UPS uninterruptible power supply battery charging and discharging interval time

Some common knowledge to pay attention to in the maintenance of UPS uninterruptible power supply batteries: If the internal batteries of the UPS power supply are idle for a long time or left in a floating state without discharging for a long time, it will cause a large amount of lead sulfate in the battery to adsorb onto the cathode surface of the battery, forming the so-called "sulfation" of the battery cathode plate. So, the battery should be charged and discharged every 3-4 months, with a discharge rate of 20% -30%, but remember not to discharge deeply.
