ACDelco 750 CCA AGM Battery
Our ACDelco 750 CCA AGM battery is engineered for drivers who demand uncompromising starting power in extreme conditions. Built with absorbed glass mat technology, this maintenance-free battery delivers 750 cold cranking amps to fire up full-size trucks, SUVs, and high-performance engines even in sub-zero temperatures.
We designed this premium battery with advanced valve-regulated design and spill-proof construction, making it ideal for modern vehicles with heavy electrical loads. The calcium-alloy grid technology provides superior corrosion resistance and extended cycle life, while the recombinant gas system virtually eliminates water loss throughout the battery’s service life.
- 750 cold cranking amps (CCA) for reliable starts in temperatures down to -40°F
- Absorbed glass mat (AGM) technology for vibration resistance and deep-cycle capability
- Maintenance-free design with sealed construction—no water additions required
- Calcium-alloy positive and negative grids resist corrosion and internal short circuits
- Group 48 (H6) fitment compatible with most full-size trucks, SUVs, and luxury sedans
AGM Construction & Performance Technology
The absorbed glass mat design in our acdelco battery 750 cca separates this power source from conventional flooded batteries. We use ultra-thin glass fiber separators that absorb and immobilize the electrolyte between the lead plates, eliminating free liquid acid inside the case.
This construction method delivers three critical advantages: exceptional vibration resistance for off-road and commercial use, dramatically reduced self-discharge rates during storage, and the ability to mount the battery in multiple orientations without leakage. The tightly compressed plate-and-separator assembly also enables faster chemical reactions during cranking, which translates to stronger starts when your engine needs maximum amperage.
Fitment & Vehicle Compatibility
This Group 48 (also called H6 or L3) battery measures 10.94 inches long, 6.89 inches wide, and 7.50 inches tall, with top-post terminals positioned for direct replacement in most domestic and import applications. We designed the acdelco battery 750 cca to fit full-size pickup trucks from Chevrolet, GMC, Ford, and Ram, as well as Tahoe, Suburban, Expedition, Silverado, and F-Series models from the past two decades.
The battery also serves as an upgrade for luxury sedans and crossovers originally equipped with lower-CCA Group 48 batteries, including many BMW, Mercedes-Benz, Audi, and Cadillac vehicles with start-stop systems. Before installation, verify your tray dimensions and cable-reach requirements, as some European models use slightly different terminal configurations.
Maintenance-Free Operation & Service Life
Our sealed valve-regulated design eliminates the periodic water-level checks required by conventional flooded batteries. The recombinant lid system converts hydrogen and oxygen gases back into water vapor during normal charging, maintaining proper electrolyte levels throughout the battery’s lifespan.
You’ll never need to remove vent caps or add distilled water, and the leak-proof case prevents acid spills even if the battery tips during installation or vehicle accidents. We built this battery to handle the high electrical demands of modern trucks and SUVs equipped with heated seats, navigation systems, premium audio, and trailer-towing packages.

Common Questions About Our 750 CCA Battery
This Group 48 battery fits most full-size pickup trucks and SUVs from Chevrolet, GMC, Ford, Ram, Toyota, and Nissan manufactured after 2000. Common applications include Silverado, Sierra, F-150, F-250, Ram 1500, Ram 2500, Tundra, Tahoe, Suburban, Expedition, and Yukon models.
The battery also replaces Group 48 (H6/L3) batteries in luxury sedans and crossovers from BMW, Mercedes-Benz, Audi, Cadillac, and Lincoln. Always verify your current battery’s group size and dimensions before ordering, as some trim levels use different battery sizes.
Under normal driving conditions with a properly functioning charging system, you can expect four to six years of service life from this AGM battery. Factors that extend battery life include regular vehicle use (at least once per week), parking in climate-controlled garages, and avoiding deep discharges below 50% state of charge.
Vehicles with start-stop systems, heavy accessory loads, or frequent short trips may see slightly shorter lifespan due to increased charge-discharge cycles. The three-year free replacement warranty covers manufacturing defects and premature capacity loss during the initial warranty period.
We recommend using a smart charger with an AGM-specific charging profile for best results. Standard chargers designed for flooded batteries may overcharge AGM cells, causing excess heat and shortened lifespan. Modern microprocessor-controlled chargers automatically detect battery chemistry and adjust voltage and current accordingly.
If you must use a conventional charger, select the lowest amperage setting (2-10 amps) and monitor battery temperature during charging. Disconnect immediately if the case feels warm to the touch. Never charge above 14.7 volts or allow the battery to gas or bulge.
Cold cranking amps measure the battery’s ability to deliver high current at 0°F for 30 seconds while maintaining at least 7.2 volts. A 750 CCA battery provides adequate starting power for most gasoline V8 engines and small-displacement diesel engines in moderate climates.
An 850 CCA battery offers approximately 13% more starting current, which benefits larger diesel engines (6.7L and up), engines with high compression ratios, or vehicles operated in extreme cold climates where temperatures regularly drop below -20°F. Unless your vehicle requires higher CCA for reliable starting, our 750 CCA model provides excellent performance and value.
Installation follows standard battery replacement procedures: disconnect the negative cable first, remove hold-down hardware, lift out the old battery, clean the tray and cable terminals, and install the new battery with positive cable connected first. No special tools or programming are required for most vehicles.
Some European vehicles with battery-management systems may require OBD-II coding to register the new battery and reset charging parameters. This ensures the alternator applies the correct charging voltage for AGM chemistry. Consult your owner’s manual or a qualified technician if your vehicle has start-stop or intelligent battery monitoring.
Yes, the sealed AGM construction allows mounting in multiple orientations without electrolyte leakage. The absorbed glass mat separator immobilizes the acid, so there’s no free liquid inside the case. However, we recommend upright installation (terminals on top) whenever possible for easiest access and optimal performance.
Avoid mounting the battery completely upside-down (terminals facing down), as this can stress the terminal seals and internal connections over time. Horizontal or angled mounting works well for tight engine bays or custom installations where space constraints require creative positioning.
This battery includes a three-year free replacement warranty from the date of purchase. If the battery fails due to manufacturing defects or premature capacity loss during the warranty period, we’ll replace it at no charge at any participating ACDelco Professional service center.
To qualify for warranty coverage, the battery must have been installed in a vehicle with a properly functioning charging system (13.8-14.7 volts). Keep your original purchase receipt and warranty card for claim processing. The warranty does not cover damage from physical abuse, improper charging, or installation in applications exceeding the battery’s specifications.
