Constant beep problem with BACK-UPS RS 1100

[Ali10553]

So my UPS is approx 2 years old and once it's on it's running fine, but since 2 days some strange thing is happening. When I turn off my UPS for sometime and when I turn it back on, the green light blinks 4-5 times then it goes out and my UPS constantly starts beeping without ANY light on. I have to turn it off for it to stop beeping. Then I have to run through this procedure 6-8 times for my UPS to start working. Means I have to turn my UPS on and off again 5-7 times for it to FINALLY turn on fine. What should I do?

Sorry for the delayed reply.

When the UPS is first turned on, it runs a self-test to test the battery. The battery may be weak, so the test fails, and the UPS beeps to report the bad battery. 

Here is a link to an FAQ that discusses why the Back-UPS might beep
