SOURCE: APC Back UPS RS-1000 Overload LED with beeping sound after on.

in the end solution is you have to bring it nearest apc service.
if you loaded more than its max. capacity at past, the sensor of power is geting burn the sequare wave generator IC.
so you need help with that, olso complicated.
I live the same position with my rs1000, horrible :((

it seems that the inverter circuit of your UPS is dying. the solution here is you have to open up the UPS and check the inverter circuit. to make easier, check the power mosfet if its leaking.

You need to run recalibration on the unit.  The supplied PowerChute software & cable will allow you to do this if you hook the UPS up to a PC (I know it works with the serial cable, not sure about USB).  If you only have a MAC then I cannot offer a solution other than to buy the standalone PowerView device from APC.  It will cost a bit more than a battery, but may save you from buying needless batteries in the future.  I finally broke down an bought one, but note that I was still having the problem after the 1st recalibration.  By trial and error (and maybe a vague memory) I put my MAC in sleep mode, that dropped the load to stop the lights from flashing.  Then I recalibrated with a 22% load and now it finally seems better (lights no longer flashing).  This was with a Smart-UPS 1000.
Let me know if that helps.
