To change the battery in a 2002 Cadillac DeVille, first, ensure the engine is off and the keys are removed. Open the hood and disconnect the negative cable (black) first, followed by the positive cable (red). Remove the battery hold-down bracket, then lift out the old battery. Place the new battery in the tray, secure it with the bracket, and reconnect the positive cable first, then the negative cable.
