APC UPS1RM2U1500-1E PROBLEM

[Ego]

Hello, a few days ago I bought an ups apc from one of the largest stores in Poland as an outlet/after returning it, it is 100% functional according to the description. Today I connected it, an NC error popped up - the battery was disconnected, I connected it, the NC error with a triangle icon with an exclamation mark and the battery icon are still flashing. When I try to turn it on again, the UPS turns on but an error appears - fault code 11 and it beeps continuously. According to the instructions, it is an "inverter soft start failure". Is the battery dead or something else?

A brand new UPS must be plugged into the AC Mains for a minimum of 24 hours to recharge the battery so it’s 100%.

If the unit you purchased is a returned, refurbished, or NOS (New Old Stock. The battery may be depleted and need to be replaced.

If you don’t have any measurement tools such as a multimeter. You can simply use the UPS to inform you as to the battery voltage / capacity. Once the battery is 100% charged you can perform two basic tests from a manual (Self Test) and (Lights Out) test by removing AC Mains from the wall outlet.

You’ll probably see one of several scenarios from the battery recharged fine and the self test passes. The lights out test also passes while there is a 30% minimum load attached.

If so carry on with life . . . 👍

The next scenario is the self test passes but the lights out test provides only limited operational runtime when compared to the APC Runtime Calculator.

This is where you’ll need to consider replacing the battery or not. ☝️

The last scenario is the unit fails to pass the self test or even does pass the self test. But once you perform a lights out test the unit shuts down immediately or provides a very limited operational runtime that doesn’t even come close to the APC Runtime Calculator.

The option is obviously to replace the battery.

Given you just purchased this unit I would probably just return it for a replacement / refund! But, you can try the tests above to help you decide if it’s worth keeping.

Let us know what you decide and the final outcome. 👍
