RE: Battery on Ground
I've been told that storeing a bat on the floor will discharge it is actually a myth. What actually discharges it is the dirt and moisture that will collect on top of the bat, createing a path for millavolts to travel between posts. Ive tested this in the shop during our pm schedule, and have seen as much as .6 volt going across the top of the battery. Keeping it on a board I think will help insulate it from the cold, but I would buy one of those battery tenders that will keep your bat at charge. Not a charger, those will continue to charge and will overcharge your battery and ruin it. Batteries to a live long life need to be cycled, which helps previent calcification on the plates. The battery tender will do just that, and they are cheap at any battery outlet, automotive store, or at your locat Wally world.
