Your auto parts store will have all kinds of self-restoring 12-volt circuit
breakers.

The easiest loss-of-power alarm is a wall wart connected to an alarm input on

Well
Try your local RV dealer. They have large size buss fuses that go between
the battery and the trailer power converter box.

Marine supply places. Since selling the boat, I buy stuff for my RV at West
Marine. Great stuff and the price is usually right.

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.

Sounds like a nice battery string to have for backup.
Good luck.

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
