Orange Lights on Back UPS BX600C-IN

[Anonymous user]

My UPS has some weird problems now. I believe that the battery is dead because it used to beep and show red lights. After some time, I checked the UPS and it had orange on the POWER and CHARGING lights and green on the BATTERY SAVER light. This continues even if I disconnect it from the power outlet.

I checked the user manual and there was nothing in it about orange lights. Does anyone know what it could mean?

MODEL: BX600C-IN

FAILURE HISTORY: Had too replace the battery once (during warranty period).
