    Tips: Use and maintenance of UPS
    1. Maintain the appropriate ambient temperature
    The important factors affecting the life service of battery is ambient temperature. Although the increase in temperature increases the discharge capacity of the battery, the life service of the battery is greatly shortened.
    2. Regular charging and discharging
    The battery will remain in the floating charge environment for a long time if it is in the use environment of high electric quality and few power failures, thus causing the decrease of the activity of mutual transformation of battery chemical energy and electric energy, acceleration of its aging and shortening of its life service. Therefore, it should be discharged completely every 2-3 months. The discharging time depends on the battery capacity and the load. After the discharging of a full load, the battery should be charged for at 8 hours as provided.
    3. Communication function
    Most large and medium UPS have operational performance with microcomputer communication and program control.The corresponding software is installed on the microcomputer, which is connected to UPS by series or parallel port. You can use microcomputer to communicate with UPS during the operation of this procedure.Generally, it has the functions of information inquiry, parameter setting, timing setting, automatic shutdown and alarm. It is convenient for the use management of UPS power and battery through these intelligent operations.
    4. Timely replacement of waste or bad battery
    In the continuous operation of UPS, due to the difference in performance and quality, it is inevitable that the performance of individual batteries will decline, and the storage capacity will not meet the requirements.When a battery or some batteries are damaged in the battery pack, the maintenance staff should check and test each battery to remove the damaged battery. The same type battery of the same manufacturer should be replaced. The acid battery, sealing the battery, or batteries of different specifications are not allowed to be used together.
