Back-UPS ES 700 problem - constant beep, no led

    Hi all. I have a problem with my ups. 
    My battery was finished an year ago. Battery unplugged from UPS. 

    A few days ago I changed the battery with an original one. I mount it, connect ups to the power socket , no consumers plugged to ups, and when i press power button i heard a constant tone, no led lighted visible.  This sound is ending when i press power button again. 

    Just after power on, before the constant tone, i heard o noise like a relay trying to connect for 1-2 seconds.

    Thank you, waiting for a solution.
