How long can the service life of UPS uninterruptible power supply reach? This depends on the operating environment, maintenance and maintenance conditions, and the company’s attitude towards the old UPS. Inefficient, insufficient capacity, poor operating environment, etc. will shorten the life of the UPS, and if the maintenance and maintenance are not in place, it will also shorten the UPS. Life. In order to improve the quality of UPS power supply work in the computer room, strengthen daily management work, and ensure that the UPS uninterruptible power supply equipment in the computer room is always in a good environment and the equipment operates safely and stably, daily maintenance of the UPS power supply must be done. For example, the fan and capacitor must be at 5~ Replace within 7 years. If none of the above is a problem, the UPS can be used forever. The service life of lead-acid batteries has a lot to do with battery quality, environmental humidity, charge and discharge times, and charge and discharge procedures. The ideal constant humidity environment is 20-25 degrees. , Charging and discharging are not frequent (no more than two or three times a month), the battery is regularly maintained, and the battery and UPS can be used for more than 15 years if the quality of the battery and UPS is good. Of course, the remaining capacity will be reduced as the use time is longer. Normally, the service life of a UPS power supply can generally reach 8-10 years, and a properly maintained UPS power supply can be used for more than 15 years, which has a lot to do with the core component battery of the power supply. Below we Let's introduce the maintenance of common UPS power supply and industrial UPS power supply.

UPS power supply maintenance

Uninterruptible power supply is a constant voltage and constant frequency uninterruptible power supply that contains energy storage devices and uses inverters as the main component. It is mainly used to provide uninterrupted power supply to a single computer, computer network system or other power electronic equipment.

(1) The perfect maintenance condition is: UPS room should be air-conditioned and anti-static floor room, with good lightning protection effect, dust, moisture, and sun protection. The input voltage is best within the design range, and the most reasonable load range is 30%-60%. Full load and overload use will affect the life of the UPS. Maintain at least once a year.

(2) Timely replacement of used/bad batteries: The number of batteries equipped with large and medium-sized UPS power supplies ranges from 3 to 80, or even more. These single batteries form a battery pack through circuit connection to meet the needs of UPS DC power supply. In the continuous operation and use of UPS, due to the difference in performance and quality, it is inevitable that individual batteries will be damaged due to performance degradation and insufficient power storage capacity. When one/some batteries in the battery pack are damaged, the maintenance personnel should inspect and test each battery to exclude the damaged battery. When replacing a new battery, you should try to buy the same type of battery from the same manufacturer. It is forbidden to mix acid-proof batteries, sealed batteries, and batteries of different specifications.

(3) Maintain a suitable ambient temperature: The important factor affecting the battery life is the ambient temperature. Although the increase in temperature improves the discharge capacity of the battery, the price paid is that the life of the battery is greatly shortened. According to tests, once the ambient temperature exceeds 25°C, the battery life will be shortened by half for every 10°C increase. If the specified environmental requirements are not met, the life span will vary greatly. In addition, the increase of the ambient temperature will lead to the enhancement of the internal chemical activity of the battery, thereby generating a large amount of heat energy, which in turn will promote the increase of the ambient temperature. This vicious circle will accelerate the shortening of the battery life.

(4) Periodic charging and discharging: The float voltage and discharge voltage in the UPS power supply have been adjusted to the rated value at the factory, and the discharge current increases with the increase of the load. The load should be adjusted reasonably during use . Generally, the load should not exceed 60% of the UPS rated load. Within this range, the battery discharge current will not be over-discharged. Because UPS is connected to the mains for a long time, in an environment with high power supply quality and few mains blackouts, the battery will be in a floating charge state for a long time, which will cause the battery's chemical energy and electric energy to convert between the activity and accelerate the aging And shorten the service life. Therefore, it should be fully discharged every 2-3 months, and the discharge time can be determined according to the capacity and load of the battery. After a full-load discharge is completed, charge it for more than 8 hours as required.
