Hi, i'm having some problems my UPS (Kanji 1200va lcd) with it activates, under high loads, it starts to make a CLANK CLANK noise. It's supposed to withstand 720W, and my PC reaches 80%(576W) in the display at maximum load. (yes, it high end stuff). I already RMAed it once because after 4 months it started doing the same noise but even at 30%. It uses 2 12V 7Ah sealed lead-acid batteries in series. I tryed uping the load little by little, from 30%, and when it reaches 70% it starts. If it activates while onder high load, it does that noise but very loud, and then the pc shuts down. (which defeats the purpose of an ups) (i still haven't opened it yet, because of the waranty) i think it might be the batteries, which as they are from factory, they might be made-in-china™ and because of that, can't withstand the load. (but i don't know about this things so i may be wrong) the page is www.kanjitech.com.ar (it's more like a phantom page, very cheap, and missing links, even the email doesnt work xD) ...i should had bought a brand one, APC or a known one, but this was quite cheap and wanted to try) any idea of what might be the problem? EDIT: i forgot, i have the 24' LCD (switch), and the router and modem (transformer) plugged to the ups also
