Bn900m issue.

Bought the ups yesterday. Plugged the battery in and all devices and it worked. Lost power last night and it cut off. Now if I turn it on green light flashes for 10 seconds while powering devices and then turns off with a constant tone. Will do the same thing if I have nothing plugged in and I turn it on.
