What are the ways to maintain UPS battery capacity?

UPS power supply manufacturers introduce UPS battery capacity maintenance methods. The amount of power discharged by the battery under specified conditions or the length of discharge time is called battery capacity, in Ah or Amin. The traditional method of judging UPS battery capacity is the same as the method of judging ordinary batteries. The entire battery pack is separated from the communication power system and connected to a resistance wire, discharged at a constant current rate of eight or ten hours, and then reaches a certain end of discharge voltage first. The discharge time and current of a single battery are used to calculate its capacity. 1. Frequently check whether the vent is unblocked during use to prevent the battery from deforming or bursting; UPS batteries should be kept away from heat sources and open flames, and ventilation should be maintained during charging and use to prevent burns and injury. The recommended ambient temperature ideally is 25C. 2. The UPS battery is connected to the mains for a long time. In an environment with high power supply quality and almost no mains blackout, the battery is in a floating charging state for a long time. The accumulation of time will reduce the activity of the battery's chemical energy and electric energy conversion, and accelerate the aging, Shorten the service life. Therefore, it should be completely discharged every 2-3 months, and the discharge time can be defined according to the capacity of the battery and the size of the load. 3. When charging the battery, the voltage should not be too high or too low. It is best to keep the standard charging voltage of 12V (within the range of 13.514.5V). 4. The battery cannot be left unused for a long time. If the battery is to be stored, it must be recharged once within 36 months; once the battery is not used for a long time, the battery will gradually vulcanize due to its self-discharge characteristics, which will reduce the battery capacity of the UPS power supply. , Even scrapped. 5. Frequently check whether the battery connection line is firm. All the live connectors must be in good contact to prevent sparks from causing the battery to explode; the oxides and sulfates appearing in the battery clip must be scraped off and coated with petroleum jelly to prevent re-corrosion. 6. When the ambient temperature of our battery decreases, the battery capacity will also decrease significantly with the decrease in temperature. First, the electrolyte is not easy to flow, and the chemical reaction speed of the active materials at the two electrodes will slow down. The second is that the impedance of the electrolyte increases, and the battery voltage drops, and the battery's 10HR capacity will also decrease as the battery temperature drops.
