and other resources, the environment and many other issues. Therefore, the correct understanding of the status quo battery industry, identify trends and effectively solve their own problems, is the recycling of resources and building a conservation-oriented society, is an effective way to scientific development of the national economy. Low-pressure exhaust system (valve) Three of the power supply battery is equipped with a low-pressure exhaust valve, the valve is suitable for between 1 ~ 6 PSI barometric pressure, when the atmospheric pressure beyond 6PSI will release excess gas, and the gas equilibrium scratch sealed battery. Thus, excessive gas inside the battery does not occur. This useful use of low-pressure exhaust system, making three of the power supply battery tightness and security is very good. Heavy grid with heavy lead-calcium alloy grids made of three battery power supply using float or cyclic use even under conditions of deep discharge use, can adhere to a few outstanding features and longevity. Low self-discharge rate due to the heavy use of lead-calcium alloy grid, three of the power battery can keep for a long time without charging status. Three of the high power battery recovery function is still excellent even under conditions of deep discharge rechargeable sex and functional capacity of rehabilitation. UL certification and CE marking three battery power supply UL and CE certification. Our theme: UPS - Uninterruptible the serve; credibility first, customer first earn the customer's credit.! Careful promised "a penalty ten" battery 12v65ah discussion points is the intent of this item under the above conditions to extend battery life cycle number of methods are adopted, the gist of discussions battery positive and negative plates thickness, and electrolyte specific gravity is not the same charge pre-conditions on the battery capacity, GB The life cycle and the rate of 100% dod 1h number of cycles of life. For more than a research experiment content content, the choice of two tectonic plates thickness of the battery, the electrolyte specific gravity of four kinds of cooperation, manufacturing 12v, 7ah battery to perform various functions of the experiment. 1.1 EGL battery cell manufacturing 12v65ah battery manufacturers choose three positive 4 negative (positive plate thickness of 3.6mm), 4 are 5 negative (positive plate thickness of 2.8mm) to install two configurations, lead paste formulations for SUNNYWAY company number longevity lead paste recipe plate for trough technology into production, after the battery is installed parting plus four 1.27,1.29,1.31,1.33 electrolyte specific gravity, acid volume control like a single body of useful acid volume. Battery charging is completed in accordance with the technology early test battery components and internal resistance of the battery components constructed of two parting approximately 2.60kg and 2.45kg, resistance and leave about 19mω 17mω. After parting preliminary test capacity and cycle life expectancy of two types of batteries for all types of orthogonal experiment made it clear that the battery characteristics and experimental projects, all types of batteries orthogonal conditions shown in Table 1. 1.2 pre-function tests in Table 1, all kinds of batteries manufactured, respectively, and test various types of batteries 20h 3c capacity, as the battery capacity compare pre-check. 1.3 GB The life cycle of the battery capacity through pre-qualification test, in accordance with the small VRLA batteries national norms (specification codenamed gb / t 196391.1-2005) count the number of experimental approaches Shou Shou 5.18 Table 1 Category 6 test battery .
