First, maintaining a suitable ambient temperature usually, factors affecting the life of the UPS battery life is ambient temperature. General ambient temperature required by general battery packages is between 20-25 ° C. Although the battery used in the current UPS power supply is generally maintenance-free sealed lead-acid batteries, the design life is generally 5 years, which can reach in the environment requested by the battery.

Without the prescribed environmental requirements, the length of life is very different. In addition, the ambient temperature increases, speeds up the life of the UPS battery. Second, the floating voltage and discharge voltage in the regular charging discharge UPS power supply, all debugged to the rated value during the factory, and the size of the discharge current increases with the increase of the load, and should be reasonably adjusted reasonably.

For example, the number of applications such as electronic devices such as microcomputer. Under normal circumstances, the load should not exceed 60% of the UPS rated load. Within this range, the discharge current of the UPS battery will not excessive discharge.

UPS is connected to the market due to long-term power supply, and the battery will have a long-term power supply in a long time, and the battery will result in a long time to reduce the activity of battery chemistry and electrical energy to reduce the activity, accelerated aging. Shorten service life. Therefore, it is generally discharged once every 2-3 months, and the discharge time can be determined according to the capacity of the battery and the load size.

After the full load is complete, it will charge more than 8 hours according to the regulations. Third, timely replacement of waste / bad batteries Currently, the number of batteries equipped with large and medium-sized UPS power supplies, from 3 to 96 不, even more. These single batteries constitute a battery pack through a circuit connection to meet the UPS DC power.

In the continued operational use of UPS, due to performance and quality, individual battery performance has decreased, and the storage capacity is not required to be damaged. When a / some batteries in the battery pack occurs, the maintenance personnel should check the detection of each battery, exclude damaged batteries. When replacing new batteries, you should strive to purchase a battery with a model of the same model, prohibiting an anticipagate battery and a sealed battery, different specifications of UPS batteries.

IV. Using the high peak of the power supply to charge the battery to charge the utilization of the UPS battery for a long time in the long-term power supply or frequently-stopped power, it should be prematurely damaged for a long-term charging, which should ensure that the battery should be discharged. After that, there is enough charging time.

When the battery is depressed, it is more than 90% of the rated capacity to at least 10 to 12 h. 5. UPS power should not be fully loaded using the UPS battery should pay attention to the parameters of the UPS.

The various UPS power supplies should not be fully loaded. It should retain more than 20% of the power margin, and the load control is 40% of the UPS rated output power ~ 60%. .
