Kevin, Given a power consumption of 10A, 460Ah batteries will give you about 46 hours of stand-by use...
The formula I used was: (available) 460Ah / 10A (consumption) = 46 hrs (time) Whether the "over 10 hours" affects the equation I'm not certain... If it does, maybe 460 hrs is more like it. Sorry.

Designed for back-up use. These are 2volt cells, 460amp/hr over 10hrs. What is written on them So we have 6 cells connected together to give 12volts. We are pulling , when everything is running, no more then 10amps. As a rough caculation, I am guessing the batteries should last for around 400+ hours. Anyone got a full caculation to find out how long they will last? Regards Kevin. Yahoo!
