What you really need to do is a load analysis to see how much average current you are using over a larger period of time. 10 amps might be the peak, but most equipment spends the majority of the time at idle current. very simplified- you could take 4.6 amps/hour for about 100 hours. real

Kevin, Before I take a stab at this could you give me a rough estimate of the physical size of the battery? Where I'm headed with this is I'm trying to ascertain if your cells are truly rated at 460 amperes for a 10 hour duration or whether it's actually 460 ampere-hours (amps multiplied

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.

Kevin, I suspect that you have lead-acid wet cells, which emit corrosive vapors and hydrogen gas when charging. Be very careful to enclose these cells in containers that are vented to the outside air. Normally, one would use sealed, nonspillable cells for such duty. Your rough calculations are
