Battery Recharge for Liebert PowerSure PSA
Yes, is the short aswer to your question. The battery should charge as you use the ups. If they don't then its likely the battery/s have failed. Lead acid batteries do not like being left discharged for any length of time. In a motor vehicle the battery gets a bit of shaking around, but in an ups they don't. If not used and left discharged, the plates quickly sulfate up reducing the efficiency to nearly zero. Test and replace any battery that cannot support a test load, such as a bright12v light or a 12v soldering iron connected to it. The length of time required to charge the battery/s depends on their capacity (in ampere/hours) and the charging rate. A 14.4 amp/hr battery charged at say 1 ampere will take 14-1/2hrs to charge.(just as a sample)

Liebert gxt2-10000rt208 fault indicator and A + E LEDs on. Did anyone know this alarm?
I'm going to go on a limb and say the unit also has the bypass indicator on as well, is that correct? A=On bypass due to overtemperature condition & E=On bypass due to inverter failure.
I can't see in the picture or hear it but is it beeping also? 1 second beep every 2 seconds? Thats on internal bypass. If none of this is true then you have a tricky problem.
