UPS is a very useful device. It is required in responsible electrical systems where power failure is not allowed. The batteries in the UPS must be replaced from time to time. This is due to the wear of the cells. I replace the batteries in my UPS when the device prompts you to replace the batteries. There are 2 12V 9Ah gel batteries in my device. Remember that the replacement of batteries should be performed by a person who is authorized to do so. Despite removing the plug from the socket, the UPS can still generate dangerous voltage from the battery. More in the video.
