For more information on your car's battery, refer to the Battery section in .

The original equipment Delco Freedom® battery is a completely sealed unit that never requires the addition of water or acid. The only openings in the battery are vent holes located on the sides of the battery case. The vents allow the small amount of gas produced in the battery to escape.

The automotive battery has three functions: first, it provides a source of energy to crank the engine; second, it acts as a voltage stabilizer for the electrical system; and third, it provides energy for a limited time when the electrical load used exceeds the output of the alternator.

When choosing a replacement battery, it is important to adhere to the original equipment specifications. If your car is a base version, the Cold-Cranking Amperage (cca) should be no less than 630 and the Reserve Capacity Rating should be no less than 90. If your car is a more luxurious version with lots of electric options (designated `ua1' by gm), the Cold-Cranking Amperage (cca) should be no less than 770 and the Reserve Capacity Rating should be no less than 115.
