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.
