Regular charging and discharging of the battery is a very important job to maintain the battery. If your UPS has a battery detection function, you can perform this function regularly. If you do not have this function, you can remove the plug of the UPS power input, imitate the mains interruption, and then investigate whether the battery discharge time is enough. If lacking, the battery can be replaced to maintain sufficient discharge time when the power supply is discontinued to facilitate file storage and complete shutdown of the system.

UPS Uninterruptible power supply Vida battery It is recommended to use Vida battery or other brands of high-quality maintenance-free batteries. Users must not choose bad ups unbroken power supply battery because of cheap will have self-discharge phenomenon (SELF-D1SCHARGE), if not placed for a long time, it will cause energy loss, so it needs to be regularly charged and discharged.

Engineers can determine the quality of the battery by measuring the open circuit voltage, taking the 12V battery as an example, if the open circuit voltage is higher than 12.5V, it indicates that the battery energy storage is more than 80%, if the open circuit voltage is lower than 12.5V, it should be immediately made up for charging, if the open circuit voltage is lower than 12V, it indicates that the battery storage energy is less than 20%. The battery is in danger of exhaustion.

Due to the selection of absorption electrolytic liquid system, no gas will occur during normal use, but if the user uses improperly, forming a battery overcharge, gas will occur, at the moment the internal pressure of the battery will increase, the pressure valve on the battery will be opened, and the severe will make the battery bulge, deformation, leakage or even rupture. These phenomena can be distinguished from the appearance, if the above situation is found, the battery should be replaced immediately.
