US SORENSEN battery 1, when the simple maintenance of gas generated inside the rechargeable battery is reduced to the basic electrolyte is absorbed, basically no electrolyte decreased. 2, holding a liquid electrolyte is absorbed in a high special partition, the flow state is not maintained, so even if the fall can also be used. (Fallen more than 90 degrees can not be used) 3, superior safety performance due to extreme overcharge operation errors caused by too much gas can be released to prevent rupture of the battery. 4, self-discharge small production with a special lead-calcium alloy grid, the self-discharge to a minimum. 5, long life (design life of 3 to 5 years) the economy is good battery grid using good corrosion resistance special lead-calcium alloy, while using special separators can keep the electrolyte, and then pressed at the same time with a strong positive plate active material, to prevent the loss, it is a long life, economy batteries. 6, the internal resistance due to the small resistance, good high-current discharge characteristics. 7, after deep discharge has excellent resilience in case of long-term discharge, as long as the full charge, basically does not appear to reduce capacity, the United States will soon be able to resume SORENSEN SAL Series batteries use the latest quotations ups power supply system in the process, people often one-sided that the battery is maintenance-free and not take this seriously. However, our data show that the proportion of ups due to battery failure caused by a host failure or not working properly is about 1/3. Thus, strengthening the proper use and maintenance of ups battery for extended battery life and lower ups power system failure rate, with more and more important. In addition to the optional battery than regular brands, the following aspects should be the proper use and maintenance of batteries:? 1. To maintain the proper ambient temperature. Important factors that affect battery life is the ambient temperature, ambient temperature is usually the best battery manufacturers requirement is between 20 ℃ ~ 25 ℃. Although the temperature rise of the battery discharge capacity has increased, but the cost is greatly reduced battery life. According to tests measuring the ambient temperature once more than 25 ℃, every increase of 10 ℃, the battery life would be shortened by half. Currently ups are generally used batteries VRLA batteries, universal design life of five years, under which the battery manufacturer requirements of the environment? Can be achieved. Less than the required environmental requirements, there is a great difference in the length of its life. In addition, the increase in ambient temperature will cause? Battery internal chemical activity increased, resulting in a lot of heat, in turn prompting the ambient temperature rises, this vicious cycle will? Accelerate shorten battery life power supply, power plants , telecommunications, signal control and remote control, emergency energy supply, data systems, ups, alarm and security systems, emergency lighting and circulation occasions custody on a routine inspection and maintenance on a regular basis to check the battery, if there is the appearance of dust and other contamination when water or cloth soaked in warm water for cleaning. Do not wash with gasoline, bananas, water and other organic solvents or oils, in addition to avoid using chemical fiber cloth. 2, when the float, the index value on the total np battery charging voltage or dial voltmeter should investigate the reasons for the deviation reference values ??shown in the following table (? .05v / Single cell) and processed. Use distinction benchmarking project processing floating charge rechargeable battery voltage with a voltmeter to measure the overall total voltage charger 2.275 (single cell 20 c) If the difference x number of cells corrected to the reference value 3, using the ups and other convertor Please note that to avoid backflow current flows from the converter. The line can not avoid this, set the pulse current flowing into the battery value (rms) controlled 0.1ca below. 4, based on the average battery environment, refer to replace the battery temperature during the replacement period np 20 c within (room temperature) within 3-5 years 30 c 40 c within 2.5 years 1.4 years
