The importance of uninterruptible power supply, Kehua uninterruptible power supply purchase and UPS battery replacement guide

In today's era of deep integration of digitalization and industrialization, stable power supply is like the "lifeline" for the operation of society. From the continuous operation of smart devices in homes, to the stable development of core businesses, to the security of key areas such as hospitals and finance, any power outage may cause serious consequences. As the core equipment to deal with power abnormalities, the importance of uninterruptible power supply (UPS) has become increasingly prominent. As a well-known brand in the industry, Kehua's uninterruptible power supply products are highly favored in the Jiangsu market for their reliable performance and advanced technology. At the same time, UPS batteries serve as the core of energy storage, and their timely replacement is a key link to ensure the continuous and efficient operation of UPS. The following will give you a detailed introduction to the importance of uninterruptible power supply, the purchase methods of Kehua uninterruptible power supply in Jiangsu area, and the key points of UPS battery replacement.

1. The importance of uninterruptible power supply

(1) Protect equipment hardware security

Modern electronic equipment, such as computers, servers, precision instruments, etc., have extremely high requirements for power supply stability. Instantaneous fluctuations, sudden rises or drops in voltage may cause irreversible damage to the electronic components inside the device. For example, when the hard disk in the computer host is running at high speed, a sudden power outage may cause the magnetic head to collide with the disk, scratch the disk, and cause physical damage to the hard disk. ； Core components such as motherboards and CPUs in servers are also easily burned due to overvoltage or undervoltage during power abnormalities. UPS can monitor the mains power in real time, and when voltage abnormalities occur, it can quickly intervene to adjust and deliver stable power to the equipment. It is like putting on a layer of solid "protective armor" for the equipment, effectively extending the service life of the equipment and reducing hardware maintenance and replacement costs.

(2) Ensure data security and integrity

In the data-driven era, data is the core asset of enterprises and individuals. Whether it is an enterprise's customer information, financial data, experimental data from scientific research institutions, or patient records from medical institutions, once it is lost or damaged due to a power outage, it may cause immeasurable losses. Take e-commerce companies as an example. During the peak period of promotional activities, if there is a sudden power outage, a large amount of order data being processed may be lost, which not only affects customer experience, but may also lead to transaction disputes and damage corporate reputation. When the mains power is interrupted, the UPS can immediately switch to battery power mode to provide continuous power for the equipment, ensuring that users have sufficient time to save data and shut down the system normally, protecting data security and integrity and avoiding business stagnation and economic losses caused by data loss.

(3) Maintain the continuous operation of key businesses

In the financial industry, securities trading systems, bank core business systems, etc. cannot be interrupted for a moment, otherwise it will cause chaos in the financial market. This is especially true in the medical field. Medical equipment in hospital operating rooms, intensive care units and other places, such as ventilators, monitors, surgical lights, etc., once powered off, will directly threaten the safety of patients. The signal control system of transportation hubs and the signal transmitting equipment of communication base stations also rely on stable power to maintain operation. As a backup power supply, UPS can achieve seamless switching when the mains power fails, ensuring that these key businesses are not affected, ensuring the stability of social order, and protecting the safety of public life and property.

(4) Improve production efficiency and economic benefits

For industrial production enterprises, once the equipment on the production line is shut down due to a power outage, restarting and debugging often require a lot of time and labor costs. Frequent power outages may also lead to product scrapping, raw material waste, and increased production costs. Take an automobile manufacturing company as an example. If an automated production line is shut down for one hour due to a power outage, it may delay the production of dozens of cars and cause huge economic losses. Equipped with a UPS, it can avoid production interruptions caused by short-term power outages, maintain the continuity of the production process, improve production efficiency, and indirectly create significant economic benefits.

3. UPS battery replacement

(1) Determine the timing of battery replacement

1. Observe the appearance : The appearance of the UPS battery needs to be checked regularly on a daily basis. If the battery shell is found to be swollen or deformed, it may be due to an abnormal internal chemical reaction that produces too much gas, resulting in excessive pressure. At this time, the battery has suffered a serious failure and needs to be replaced immediately. If you see traces of leakage on the surface of the battery, or severe corrosion at the battery terminals, it indicates that the electrolyte inside the battery has leaked, its performance has dropped significantly, and it cannot be used normally. You should arrange for replacement as soon as possible.

