What are the precautions for charging the lead-acid battery of UPS power supply

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 early 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 cell batteries rise more slowly than other single cells, or even if the change is not clear, stop charging, find out the cause in time, eliminate the fault, or perform low-current charging alone to restore it to normal Then, recharge with other batteries. 3. During the entire charging process, it is necessary to measure the temperature of each single-cell UPS battery at any time, so as not to affect the battery performance due to excessive temperature. When the temperature rises to 45°C, the charging should be suspended. When the temperature drops below 35°C, continue charging. 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 is necessary to strictly follow the procedures and use utensils to operate. 6. When charging indoors, you should unscrew the filling hole cover 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, beware of explosions, and try to beware of harm to the human body. 8. Do not smoke or fire 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 according to regulations, 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. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
