With my new PC (much better than before takes around 250 watts underload) my old ups (Intex Protector 725) is giving random quick beeps.
it has happened 2 times, all of a sudden when everything is fine it will start to make quick beeps that lasts forever, i just quickly turn off pc then my ups, then after a few hours it'll work fine again.

the beeps are different from when the ups switches to battery, at that time it makes distant beeps, example it'll beep then wait 5-7 seconds beep again, and follows this pattern.

What is wrong cant find the beep code info on intex website, i dont understand is the battery gonna die?
