Factors affecting the service life of lead-acid batteries: ⒈Temperature temperature has a great influence on lead-acid batteries. Too high or too low will lead to a decrease in battery service life, especially high temperature, which has a significant impact on battery life. Generally speaking, the ambient temperature should be controlled at about 25°C. ⒉Depth of discharge The depth of discharge has a great influence on the service life of lead-acid batteries. The greater the depth of discharge of the battery, the less the number of cycles, so you should try to prevent deep discharge during use. Discharge of small current is easy to cause deep discharge. ⒊Float charging voltage Since the UPS battery is a standby mode of operation, the mains is in a charging state under normal conditions, and it will only be discharged when the power fails. In order to prolong the service life of lead-acid batteries, the float voltage must be set reasonably. If the float voltage is too low, it will lead to insufficient charging and irreversible sulfation of the negative electrode of the battery; if the float voltage is too high, it will accelerate the loss of water and the corrosion of the positive plate. Factors that affect the cycle life of UPS lithium battery packs: 1. Material types The choice of materials is the first element that affects the performance of lithium battery packs. The cycle performance of the material is poor. On the one hand, it may be that the crystal structure changes too fast during the cycle to continue lithium insertion and removal. On the other hand, it may be that the active material and the corresponding electrolyte cannot form a dense and uniform SEI film, which causes the active material. Premature side reactions with the electrolyte will cause the electrolyte to be consumed too quickly and affect the circulation. 2. Positive and negative electrode compaction The positive and negative electrode compaction is too high, although it can increase the energy density of the lithium battery UPS, it will also reduce the cycle performance of the material to a certain extent. From a theoretical analysis, the greater the compaction, the greater the structural damage to the material. 3. Excessive moisture will cause side reactions between the UPS lithium battery pack and the positive and negative active materials, destroy its structure and affect circulation. At the same time, excessive moisture is not conducive to the formation of SEI film. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
