I got this UPS used, thought it just needed new batteries, but with new batteries in, it beeps beeps, fan looses power, beeps again and starts trying to startup again. This happens with the batteries connected or disconnected. With batteries connected, if power is pulled from the wall, after the 30 seconds the unit shuts down and does not attempt to start up.

Mark F K, truong808, does the cooling fan(s) blow or come on? If not, the system will sense tha ti is overheating and will shut down to prevent further damage. Also, a thermal sensor may be failing on the Mobo and thus keep the fan from initiating. The cheapest fix is to replace the fan. Worst case scenario is another Mobo may be the fix.
SOURCE: furnace starts properly, then shuts down, led flashes 8 times
The first thing to look at is the flame sense rod.
Shut off power to the furnace, remove, clean sensor with steel wool or sandpaper then reinstall the sensor. Reapply power and it should run properly.

HEY !! it's under warranty. I had one of these freak out on me in much the same way once in a while. I did the online help on APC's website. STAND YOUR GROUND if you don't get the answer you want. I held strong even after the "tech" said repeatedly that it was a building wiring fault, which it's not, and harassed him into exchanging it for a new one. Good luck
