My backup unit keeps running the fans like it is running on Battery.
It does this about every 30 minutes or so.
It started doing this a few days ago.
I disconnected all equipment from it, except the following:
Unplugged the Backup unit, and the above devices took the backup unit down in 8 minutes.
This used to take about 20-30+ minutes to take it down.
I took the battery tray out and tested the batteries, and these are the readings I received.
1 - 13.41
2 - 13.44
3 - 13.65
4 - 12.30
Any thoughts on these readings, on rather they are good or not?
