Applications Delta battery 12V65AH battery to make it more broad a battery UPS system is an important part of it is directly related to the merits of the reliability of the entire UPS system, however, but is a whole battery UPS system MTBF Time (MTBF) of a device shortest. If the user is able to proper use and maintenance, will be able to extend its life, otherwise their life will be shortened. Currently in the UPS batteries are widely used as energy storage devices. Battery basic energy processes: energy → chemical energy → electricity, batteries before charging them with a DC power supply, electrical energy is converted to chemical energy stored up, when the electricity supply is interrupted, UPS relies on the energy stored in the battery to maintain its inverter The work, in this process, played a role in connecting the battery, it can be said, no matter how complex UPS, its performance ultimately depends on its batteries, long battery failure, no matter how good UPS can not provide backup functionality. UPS generally 220V AC output to drive high power electrical equipment. Industrial battery maintains a daily maintenance 1, the battery should be discharged after each immediately charged. 2, each of the discharge, not exceed 80% of the total battery capacity. Second, the weekly maintenance of a cable between the screw to see whether the fixed cells. 2, if the battery is not equipped with active dosing system, after charging, to see the height of the electrolyte, lower than the permissible level, to increase the eligibility rules of distilled water to the height of the electrolyte too, want to rule out of heights . 3. Check the battery box or without water, the water must be found immediately dry. Third, a monthly maintenance before charging is completed, view all the electrode unit and battery voltage, and make records. 2, after charging is completed, you should measure the density and temperature of the electrolyte in each cell, and make records, if there is a big difference between the measured value once, should ask the professionals to view. Fourth, maintaining an annual battery once a year by a professional view of the insulation resistance and battery forklift insulation resistance. The insulation resistance of the battery is 50 rules ohms / volt. The entire battery (voltage can reach 220 volts) at least 1000 ohm resistor. 2, according to the instructions on the charger once viewed, and ensure that all function properly. Technical parameters, product size, product maintenance services. Delta 6-GFM (7AH-200AH) Series VRLA Battery (6-year life) Type: 12V Series Features: Designed for UPS applications designed for the financial, telecommunications, electricity, railways, insurance, transportation, education, government, military, manufacturing, business and other systems product technical parameters: Delta company is the development, production, sales and service in one of the professional power supply manufacturers, is "National Torch Program" of the bearers, the State Science and Technology identified The "national key high-tech enterprise", the company established the ISO9001 international quality management system based on large-scale production, the ups power supply, DC power modules, inverters, batteries and other areas in a leading position, has become the most scale modern power products one of the manufacturers. 6-GFM series VRLA batteries for UPS applications specially designed, superior performance, the technology is mature, with a safe, reliable and maintenance effort, which is widely used in finance, telecommunications, electricity, railways, insurance, transportation, education, government, military, manufacturing, business and other systems. Maintenance-free professional design uses highly reliable professional VRLA design, effectively ensure that the battery does not leak (infiltration) liquid, mist-free, non-corrosive gases generated during charging and basic reduced electrolyte is absorbed in use When without adding water, rehydration and electrolyte specific gravity measurements. Long life of the grid and unique alloy formula designed to effectively resist plate corrosion; excellent large current discharge characteristics, reliable and fast charge capability, excellent deep discharge recovery capabilities to ensure the battery life. Float design life of up to 6 years. Minimal self-discharge current of high-quality high-purity material design, self-discharge current is very small, the capacity loss caused by self-discharge is less than 4% per month, less maintenance work client battery stored.
