BX650LI-MS VERY short runtime

[BillP]

Hey guys, I am new to this forum so pardon me if I am not aware of some rules.

Back to the topic, I have BX650LI-MS backup UPS. It is around 6months old, for the first 4 months it was running normally. However this 2 last month, every time power goes out (happens at least once per 2 weeks), my ups would only provide power for about 1-3mins then it will start beeping fast and shutdown. Another thing to note is that before it beeps normally every few minutes, now it doesn't. It isn't overloaded since I have only one low-end desktop plugged into it. I also tried leaving it turned on/off before sleep to test if that affects its charging behavior. You guys got any ideas? Its a pretty important topic to me since I am losing my documents/projects due to small time window i have to save.
