Posted March 16, 20231 yr Need some help with UPS ME-1000-WPTU. Is there solution for the UPS, it does not matter what size batteries I put on, it only give me between 30 to 40 mins worth of power. I added 2 x100AH batteries to test and still only 35 mins. The timer is set to 999 max and still same issue. When you turn it on for a moment it will show 18h back up and then just jump to 30-40mins back up time (this is when I tested with 2x100ah batteries) Like its not calculating the back up correctly.
