I read somewhere a few years ago that the battery was located under the rear bench for better weight distribution in lieu of being placed in the engine compartment. This is why it is open vented to outside atmosphere. On those Optima batteries, are those open vents on top, or relief valves? Personally, I wouldn't attempt modification of a battery that is not designed to be located on interior of the vehicle. just my dime.
