UPS won’t power up

Anonymous user · ‎2021-07-29

So I recently picked up a UPS ES750 from a buddy of mine. He had it working when I bought it and I did see it working with no issues. However, when I brought it home, it wouldn’t work. I press the power button and it flashes green for a few seconds, and then it stops flashing and the Red battery LED starts flashing and the unit beeps twice (rapidly) every 2 seconds. I’ve included a video of the issue

Hi Evan,

This issue would be with a battery that needs to be replaced or charged. Depending on how long they had it sitting or how long it took for you to plug it in the battery could have gone bad in that period. They may have also disconnected the battery when they gave it to you.

The replacement battery for this unit would be RBC17. This can be ordered from our website or if you need assistance in ordering it you could contact our sales line at 800-800-4272 option 3 option 1.

The manual for this unit can be found here http://www.apc.com/salestools/SCON-89HM8Q/SCON-89HM8Q_R4_EN.pdf
