What should I pay attention to when charging UPS battery?

Precautions for UPS battery charging: 1. Strictly follow the operating procedures. 2. During the charging process, check and record the electrolyte density and terminal voltage of each single-cell UPS battery in time. In the initial and middle stages of charging, check and record once every 2h; when approaching the end of charging, check and record once every 1h. If it is found that the terminal voltage and electrolyte density of individual single cells increase more slowly than other single cells, or even if the change is not obvious, stop charging, find out the cause in time, eliminate the fault, or perform low-current charging alone to restore normal Then, recharge with other batteries. 3. During the entire charging process, the temperature of each single-cell UPS power battery must be measured at any time to avoid excessive temperature affecting the battery performance. When the temperature rises to 45°C, the charging should be suspended, and the charging should be continued when the temperature drops below 35°C. Air cooling or water cooling can also be used to cool down. 4. The initial charging work should be continued, and should not be interrupted for a long time. 5. When preparing and pouring the electrolyte, it must be operated strictly in accordance with the regulations and using utensils. 6. When charging indoors, the filling hole cover should be unscrewed so that hydrogen and oxygen can escape smoothly to avoid accidents. 7. Ventilation equipment should be installed in the charging room. During the charging process, the ventilation equipment should work continuously to discharge harmful gases, prevent explosions, and try to prevent harm to the human body. 8. Smoke and fire should be strictly prohibited in the charging room. 9. The charging equipment and the battery to be charged should not be placed in the same room. When charging, connect the battery to be charged as required, and then turn on the power switch. When stopping charging, turn off the power switch first, and then remove the charged battery. The wire connection must be reliable and prevent sparks from appearing. 10. The charging room should always be equipped with tap water, 10% soda water or 10% ammonia solution.
