(1) to maintain an appropriate 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. UPS is connected to the mains due to long-term, high-quality power supply, power outages are rare use of the environment, the battery will be long-term in a floating charge state, a long time will cause the battery to chemical energy and electrical energy into each activity decreased, accelerated aging shorten life. Thus, generally every 2 to 3 months to be completely discharged once, discharge time can be determined based on the battery capacity and load size. After a full load discharge is completed, according to the provisions of more than 8 hours to recharge. Recommended products :( maintenance-free batteries, SORENSEN batteries.
