I'll need to warn you that I had to have APC replace my first one and I'm not yet sure that the replacement won't have the same problem. If you google search, you can find others with the same issue. What would happen after an actual outage is the UPS would fail to recharge the battery. This wouldn't be noticeable right away but 3 or 4 days later when the battery charge bars would begin to drop out one by one. Eventually the device would alarm and display the missing battery icon. I'd need to unplug the UPS, remove the battery and plug it back in...sometimes 3 or 4 times. I'd hear a "click" and know it was OK. It would work until the next outage and...rinse/repeat. I believe it has something to do with a stuck relay. Anyway, since the replacement I've had no problems but, then again, I've had no outages. What you really need these things for is what you're seeing. It's those momentary dropouts that cause your PC to shutdown. A UPS, unless you buy some several thousand dollar type that uses tractor batteries, isn't meant to allow you to keep working all day. Rather it just lets you finish what you're doing and shut the thing down until the lights come on again. Sorry to be so long winded but when I saw that make/model (and APC is usually good), I cringed. It's the first APC to give me grief. Hope that helps.
I'm getting miffed here! Ever since those tornadoes passed through in Illinois I've been having a glitch. The winds were pretty high here in Chicago and seems like somewhere on the electric grid here some wires somewhere have been affected. Our power just goes off and on for split second, not long enough to have to reset the clocks or anything but long enough to shut my desktop computer down and my monitor. It doesn't mess with my laptop with the exception of for instance my internet connection drops for that split second also and Cnet says "oops I broke the internet" lol so I refresh the page and it's ok. So I'm thinking of buying this battery back up ->http://www.amazon.com/APC-BR1000G-Back-UPS-Uninterruptible-Supply/dp/B0038ZTZ3W/ref=sr_1_47?ie=UTF8&qid=1385314527&sr=8-47&keywords=battery+back+up+for+pc and use it in conjunction with this external battery ->http://www.amazon.com/gp/product/B0047E5B90 is this a good move?...Digger
