If you're worried about gas venting, get a sealed AGM battery, something like an Optima redtop. They are sealed batteries, you can mount them anywhere and HOWEVER you want (upside down too!) and don't have to worry about that. The redtops also give more efficient power, better than your 50 dollar walmart battery anyways.
