Applications range radio communication system power appliances, medical equipment and instrumentation, uninterruptible power supply UPS office automation systems start shipping locomotives, railway coaches and other portable electrical power control switch lighting, lighting power battery HZY12-150 US sea-battery maintenance and upkeep : In the process of using the UPS system, 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 batteries: ?? a ?? 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 shorten battery life ?? accelerate. 2. ???? Regular 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 increases as the load is increased, the use should be reasonable to adjust the load, such as controlling computers and other electronic equipment The use of several. 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. Note ????????????? meaning one, no electrolyte leakage under normal use, no cell expansion and rupture. 2, good resistance to shock: fully charged battery completely fixed to 4mm amplitude, frequency 16.7Hz vibration 1 hour, no leakage, no cell expansion and cracking, open circuit voltage is normal. 3, good impact resistance: the battery is fully charged state natural height from 20cm down to 1cm thick hardwood board 3 times. No leakage, no cell expansion and cracking, open circuit voltage is normal. 4, resistance to over-discharge: 25 degrees Celsius, the battery is fully charged state resistance of the discharge given 3 weeks (equivalent resistance of the battery discharge requirements 1CA resistance) to restore the capacity of more than 75%. 5. Good resistance to overcharge: 25 degrees Celsius, a fully charged battery charging status 0.1CA 48 hours, no leakage, no cell expansion and cracking, open circuit voltage is normal, the capacity retention rate of over 95%. 6, resistance to high current: fully charged battery discharge 2CA 5 minutes or 10CA discharge for 5 seconds. No conductive part of the fuse, without the appearance of deformation on a custody. Please note that the temperature should not exceed the range of -20 ℃ ~ + 40 ℃ 2 during storage. The battery must be kept in a fully charged state when the storage battery. Because in transit or during storage due to self-discharge will lose some capacity, please add electricity use. 3. When the long-term storage, to compensate for self-discharge during storage, please add electricity. When custody in excess of 40C conditions have bad impact on battery life, avoid! 4. Do keep in dry and cool, well-ventilated place. UPS battery 5. As in custody or transferred during battery accidentally get wet packing, packaging cartons should be removed immediately to avoid being water wet cardboard box becomes a conductor caused by the positive terminal of the battery discharge or burn. Battery Charger Battery Charger design affects the reliability of UPS batteries very important part of the battery charging conditions have a significant impact on battery life. If the battery has been in a constant or "float" type of electrical charge state, the UPS can be improved to maximize battery life. In fact the life of the battery charge state is much longer than the life of a simple storage conditions. Because the battery charging can delay the natural aging process of the battery, so regardless of running or UPS shutdown state should keep the battery charged. Effect of reliability of the battery cell voltage the battery is a single "primary cells", each of a primary battery voltage of about 2 volts, primary batteries connected in series to form a high-voltage battery, a 12 volt battery composed by six primary batteries, 24-volt battery from a primary battery 12 composed like. When the UPS battery charge, each primary batteries in series have been charged. Original battery performance will lead to some slightly different primary battery charging voltage is higher than other primary battery, the battery will advance this part of aging. As long as a certain concatenated primary battery performance, the performance of the entire cell will also decrease. Test proved battery life and the number of the original series the battery, the battery voltage is higher, the faster aging. UPS UPS battery capacity is constant, the design should be as far as possible so that the battery voltage is low, so the longer the UPS battery life, battery voltage for a certain time, you should choose a small number of voltage primary battery cells in series, do not select the number of the original multi-voltage low The battery cells in series. Some manufacturers UPS's battery voltage is relatively high, because the capacity of a certain time, the higher the voltage, the less current, the wire can be chosen smaller and smaller power semiconductors, thereby reducing the cost of UPS. Capacity 1KVA UPS battery voltage so generally 24ˉ96V. ?
