@gjacobse Could just need new batteries maybe one of the cell's is low
While possible- it’s a new unit.
But might have been on a shelf for a while?

True,
Pulled it down and testing it… likely will need to exchange it. Reset, pulled the battery,.. still doesn’t want to turn on… but you clearly hear it ‘running’ while charging. -

Reset, pulled the battery,.. still doesn’t want to turn on… but you clearly hear it ‘running’ while charging.Does it have a network management card installed so that you can look at the logs? It could be a controller fault, a charging circuit fault, battery, and others.

@gjacobse Is the power input set to the correct voltage? We ran into something similar with the 9p line where the power from the street was 208 but of course the generator was at 240. With the UPS set to 208 and the batteries not at 100% it would not turn on while the UPS was running. We found it out the hardway when the power went on and the generator did not kick on and the batteries drained down. Then the generator repair tech got the generator on but it didnt matter since we couldnt turn on the unit since it was set to 208. Confirmed it with Eaton and all.

That's a good call - but sadly no.
I pulled it out of the rack - thankful for the use of a lift as pulling it down from twelve-fifteen feet up on a step-ladder would have been no joy.
Walked it across the warehouse and plugged it back in and noticed that the reported state of charge on the battery was 88%.
Wait, what now? you lost twelve percent, powered off and no load while I walked across the building? That can't be right.
Unit's going back RMA as failed..

Lead acid batteries (VRLA) can't be left uncharged for long periods of time. It cause sulphation on the cells and destroys the battery. Recommended storage time without charging is 6 months at room temperature.
So having an UPS sitting on a shelf is a bad idea. It should be hooked up at least every 6 month.
So this has nothing to do with Eaton. It's just how the battery chemistry works.
If you had the UPS sitting for a long time without installing it, this could be a factor.

Not true, it is a new unit. It is Eaton's responsibility. That or the distributor, depending on how it was purchased.
Either way, it is RMA as failed/bad on delivery.
Yes, the "problem" could be the battery, but still a vendor issue.

Technically, it could be a new unit that they purchased months ago and is finally being put into production.

Sure, the vendor have to replace it.
I'm just saying in case you buy an UPS of any brand and you have it as a spare sitting on the shelf in it's box for three years. Then there is a very high probablility the battery is damaged - even if you are covered under warranty. The higher the temperature, the lower the life span.
I brought this up just because it was mentioned that it's possible it has been sitting on the shelf for a while.

Found the issue with the assistance of Eaton Support.
The Remote Power On/Off connector - jumper- is missing.
Needs this jumper to power on

@gjacobse awesome.... random ports with secret functionality!

Going to be blunt here: That's just a plain fucking stupid, asinine, head up the ass design.
The only connectors on the back of the APC units we deploy are network, sensors, Network RJ45, Serial via RJ45, Female Extension Battery Pack connector, and some fans. Oh, and a ground screw. That's important too.

Don't forget to ground that sucker.
