one battery topped off and redy.

I was planning a 12V or 24V circuit around the house that gets topped
off with wind/solar. It's been in the back of my mind for a few years,
and why not now? That I have a conspicuous 110 gallon energy hog
sitting in my living room that needs a backup plan gives me all the more
reason to think about it.

I like to explore my engineer, geek, gentlemen scientist side and it
certainly beats the snot out of TV.

And, yes, I wouldn't use anything except for sealed cells. I have a
very bad habit of failing to maintain my batteries by topping them off
with distilled water.
