How long is the service life of the UPS power lithium battery?

How long is the service life of the lithium battery of UPS power supply? Many people are curious about the service life of the rack-mounted uninterruptible power supply. This depends on the operating environment, protection and maintenance status, the feelings of the old UPS company, if the efficiency is low, the capacity is not enough, the operating environment is poor, such as high temperature, too much gray layer, wet, etc., will reduce the battery life of the UPS power supply. Inadequate protection and maintenance will shorten the joy of life. According to many years of operating experience of many UPS battery manufacturers, the actual service life of UPS battery packs installed on mainframes is generally 5-8 years, and the warranty period of many manufacturers is 3 years. Under normal circumstances, the service life of the UPS power supply can reach 8-10 years, and the service life of the lithium battery can reach more than 15 years. Regular maintenance makes the UPS quality good. For example, many local data centers in the United States have been in use for about 20 years, and rackUPSpower batteries have never been replaced. What are the factors that affect the battery life? 1. If the ambient temperature is too high, the battery will be overcharged; if the ambient temperature is too low, the battery will be undercharged, which will affect the battery life. Therefore, the ambient temperature is generally required to be around 25°C. 2. Depth of discharge The deeper the depth of discharge of the rack-type UPS power supply battery, the fewer the number of cycles that can be used, so deep discharge should be prevented during use. 3. Floating charge voltage If the floating charge voltage is too low, it will lead to insufficient charging, and irreversible sulfate alkalization of the negative electrode of the battery will occur. Excessive floating pressure will accelerate the loss of water and corrosion of the positive electrode plate. In order to prolong the service life of the rack-type UPS power supply battery, the floating charging pressure should be set reasonably. 4. In the current situation of unstable voltage and current, the internal structure of the gantry UPS power supply will be seriously damaged, and the service life of the power supply will be greatly shortened. 5. Charging time If the charging time is too long, the battery life will be reduced simply, and the positive and negative plates inside the battery will bend, and the active material surface plates will fall off. Therefore, the usable capacity battery of the UPS power supply will be reduced, thereby destroying the lithium battery. In general, if we use the battery of the rack-mounted UPS power supply, if you want to keep it in the best condition and use it for a long enough time, first of all, it is the impact of the environment. The temperature must be appropriate, too high or too low, and two Is to ensure safe voltage and current when charging, so that the power is the best state of charge.
