Usually, the battery in the machine room is not properly handled after the deterioration of a battery, and the battery deteriorates sharply, resulting in rupture and fire, Because the battery is in series or parallel in the application, a battery fire combustion, if found not in time, it will spread instantly, resulting in fire。

The service life of the UPS uninterruptible power supply manufacturer is mostly 8-10 years. The actual service life of the UPS power supply is often closely related to the power grid environment, the working room environment, and the load of equipment power。Excessive overload, poor operating environment, high temperature, and too much dust will greatly shorten the service life of the UPS uninterruptible power supply。

The use of UPS power supply must pay attention to daily maintenance and maintenance, in order to give full play to its role and prolong its service life. The following is a brief introduction to the maintenance method of UPS uninterruptible power supply。

Electricity is an indispensable thing for us. Because the power supply pressure is too large or the current is unstable, in order to ensure uninterrupted power supply, more and more enterprises and individuals choose uninterruptible power supply, so what should be considered when choosing a UPS power supply for the first time ？

Battery Internal resistance test is currently internationally recognized as the most effective and convenient performance parameter for battery measurement. It can reflect the performance indicators such as the deterioration degree and capacity status of the battery.

Due to problems in production process, transportation and installation, daily maintenance, etc，many batteries only have half the life of the manufacturer\'s design life, and some batteries fail even after 1 or 2 years，Correct inspection and maintenance is the root of the problem。
