Do you know the maintenance method of UPS power battery group?

UPS power installation process of the main things in medium and small UPS power supply, the widely used is the so-called no maintenance sealed lead-acid battery, its price is more expensive, generally about UPS power about 1/3 to 1/2 of the total production cost. At the same time, we also found that due to the failure of UPS power storage batteries, the power supply cannot work properly and also has a large proportion. It can be seen that the correct maintenance of the battery group is the key to prolong the service life of the UPS battery group. To this end, it should:

1) it is strictly prohibited to the superior than UPS power battery charging current, because of the over current charge cause inside the battery positive and negative plate bending, active substance on the surface of the plate fall off, cause the loss of battery capacity is available for use, so that damage to the battery.

2) it is strictly prohibited to UPS power battery charged groups of overvoltage, because overvoltage charge will cause the battery electrolyte contained in the water by electrolysis and escape into hydrogen and oxygen, so as to shorten the service life of the battery.

3) prohibit excessive battery discharge of UPS power supply, easy to make because of excessive discharge of battery internal sulfate on the surface of the plate, as a result, lead to the battery internal resistance increases, even make the individual battery produces "antipole" phenomenon, batteries, permanent damage.

4) for UPS power sit idle for a long time, in order to ensure the battery has good charge and discharge characteristics, before using the reboot, had better not add load first, let the superior than UPS power use machines to float charging battery charging circuit of 10 ~ 15 hours later; For a UPS power that works in a back-up state for a long time, it usually works at least 2 to 5 minutes every other month for the inverter state.

The design and production process of the battery determine the inherent reliability of the battery group, and the use and maintenance of the battery group is the basis for ensuring the reliability of the battery group. According to the UPS power maintenance work, the statistic concludes that for the backup UPS power supply, the failure of the accumulator is more than 50% of the total fault. For on-line UPS, because of its reasonable circuit design, especially with the development of science and technology, most of them adopt integrated, modular, intelligent UPS power supply, and the configuration of reserve capacity is big, so little fault caused by the power supply and compared by the battery caused by failure to rise to more than 60%.

It can be seen that proper use and maintenance of battery is the key factor to prolong battery life and reduce the failure rate of UPS. "In a nutshell, the battery has three characteristics: large scale, high cost and high consumability. What you can do is try to extend the life of the battery, and in fact increase the availability of the data center.
