Introduce the precautions and years of UPS battery use

Precautions for the use of UPS batteries 1. The parameters set in the UPS host cannot be changed at will during use. Especially the parameters of UPS battery packs will directly affect the service life. As the ambient temperature changes, the float voltage must be adjusted accordingly. Generally, 25°C is used as the standard. When the ambient temperature rises or drops by 1°C, the float voltage should be increased by 18mV. 2. When the UPS power storage battery system is self-powered, it is necessary to prevent the UPS power supply from starting with a load, turn off the loads first, and then turn on the load after the UPS power supply system starts. There will be an impact on the battery when the load is supplied instantly, and the impact current of multiple loads and the required power supply current will constitute an instantaneous overload of the UPS power supply. 3. The working condition of floating charging is still charging, discharging and overhauling, and it is necessary to ensure that the voltage and current comply with the regulations. Excessive voltage or current may cause thermal runaway of the UPS battery. Too small voltage and current may cause battery power loss and affect the service life of the UPS battery. Fourth, the UPS power supply system should prevent the random addition of high-power additional equipment during use, and it is not allowed to operate for a long time under full load. The nature of the work determines that the UPS power system works in an uninterrupted state, and a high-power load is added, which will damage the converter in severe cases. 5. It is necessary to prevent high-current charging and discharging of UPS batteries. Although it can withstand large currents during charging, it should be prevented as much as possible in actual operation, otherwise it will cause the battery plate to swell and deform, and the active material of the plate will fall off, and the internal resistance of the battery will increase. The higher the temperature rise, the more serious the capacity will be reduced . 6. Prevent short circuit or deep discharge of UPS battery pack. The cycle life of the battery is related to the depth of discharge. The deeper the depth of discharge, the shorter the cycle life. In the capacity test or discharge maintenance, the discharge can reach 30% to 50% of the capacity. UPS battery service life The service life of the UPS host is generally 5-8, and the warranty of many manufacturers is 3 years. The price of the battery is very high, and it is much higher than the cost of the generator for ordinary applications. Therefore, in many cases, the battery is used for transitional buffering purposes. In addition, the UPS battery is the same as the car battery, and it cannot be easily discharged, which damages the battery life, and the charging speed of the UPS is relatively slow. It usually takes about 72 hours to fully charge with the photoelectric. Taking into account factors such as load conditions, use environment, service life and cost, in order to ensure the reliable, stable and safe operation of the system, it is generally recommended to replace the UPS battery every 5 years, depending on the actual situation. The normal service life of the UPS battery pack is generally 3-5 years, and the battery is generally guaranteed for three years. A better quality battery can be used for about 5-8 years. The discharge time of the battery pack should be calculated according to the power of the UPS power load and the capacity of the battery pack. The types of UPS batteries can generally be divided into lead-acid batteries, lead-acid maintenance-free batteries and nickel-cadmium batteries. Taking into account factors such as load conditions, use environment, service life and cost, in order to ensure the reliable, stable and safe operation of the system, the general UPS The battery is recommended to be replaced once every 5 years, depending on the actual situation.
