The United States sea import agent America battery HZB12-100 battery HZB12-100 sea import agent America Haizhi battery HZB12-100 import agent battery deformation is not sudden, there is often a process. Battery in charging capacity to about 80% into the high voltage charging area, then the positive plate precipitated oxygen, oxygen through the bulkhead hole to negative electrode of oxygen in the reaction of resurrection on the cathode board: 2Pb+O2=2PbO+ PbO+H2SO4=PbSO4+H2O+ heat heat heat reaction, when the charging capacity reaches 90%, the oxygen generating speed increases negative, began to produce hydrogen. The increase of a large amount of gas makes the internal pressure of the battery exceed the open valve pressure, the safety valve opens, the gas escapes, and finally shows the loss of water. 2H2O=2H2 = +O2 = battery with the increase of cycle times, the water gradually reduced, the battery there is the following: (1) the oxygen channel becomes smooth, the cathode oxygen produced by easily reach the anode through the channel. (2) the heat capacity decreases. The biggest heat capacity in the battery is water and water loss. The heat capacity of the battery decreases greatly, and the heat generated increases the temperature of the battery rapidly.

Maintenance and maintenance of sate battery:
In the process of using the UPS power supply system, people often think that the battery is not maintenance free and not to be paid attention to. However, it has been shown that the proportion of UPS mainframe failure or abnormal work caused by battery failure is about 1/3. It can be seen that it is more and more important to strengthen the correct use and maintenance of UPS batteries, prolong the service life of batteries, and reduce the failure rate of UPS power system. In addition to the selection of regular brand battery, the following aspects should be used and maintained in the following aspects:
(1) keep the appropriate ambient temperature. The most important factor that affects the life of the battery is the ambient temperature. The best ambient temperature required by the general battery manufacturer is between 20 and 25. Although the increase in temperature increases the discharge capacity of the battery, the cost of the battery is much shorter than the battery life. According to the test, once the ambient temperature exceeds 25 degrees C, the battery life will be reduced by half by 10 degrees centigrade. At present, the batteries used by UPS are usually valve regulated lead-acid batteries. The design life is generally 5 years, which can be achieved in the environment of battery manufacturers. Without the required environmental requirements, the length of its life is very different. In addition, the improvement of ambient temperature will lead to the enhancement of chemical activity inside the battery, resulting in a lot of heat, which will in turn increase the ambient temperature. This vicious cycle will accelerate the life of batteries.
(2) regular charging and discharging. The UPS power supply system of floating charge voltage and discharge voltage, at the factory have been adjusted to the rated value, and the discharge current is increased with the increase of load, load regulation should be reasonable use, such as the use of computers and other electronic equipment control units. In general, the load should not exceed 60% of the rated load of UPS. In this range, the battery will not be overcharged.
UPS is connected with the municipal electricity for a long time. In the environment of high power supply and little blackouts, the battery will remain in the state of floating charging for a long time. It will decrease the activity of battery chemical energy and electric energy mutual transformation, accelerate the aging and shorten the service life. Therefore, the discharge time should be completely discharged every 2~3 months, and the discharge time can be determined according to the capacity and load size of the battery. After a full load discharge is completed, recharge the charge for 8 hours.
