battery location/1996 Deville

I believe it is located either under the back seat, or in the trunk.

LIFT YOUR BOTTOM UP FOR BACK SEAT. SHOULD HAVE A RED 4"LONG RED BOX UNDER THE HOOD THAT YOU CAN JUMP BATTERY FROM,JUST REMEMBER TO TAKE BLACK JUMPER CABLE AND CLAMP TO SOME PART ON THE ENGINE,RED CABLE TO POSTS UNDER RED BOX...GOOD LUCK
