Well, it's the strangest....f#$**$ thing. My "Sams" batteries are sweating and leaking acid from the tops and they're not even hooked up? The loop is not completed and they are only tied to each other but not to the cart. I can hear them perkulating and see them leaking....very weird. I'm going to hookem all up and test voltage, but these crazy things make noise sitting all by themselves?
