The 2007 Chevrolet Tahoe is equipped with maintenance free battery. The battery is completely sealed except for two small vent holes in the side. These vent holes allow the small amount of gas that is produced in the battery to escape. The battery has three functions as a major source of energy: 1. Engine Cranking; 2. Voltage Stabilizer; and 3. Alternate source of energy with generator overload.
The battery positive terminal supplies Battery Positive voltage to the under hood fuse block and the rear fuse block. The under hood fuse block provides a cable connection for the generator and a cable connection for the starter. The battery negative terminal is connected to chassis ground G305 and supplies ground for the AD converter in the DIM. The following schematic illustrates the 2007 Chevrolet Tahoe Battery Parts and Components Assembly.