2. Check battery performance : With the help of professional battery internal resistance tester and capacity tester, battery performance can be accurately judged. When a battery internal resistance tester is used to detect that the internal resistance of the battery increases significantly and exceeds the normal range, it means that the internal plates of the battery are aging, the active materials are reduced, the reaction efficiency of chemical substances is reduced, and the performance is severely degraded. Generally speaking, when the actual capacity of the battery measured by the capacity tester drops below 80% of the nominal capacity, its power storage capacity cannot meet the normal power supply needs of the UPS, and the battery should be replaced at this time.

3. Based on age : Commonly used lead-acid batteries are the main battery type of UPS, and their normal service life is about 3-5 years. Even if the appearance of the battery is normal and no obvious problems are found in performance testing, when it reaches or approaches its service life, there is a risk of sudden performance decline due to the gradual loss of its internal chemical substances. To prevent the UPS from failing to provide normal power supply at critical moments, it is recommended to replace the battery in time.

(2) Steps to replace the battery

1. Preparation : First, purchase a battery that is compatible with the original UPS, and carefully check the model and specifications of the new battery to ensure that the voltage, capacity, size and other parameters are consistent with the original battery. For example, if the original battery voltage is 12V and the capacity is 100Ah, the new battery must also have the same parameters, otherwise it will affect the normal operation of the UPS. At the same time, prepare replacement tools such as insulated gloves, insulated screwdrivers, multimeters, and torque wrenches. Before operation, be sure to turn off the UPS and disconnect the mains input and load to ensure safe operation.

2. Remove old battery : Wear insulating gloves, follow the battery connection sequence, first use an insulated screwdriver to carefully disconnect the negative connection wire of the battery pack, and then disconnect the positive connection wire. Be gentle to prevent the positive and negative terminals from short-circuiting. For battery packs with multiple cells connected in series, remove the connections from each cell in turn. During the removal process, use labels or markers to mark the battery connection sequence and positive and negative polarity directions to facilitate subsequent installation of new batteries. After removing the connecting cable, carefully take out the old battery and avoid collision or falling when transporting it.

3. Install new batteries : Place the new battery on the battery rack in the marked order and positive and negative polarity directions, and tighten the fixing screws with a screwdriver to ensure that the battery is installed securely. Then, connect the positive connecting wire first, then the negative connecting wire in the marked order, and use a torque wrench to tighten the screws according to the specified torque (usually 1.5 - 2.0N·m) to ensure a good connection and prevent poor contact from affecting battery performance and UPS operation. After the connection is completed, use a multimeter to measure the total voltage of the battery pack and compare it with the battery pack voltage required by the UPS to check whether the voltage is normal.

4. Restore UPS operation : After confirming that the new battery is installed and connected correctly, reconnect the mains input and load of the UPS, turn on the UPS, observe the operating status, and check whether the panel indicators are normal, such as whether the power indicator light is always on, whether the battery charging indicator flashes normally, etc. After the UPS has been running for a period of time, use a multimeter to check the battery voltage again to ensure that the battery is charging normally and that the UPS can supply power to the load equipment stably. If you find abnormal voltage or unstable equipment operation, shut down the UPS immediately and recheck the battery connection.

(3) Precautions when replacing the battery

1. Safety first : UPS batteries contain highly corrosive substances such as sulfuric acid and have a certain voltage. Safety regulations must be strictly followed during the entire replacement process. Wear protective equipment such as insulating gloves and protective glasses throughout the entire process, and always pay attention to prevent short circuits between the positive and negative poles during operation. If you accidentally come into contact with battery leakage, immediately rinse the contact area with plenty of water for 15 - 30 minutes, and seek medical attention as soon as possible to avoid serious injury.

2. Properly dispose of used batteries : Used UPS batteries are hazardous waste and will cause serious pollution to soil and water sources if discarded at will. In Jiangsu, you can contact local professional waste battery recycling organizations, such as environmental protection recycling companies in Nanjing, Suzhou and other places. They will provide door-to-door collection services and professionally process waste batteries. You can also call the local environmental protection department to inquire about nearby designated waste battery recycling points and properly send the waste batteries for recycling to ensure environmentally friendly disposal.

3. Avoid mixing old and new batteries : When replacing batteries, be sure to replace the entire set, and do not mix new batteries with old batteries. Because there are differences in performance, internal resistance and other parameters between old and new batteries, mixed use will cause the new batteries to overcharge or discharge, which will not only shorten the service life of the new batteries, but also affect the overall performance and power supply stability of the UPS, and may even cause safety hazards.
