Information services: 1, the product manual provided with the product and installation instructions. 2, according to user requirements design, installation, and provide product design and installation drawings. 3, according to user requirements to provide information about the performance of products and a variety of characteristics. 4, to provide training materials and training relevant information required by the user. Battery Care and Maintenance: Use UPS 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 due to battery failure caused by a host failure or UPS is not working properly is about 1/3. Thus, strengthening the proper use and maintenance of the UPS battery to extend battery life and reduce the failure rate of UPS systems, 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 the battery: (1) 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. UPS batteries currently used are generally VRLA batteries, universal design life of five years, which can be achieved in the battery manufacturer demanding environments. Less than the required environmental requirements, there is a great difference in the length of its life. In addition, the increase in ambient temperature can cause the 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. (2) periodic charge and discharge. UPS power supply system float voltage and discharge voltage at the factory have been commissioning rating, while the size of the discharge current is increased as the load increases, the use should be reasonable to adjust the load, such as computers and other electronic control the use of several devices. Under normal circumstances, the load should not exceed 60% UPS rated load. Within this range, the battery does not appear excessive discharge.
