I wanted to replace my ageing APC RC1100 with APC 600VA. The old one’s just got no more juice in it and its hard to find a replacement battery for it. I was wondering would a 600VA suffice for my computer?
Your old UPS uses two 9ah batteries in series I think. The 600VA UPS uses only one battery. I suggest getting the batteries of the old UPS replaced from some battery dealer. They take old batteries and give 50-100 discount per battery when you buy new one from them.
