Since many rooms are unattended, the uninterrupted power supply of the power supply is the prerequisite for computer room equipment to operate safely in unmanned states. The battery is a very important role in unmanned professional room as a spare DC power supply unit. The valve-controlled sealed lead battery is one of the lead storage battery, since it has good uniformity, self-discharge, no malfunction, no air, do not often add water maintenance, long service life, etc., widely used by communication industries As a reserve power supply. However, if you use improper or lack of correct maintenance, it often shortens its service life and scrapped in advance. The correct use of maintenance work can extend the life of the sealed lead-acid battery pack.The newly installed battery will tend to be uniform after a certain time floating. The reason is that the floating voltage of the battery and the battery-acid saturation have a large relationship. The battery is used in the initial period of use, the sulfate saturation is high, the gas composite efficiency is low, the gas precipitation speed and the composite speed are not equilibrated, so the floating voltage is not It is very stable, resulting in the initial expression of the monomer battery in the initial stage. After running one end, the saturation is slightly reduced, gradually tends to balance, and the battery floating voltage will tend to be uniform. Generally this transition time is 3-6 months. It can be seen that as long as there is a convergence trend of the floating charge of each unit cell in the same battery group, the new installation battery is too large (maximum and minimum exceeding 100mv) phenomenon, and the performance of the battery pack is also the performance of the battery pack. No effect. In addition, we can also use a method of repeating the battery pack after discharge, the internal reaction of the battery voltage reaches the balance as soon as possible to ensure the floating voltage is stable.
Sometimes the battery can be observed when the battery is used for a while, and most people may think that it is a leak. It can be seen that the battery is automatically opened when the battery is in the process of floating charging, and the safety valve valve cap will automatically open when the internal air pressure of the battery reaches the valve. The rate of the battery is relatively high, when the temperature is high in summer, the gas rate of the battery will speed up, and the internal acid solution is large for the short battery, which is large, and precipitation in gas At the same time, there will be a small amount of acid to precipitate with the gas. The acid solution with out is condensed into a small acid drop at the valve seat depression, and the liquid droplets will clip the acid along the wall, and finally overflow from the air outlet from the cover sheet. Spilled acid solution and air contact, generate white sulfate crystals, that is, the "white chip" phenomenon we see. In general, this phenomenon does not have a big impact on the performance of the battery, mainly affecting the appearance, as long as the white granulation is removed. However, if the white chrome is frequently occurring, it may cause blockage problems in the air outlet, and even corrode battery connectors, it is recommended to replace the safety valve or notify the manufacturer to solve.
Battery leakage failure is a more common phenomenon during battery usage, mainly three cases of trough leakage, pole leakage liquid, and safety valve, which are caused by poor battery self-manufacturing processes. If a collision occurs during the handling and installation, the battery housing will be broken, and the leakage is also available. The battery leakage fault recommendation notification manufacturer is solved. In addition, we should pay attention to the pseudo-leakage phenomenon of the valve body and pole column, the difference is that the fake leakage is caused by a white crystalline caused by a trace acid solution brought out from the sour or gas, and does not liquid Stay, and battery performance has no effect. We can also use acid alkalin quasi-test paper to determine if the battery is leaking.
In general, this problem is mainly caused by the following cases: the battery connection in the battery pack is loose or corroded, and the contact resistance is too large, and the voltage loss is severe during discharge. The ambient temperature is not guaranteed: When the temperature is too low, the internal reflection of the battery is slow and the capacity is lowered and the temperature is too high. The battery floating state is more serious, the battery has a certain water loss, battery acid solution is saturated Deceased, resulting in a decrease in the use of the battery life. The power supply is not guaranteed, the power failure is frequent, and the charging is insufficient. The battery often does not have sufficient electricity in time after discharging, and in this case, part of the active substances of the battery will fail, and the battery capacity is lowered. A backward battery appears in the battery pack, resulting in too fast in the discharge voltage, and seriously affecting the performance of the entire set of batteries.
