Ways to increase the stability of UPS If you want to get full service from UPS, you have to keep an eye on some important things. Many users turn off the computer after working on the computer as well as keep the UPS-T from the power connection line. It should not be done on the mat. Since the UPS stores power from the main power line to its own battery, if it is disconnected from the main connection line, the UPS does not charge properly. Therefore, it cannot store electricity and as a result, it cannot supply electricity properly and for a long time. For this, after turning off the computer, the on-turn button of the UPS can be turned off, but the switch on the main power line cannot be turned off. This will keep UPST fully charged at all times and will enable it to provide better service for a long time.
