The first point: Regularly check the voltage and internal resistance of a single battery, in the 12V battery, if it is found that the end voltage difference between a single battery is expected to exceed 0.48V or the internal resistance value is high, it should be equalized to a single battery. To restore the internal resistance of the battery and eliminate end voltage between a single battery.

The charging voltage is 13.8 ~ 14.4V when charging.

Most batteries that are equalized to charge can return their internal resistance to normal usage. During the operation, the charger of the itself cannot adjust the voltage of a single battery, so the unbearable level will become more and more serious if the single battery is charged separately. Second: Prevent Most of the UPSs from overcharged, all UPSs are equilibrated and floating, but when the UPS charger failure results in a floating charge voltage exceeding the charging voltage specified by the battery, or the UPS charger has technical defects.

When the voltage is far exceeds the power-up voltage value specified in the battery, long-term charging will cause the battery to be damaged in advance. Therefore, the charging voltage of the UPS should be measured before the UPS is in use, determine whether the voltage satisfies the charging voltage of the battery. Third point: Regularly discharge the battery for the battery for a long time in the floating state without letting electricity, the longer the time, the shorter the battery life, the shorter life, it is important to increase the internal resistance of the battery, and cannot be repaired.

It is therefore recommended that the user performs moderate discharge of the battery at least half a year, so that the UPS power supply works in the state of battery power, this discharge state is not too long, generally discharging to the battery capacity of 50%. Quaternary: Preventing the battery depth discharge electricity, his service life is closely related to it is discharged. The lighter the load of the UPS power supply, the larger the battery of the battery and its rated capacity, and in this case, when the UPS power supply is too low because the battery voltage is too low, the battery discharge is referred to as depth discharge, That is, small current long-time discharge.

The actual process should try to prevent depth discharge, it is recommended that the battery supply time should not exceed 8 hours. 5.:00 guaranteed ambient temperature and air circulation battery available capacity closely related to the ambient temperature, in general, the performance parameters of the battery are calibrated at room temperature at 25 ¡ã C.

Therefore, when the temperature is below 20 ¡ã C, the capacity of the battery will decrease as the temperature is lowered, at -20 ¡ã C, the battery can only reach the nominal capacity of about 60%. When the ambient temperature is above 25 ¡ã C, the capacity of which is available is slightly added, but the battery life will be shortened as the temperature increases, and the battery will be thermal out of control while more than 60 ¡ã C. At the same time, the lead-acid battery uses or overcharges in a high temperature environment, and there will be hydrogen spillover in the case of over-discharge, such as the ventilation of the room, which causes fire or explosion.

Therefore, the room placed in the lead-acid battery except for the temperature between 20 and 30 ¡ã C, but also to install a new wind ventilator to ensure air circulation. Sixth point: Adopting the advanced battery monitoring protection system through the battery monitoring protection system, the charging voltage, charge and discharge current, internal resistance, and temperature of each storage battery can be real-time monitoring. When the system detects an abnormality of the parameter of a battery, the system issues alarm; when the system detects that a set of batteries is in a dangerous emergency state, the connection of the battery and the UPS host can be cut off to prevent unsafe accidents.
