Myth 1: 'Maintenance-free lead-acid batteries' do not require regular maintenance The so-called "maintenance-free" means that compared with traditional open batteries, it does not require regular addition of electrolyte or distilled water, rather than regular inspection of its 'health status'. If these maintenance-free batteries are not checked regularly, they are very prone to deterioration and failure. If it is light, it will cause liquid leakage and corrosion, and internal short circuit, and if it is serious, it will cause local fire and cause a fire. Myth 2: To maintain the battery, you only need to monitor the voltage Due to cost factors, some engineers often use a multimeter to test the floating charge voltage of the battery. Currently, online systems on the market also use the battery voltage to monitor and evaluate the health status of the backup battery or energy storage battery. But the floating charge voltage can only reflect whether the charger is working normally, but not the health status of the battery. When the battery capacity drops, the floating charge voltage is likely to remain falsely high due to the control of the UPS charger. This is why in many cases the voltage of the UPS shows normal, but the battery pack loses power quickly after a power outage and cannot be discharged. So what items do you need to test during maintenance? How to choose the test frequency? The Institute of Electrical and Electronics Engineers' maintenance standard for valve-regulated lead-acid batteries (IEEEStd 1188™-2005) can provide a reference for you. In addition to the float voltage, the internal resistance of the battery, the temperature of the negative pole and the ripple voltage are all parameters that need to be paid attention to. The above are two major misunderstandings in battery maintenance.

The battery pack is an important part of the UPS system, and its cost is also high. Therefore, when the UPS system runs for a certain period of time and needs to be replaced to ensure the reliability of the UPS system, the user will always ask what is the standard for replacing the battery pack, and are there any relevant specifications and requirements? ? In fact, there is no mandatory requirement to replace the battery pack. The following are two reference indicators of battery life that have been edited and arranged for customers to refer to. 1. Floating charge life refers to the number of years that the battery can be used when the battery can be discharged at a standard temperature with continuous floating charge and discharge not less than 80% of the rated capacity. 2. The number of 80% deep cycle charge and discharge is the number of times the battery with full capacity is fully charged after being discharged to 80% of the rated capacity. According to relevant regulations, when the rated capacity of the battery pack is lower than 80% of one of the two cases, it is recommended to replace the battery pack. So how to judge the capacity of the battery pack? To judge the battery capacity, you can use a battery internal resistance tester to test the current internal resistance of the battery. When the internal resistance of the battery increases to 1.5 times the internal resistance of the factory, it means that the battery capacity has dropped below 80%, and it is recommended to replace the battery pack. The above is the edited and sorted UPS battery replacement standard. You can refer to this. Since there are too many industries and scenarios for UPS applications, with different standards and requirements, it can be flexibly referenced and implemented in different industries.

In small and medium UPS power supply, sealed lead-acid batteries are widely used. Proper battery maintenance is the key to extending UPS battery life. For this, this should be done:1.It is strictly forbidden to over-charge the battery pack of the UPS power supply. Overcurrent charging can easily cause the positive and negative plates inside the battery to bend, resulting in a decrease in the available capacity of the battery and damage to the battery.2.It is strictly forbidden to over-voltage charge the battery pack of the UPS power supply. Overvoltage charging will cause the water contained in the electrolyte in the battery to be electrolyzed into hydrogen and oxygen to escape, thereby shortening the battery life.3.It is strictly forbidden to over-discharge the battery pack of the UPS power supply. Over-discharge is easy to sulfate the surface of the inner plate of the battery, resulting in an increase in the internal resistance of the battery, and even the phenomenon of "reverse polarity" in individual batteries, causing permanent damage to the battery.Buy branded batteries from well-known and large companies. Batteries are generally provided by professional battery manufacturers. Different brands and manufacturers produce batteries of different quality and price. Well-known large enterprises have large scale, strong technology, good after-sales service and guaranteed battery quality. For example, Power Kingdom brand batteries are made of real lead, and the quality produced by large manufacturers is high. Your best choice.
