What ACDelco Owners Say

Drivers across the country trust ACDelco batteries for dependable starting power. Here’s what our community has to say about their experience.

Installed the ACDelco 48AGM in my Silverado last fall. We had weeks of below-zero temps this winter and it fired right up every single morning. The cold-cranking performance is outstanding.

Marcus T. Truck Owner — Minnesota

I manage a fleet of 40 delivery vehicles and we’ve standardized on ACDelco Professional batteries. Downtime from dead batteries dropped dramatically. These batteries hold up under constant start-stop cycles.

Sandra K. Fleet Manager — Texas

Put the ACDelco Voyager in my bass boat and it powers the trolling motor and fish finder all day. I get consistent output from sunrise to sunset. Exactly what I needed for tournament fishing.

Dale R. Marine Enthusiast — Florida

The ACDelco 94RAGM was the perfect fit for my BMW. European-spec fitment, high reserve capacity, and the maintenance-free design means I never have to think about it. Just reliable starts every time.

ACDelco Battery Questions Answered

Got questions about our batteries? We’ve answered the most common ones below to help you find the right ACDelco battery for your vehicle.

Our ACDelco Professional AGM batteries use absorbed glass mat technology that provides superior cycling capability, vibration resistance, and deep-discharge recovery — ideal for modern vehicles with heavy electrical loads and start-stop systems. ACDelco Advantage batteries deliver dependable starting power using proven flooded-cell technology at a more accessible price point, making them a great choice for standard vehicles with typical electrical demands.

Every ACDelco battery is designated by a BCI group number — like Group 48, Group 94R, or Group 78 — that corresponds to specific physical dimensions, terminal positions, and power output. Check your vehicle owner’s manual for the recommended group size, or use the ACDelco battery lookup information on our site. Common groups include 48 for many GM vehicles, 94R for European cars, and 51R for compact and mid-size Asian-make vehicles.

CCA stands for Cold Cranking Amps — the amount of current an ACDelco battery can deliver at 0°F for 30 seconds while maintaining at least 7.2 volts. Higher CCA ratings mean more reliable starts in cold weather. Our ACDelco Professional AGM batteries offer CCA ratings up to 770 amps, making them some of the most powerful automotive batteries available for harsh winter conditions.

ACDelco battery warranty coverage varies by product line. Our Professional Gold batteries come with up to 42 months of coverage, while the Advantage Series typically offers 18 to 30 months. Each ACDelco battery includes a date code stamped on the case that allows you to verify your warranty period. Visit our warranty information page for full details on coverage and the claims process for your specific battery model.

Absolutely. Upgrading from a standard flooded battery to an ACDelco AGM battery is a popular choice because AGM technology offers improved vibration resistance, longer cycle life, and better performance under heavy electrical loads. As long as the BCI group size matches your vehicle’s requirements, an ACDelco Professional AGM battery is a direct upgrade. However, if your vehicle originally came with an AGM, we strongly recommend replacing it with another AGM — not downgrading to flooded.

Yes — our ACDelco Voyager marine battery line is specifically engineered for boats, watercraft, and marine electronics. These deep-cycle batteries are designed to be discharged and recharged repeatedly, providing sustained power for trolling motors, fish finders, GPS systems, and onboard accessories. We offer multiple group sizes in our marine lineup to match different vessel requirements and power demands.
