This is part from the EventLog.txt

I have only removed earlier lines. Nothing in between, or after.

There has been nothing out of the ordinary except this.

The self test in the log, I initiated manually, because it had been more than 7 days since the last one, but it had not automatically occurred as selected in the settings(Ups Start-up, and every 7 days since last test). I noticed this only because of the battery discharge "problem", and I do not know if they are somehow related.

So my question is obvious I suppose.. What is going on?

Assuming it still does it after pulling the battery and mains to reset it I would be inclined to think it is a faulty battery going open circuit.
