i have to take the battery out if a 04 porsche 911 carrera, is there anything i should know before i go over there and take it out? Im thinking of just taking some cresent wrenches and a flat head screw driver. Ive never even seen the engine compartment so i dont know if the battery is gunna be tucked way in the back and its gunna be a pain in the ass to get out. too bad its not a toyota 911
