Battery Replacement for a GM Vehicle

POWERFUL BATTERIES. EXPERT INSTALLATION. ALL BACKED BY GM.

Did you know your Certified Service experts are trained to inspect your vehicle’s battery and determine if failure is imminent? Your vehicle’s battery supplies and stores electrical energy from the alternator when the vehicle’s engine is running. Vehicle batteries provide energy to start the engine, plus they supply power to accessories when the engine is not running. Both the cold of winter and the summer heat can wear on auto batteries. No matter the season, we’ve got you covered with limited warranties that hold their charge.

Before you head out on your next trip, be absolutely sure your battery is at its best with an auto battery inspection. Should you need to replace the battery, we proudly offer a wide range of ACDelco Auto Batteries for the best combination of longevity, power, and price. Don’t wait until your battery dies — have your dealer check your battery’s health.

Choosing The Right Replacement Battery

Choosing the right battery for your auto battery replacement can be tricky. The right auto battery requires the right size, reserve capacity, and cold-cranking amps. You also need to consider the brand and how long the auto battery has been sitting on the supplier’s shelf.

If you have any doubts, rely on an expert or consult your Owner’s Manual to choose the right battery for your vehicle battery replacement needs.

What is more important, Cold-Cranking Amps or Reserve Capacity?

A: The Cold-Cranking Amps (CCA) test is the number of amps required to crank an engine for 30 seconds at 0 degrees Fahrenheit. Due to lower-viscosity engine oils, gear reduction starters, and smaller engines, having the right amount of CCA is required but not too much. More CCA will not start your car faster. The Reserve Capacity test is the number of minutes that a battery will last with the headlights left on or at a 25-amp draw. Due to the increased electronics in a vehicle, having as much Reserve Capacity as possible is now more important than having the excessive CCA.

How can I tell how many Cold-Cranking Amps my battery has?

A: Most battery manufacturers put the CCA rating right on the label of the battery. Be careful when shopping for batteries as some manufacturers put on the label a reference to “CA”. This is a reference to “Cranking Amps”, this test is done at 32 degrees Fahrenheit and not at 0 degrees Fahrenheit like the Cold-Cranking AmpS (CCA) test.

How can I tell how much reserve capacity my battery has?

A: This should be on the label right under the CCA rating of the battery.

Does this battery perform well in cold weather?

A: It is important to have the right battery for your vehicle. Refer to OEM specifications in your Owner's Manual or an OEM driven supplier such as ACDelco.

How long does this battery last without losing its charge?

A: All batteries need to be maintained. Parasitic drains in a vehicle can deplete a battery in 2-4 weeks. To be safe, vehicles should be started once a week or once every other week and idled for 5 minutes to ensure that the battery retains a reasonable state of charge.

If my car has a ‘start-stop’ feature, does this affect which type of battery my car has?

A: In the case of GM vehicles, AGM batteries are required for Start-Stop vehicles. Use of a flooded battery will result in the life only being about 4-6 months. Most other vehicle manufacturers are using AGM for these vehicles as well.
