Best lawn tractor battery

This is the answer. The best bang for the buck and as easy as any to use.
My tractor, my Porsche and my Tundra were each on one for 7+ months
over all of last winter (Ohio!) and started like they were just parked. These
have automatic circuitry and do not overcharge. Cheap and fully automatic.
