Battery Back ups (Mostly APC)
 

How would i know what size battery back up to buy? is there some type of online calculator i can check out. Is there various things on and in my machine i can add up to figure out how much, i wanna buy two to protect my computers and i don't wanna buy one thats too big, thats a waste of money and power, and i don't wanna buy one to small that'll just hurt my computers.

I bought an APC 300 watt last year and it saved my bacon a few times, but it was only good for 10-12 mintues running one desk top, monitor, router, and modem. But, plenty of time to properly shut down. Mostly valuable for short cut-outs of a second or so.

I found sizing calculation links that look usefull on page 5 of this article. hxxp://www.pcworld.idg.com.au/index.php/id;815595312
