How to use lithium battery UPS correctly?

How to use lithium battery UPS correctly? 1. The ambient temperature of the UPS must be kept at a suitable temperature for the UPS battery to work normally. For general batteries, the temperature of the environment should be kept between 20-25 degrees Celsius. The lithium battery UPS can work normally at -20-60 degrees Celsius, without air conditioning, reducing equipment installation costs, maintenance costs, and electricity costs. 2. Regular inspections should be carried out. Periodically check the terminal voltage and internal resistance of each unit UPS battery. The above-mentioned imbalance due to the changes in the characteristics of each unit battery over time cannot be eliminated by the internal charging circuit of the lithium battery UPS power supply. Therefore, for battery packs with obvious imbalance in this characteristic, if offline equalization is not taken in time, the imbalance will become more and more serious. 3. Under certain conditions, re-float the lithium battery of the UPS power supply and stop for more than 10 days. Before restarting, start the UPS power supply without load to re-float the lithium battery for 10-12h using the charging circuit in the machine. Run with load after the above. The UPS power supply is in a floating charge state for a long time without a discharge process, which is equivalent to being in a storage standby state. If this state lasts for too long, causing the lithium battery to become invalid due to long storage, it is mainly manifested in the increase of the internal resistance of the battery, which can reach a few in severe cases.
