< : : : (>Necessary maintenance of power supply batteries is indispensable.
< : : : (>The necessity of uninterruptible power supply battery maintenance. Currently, maintenance-free sealed lead-acid is widely used in small and medium-sized power supplies. Batteries account for more than % of the total cost of power supply. According to data, China's production technology is relatively mature, and more than % of power failures are related to batteries. At present, my country's power supply situation is becoming increasingly perfect, especially in cities, where long-term power outages rarely occur. , and many important departments use dual-circuit power supply and diesel generators to ensure the supply of electricity, which makes people relax the daily maintenance of uninterruptible power supply batteries. Most batteries do not know their own systems at all due to lack of effective maintenance. The health of the battery causes the user to be unable to work according to the designed delay in the event of a long power outage. On the other hand, the user's load is constantly increasing, and the power density is becoming more and more concentrated, so the load is also increasing accordingly, and the battery delay The problem of not enough will become more prominent.
< : : : (> The failure of the uninterruptible power supply battery is mainly manifested by insufficient terminal voltage, insufficient capacity or the instantaneous discharge current does not meet the load starting requirements. When using the uninterruptible power supply, In the process of installing the system, people often one-sidedly believe that the battery is maintenance-free and do not pay attention to it. It can be seen that strengthening the correct use and maintenance of the battery is increasingly important to extend the service life of the battery and reduce the system failure rate. meaning
