I received a replacement unit couple of days ago. I have been using it since then hoping it calibrates itself properly.
But one of the problems with the original unit is replicated in this new one.
UPS backup time drops significantly within minutes of a power cut.
Here is a video demonstration.
As you can see it takes it just a couple of seconds to drop from 100% to 50-60%.
I would imagine that something is wrong with the batteries or the installation process. I am trying to get this investigated. APC Gurgaon guys have not been very responsive to this complaint. The typical response I got was that the backup I am getting should be enough for the power cuts we get here in Gurgaon.
My problem is… This is not what I paid for. I had asked them to provide a solution that gives me 6-7 hours of backup. The system shows that the UPS is capable of around 4 hours of backup. In reality, it seems to give just around 2-2.5 hours of backup.
