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
= 460hrs. Calculation was way out.
Thanks to everyone who provided help. The real test will be a real test,
but if I can even get 80-100 hrs, I would be happy.

I owe its longevity to:

* Regular checks of electrolyte level

For various reasons, I declined the offer. But what an
