The hot summer is coming, with the increase of data center capacity, expansion of scale and introduction of new equipment and technology，servers and key devices are threatened by high temperature all the time, and the difficulty of data center operation and maintenance is also increasing, resulting in many problems.

The critical power supply system in IT room is required to run continuously 24 hours a year for reliable, stable, and efficient operation.

VRLA battery is called \"maintenance-free\", but the market battery manufacturers, mixed, uneven quality, and in actual use, due to the deterioration of the battery itself, the capacity of the battery is also declining, especially in the actual use of a battery performanhe probability of an accident is greatly increasedce deterioration will drag down the performance of the whole battery, once the power failure, T

Backup Power System problems topped the list of factors causing outages in data centers，And it continues to rise, reaching 44% in 2022.The survey also revealed that the biggest cause of power system problems was UPS failures. Therefore, the security and reliability of UPS is particularly critical to the continuous operation of data centers.

UPS battery faults are the primary cause of data center downtime. Among UPS faults, lead-acid batteries are the main cause, with a probability of 50%. Proper use and maintenance of batteries is one of the key factors to extend battery life and reduce the total failure rate of UPS power supply.

Data room battery hundreds of thousands, human inspection of professional and technical requirements are relatively high, battery number base is large. Part of the detection means in the detection process can not meet the corresponding detection requirements, so with the help of professional management means, to solve the human can not reach the new height, battery online monitoring system is a good solution.
