With the development of social technology, in order to prevent losses and impacts caused by sudden power outages, UPS batteries have gradually emerged in the power market after repeated research. This article analyzes and discusses the common problems of early performance decline, charging obstruction, short circuit, battery leakage, expansion and deformation of UPS batteries, and combines them with the actual situation to make corresponding solutions.

Keywords: UPS; Battery; Frequently Asked Questions

Introduction: UPS batteries, also known as uninterrupted power supply stations, can quickly adjust to another operating condition in the event of a sudden power outage and provide the necessary power for the operation of electronic information equipment. However, UPS batteries themselves are prone to varying degrees of problems or issues due to external disturbances. It is necessary to optimize them comprehensively according to specific treatment methods and fully utilize the actual effectiveness of UPS.

1、 Early failure

For UPS batteries, there are very clear definitions and requirements for storage conditions. Once the storage temperature or other related factors show abnormal fluctuations, it is highly likely to affect the battery's electrical power. Early failure of UPS batteries refers to a significant decrease in power capacity and overall operational performance during the initial or specified usage period, which severely affects subsequent use and the useful operation of corresponding equipment. After repeated verification, it was found that there are two reasons for the early failure of UPS batteries. The first reason is that batteries exhibiting early failure symptoms will continuously increase their internal voltage under stable and balanced power supply. The failed batteries are now overcharged while a group of UPS batteries is not fully charged, and their internal temperature far exceeds the normal temperature range of UPS batteries. In this situation, the liquid inside the UPS battery continues to rise due to the increase in temperature, leading to a significant acceleration in the differentiation and flow rate of the electrolyte. The overall voltage of the UPS battery rises to a certain peak, reducing the current supply and forcing the charging time to be extended. Finally, the service life of the UPS battery is severely affected and shortened, resulting in early failure. The second point is that short circuits often occur inside UPS batteries that have already failed. Due to abnormal voltage changes, the charging time of UPS batteries varies significantly. During the process of releasing power, the failed batteries themselves lack sufficient stored power, causing the internal voltage to quickly to zero and leading to early failure of the batteries.

Generally speaking, after the early failure of UPS batteries, their internal resistance will significantly increase, showing symptoms such as voltage rise and insufficient power capacity. The primary way to deal with this problem is to identify and replace the expired batteries inside, and then prevent any impact on other healthy batteries. The entire set of UPS batteries that are about to be put into use can be connected to the power detection system for deep discharge testing. When individual batteries with significantly abnormal voltage data are found, they need to be removed and replaced to effectively improve the actual function and operating power of UPS batteries [1].

2、 Charging problem

During the operation of some UPS batteries, they may occasionally become unable to charge, resulting in delayed power supply during power outages and significant economic losses. The reasons for the charging problems of UPS batteries need to be addressed from the aspects of overall line connection, smoothness of charging lines, numerical stability of electrolyte liquids, and daily protection of battery plates. Combined with the actual situation of UPS, the root cause of charging obstruction should be identified.

Generally speaking, in order to determine the root cause of UPS battery charging problems, it is necessary to investigate and inspect the problem points, identify the source of the problem, and implement corresponding solutions. When the UPS battery shows high-intensity voltage but no significant current influx, the problem can be attributed to internal issues with the battery, most likely due to interrupted or damaged connections. Professional technicians are needed to repair and handle the issue in order to further identify and address it. When the UPS battery detects no abnormal voltage, it can be left to stand for a period of time after being fully charged. If the internal voltage is found to be lower than the normal voltage standard of the battery, it can be determined that the inability to charge is due to a short circuit problem in the UPS battery, which needs to be addressed. In addition, for batteries that have not been used or have been used for a short period of time, once a charging problem occurs, it can be basically confirmed that it is caused by severe collisions or falls during normal use. Through professional technical personnel's disassembly and reorganization, the charging problem can be well handled. In addition, on UPS batteries that have not been used for a long time or have been used for too long, there may be a situation where they cannot be charged. Therefore, it is necessary to immediately check the sediment at the bottom of the battery. If the sediment is too small, it indicates that the purity of the electrolyte liquid is not good, which can cause a short circuit problem in the power line. On the contrary, it indicates that the electrode plate cannot effectively perform its function and needs to be replaced with corresponding protective measures.

3、 Internal short circuit

The short circuit problem of UPS batteries can be said to be one of the most common problems. The primary reason is that there are a large number of deposits on the internal plates that cannot be differentiated. Perhaps due to external forces, the plates are deformed, and the positive and negative plates are in direct contact, resulting in the inability of current to flow and operate. The best way to deal with short circuit problems is to disassemble the exterior of the battery, investigate the sediment condition at the bottom of the battery, and promptly protect and clean it. Regarding the possibility of displacement or deformation of the electrode plates, it is necessary to immediately cut off the power supply to prevent damage to the internal circuit caused by short circuits. Then, replace or reset the electrode plates, and effectively address the short circuit issue of the UPS battery.

4、 Battery leakage

In the process of using UPS batteries, the problem of leakage can be said to be endless, not only seriously affecting the power of the battery, but also causing impact or damage to the surrounding ecological environment, resulting in severe damage to ecological benefits. Generally speaking, the leakage problem of batteries is often caused by inadequate protective measures during transportation or handling, resulting in severe collisions and compromised sealing, causing the electrolyte of the battery to leak. The primary issue lies more in the quality level of UPS battery production. Therefore, in order to better optimize battery leakage problems, we can improve supervision during the production and processing process, do a good job in material screening, conduct comprehensive inspection and treatment of the appearance and sealing degree of the battery, fully and uniformly distribute the overall amount of electrolyte, so that it can always be maintained within the safe threshold range, effectively preventing the occurrence and occurrence of UPS battery leakage problems. In addition, when significant leakage is observed in the pole, inert gas can be used to weld and seal it, extend the terminal length of the pole, and perform adhesive sealing operations to improve the overall sealing of the pole.

5、 Deformed bulge

Generally speaking, the problem of deformation and bulging of batteries is often due to a sudden increase in internal pressure in a short period of time, which may cause blockage due to poor gas flow or other factors. This leads to the production of flammable and explosive gases in the process of continuously absorbing electricity from the battery. If it is not dealt with in a timely manner and turned a blind eye, it will lead to an increasing internal pressure, causing the battery casing to swell and crack, severely damaging the overall service life of the battery. Moreover, in some batteries with poor performance or raw materials, if effective gas differentiation and treatment are not carried out in a timely manner, severe expansion and deformation problems may occur during the use of the battery. This not only affects the performance of the battery itself, but also threatens the safety of individuals' lives and property. Therefore, it is necessary to pay attention to and focus on this issue. After the UPS battery showed deformation and bulging, the relevant operators immediately stopped power transmission to assist in reducing the gas accumulation inside, easing the pressure problem caused by the battery surge, and following the relevant procedures to dredge it, effectively preventing safety accidents and extending the service life of the UPS battery.
