47-55.1 Battery Placement Question

[mr48chev]

Old thread but a good one.

This time around I plan to use an under the backseat battery for 2000 or so Cadillac Deville DTS like the one in the 2000 I used to have. They are a Group 79 that is Height (in): 7-3/8 Inch Length (in): 12-1/16 Inch Width (in): 7-1/16 Inch and put it behind the cross brace behind the seat in a cabinet/ box back there that will hold the battery, speakers and a tucked away storage box. They are designed to vent out through the floor with a vent setup that I will probably snag at a wrecking yard. if I can't just hook a hose to the vent on the battery.

I should note that mid 70's Audi 5000 had the battery under the back seat and vented through the floor.. I had one of those back 20 years ago.
