Hi Mex,
I guess I was up too early to comprehend what the OP said. Ty for pointing that out to me.
I prefer AGM. I prefer used Telcom jars as they don't cost an arm and a leg and the life of your first born son.
Proper charging is important, that statement applies to ALL battery types.
I will never place a "house" battery in the living quarters. It is a fine idea, until there is a failure. Then it quickly becomes a lousy idea. H2SO4 is not just an unpleasant smell.
There is nothing like not having to lay down in the snow to check electrolyte levels.
