Designed for trucks, SUVs, and performance cars with advanced electronics, our 94RPG provides reliable starting power and deep-cycle capability. The sealed, maintenance-free design eliminates water top-ups while delivering the durability professional technicians trust.
Whether you’re powering aftermarket accessories or replacing original equipment, the acdelco 94rpg battery meets the demanding specifications of today’s vehicles with recombinant technology that prevents acid leaks and extends service life.
- Group Size 94R – fits select GM, Ford, Dodge, and Toyota models with top-post terminals on the right side
- 800 cold cranking amps (CCA) for reliable starts in temperatures down to -18°C (0°F)
- 140 minutes reserve capacity provides extended power when the alternator isn’t charging
- Absorbed Glass Mat (AGM) construction resists vibration up to 15 times better than conventional batteries
- Calcium positive grid design maximizes conductivity and reduces self-discharge during storage
AGM Technology and Construction
The ACDelco 94RPG battery uses Absorbed Glass Mat technology that suspends electrolyte within glass fiber separators rather than free-flooding the cells. This construction allows the battery to handle deep discharge cycles while maintaining cranking performance, making it ideal for vehicles with start-stop systems or heavy accessory loads.
Our calcium-alloyed positive grids increase electrical conductivity while reducing the natural self-discharge that occurs during storage. The recombinant lid captures hydrogen and oxygen gases produced during charging, converting them back to water internally. This sealed design prevents acid spills even if the battery case cracks, protecting vehicle components and the environment.
Compatibility and Fitment
Group Size 94R Specifications
The 94RPG measures 12.4 inches long, 6.9 inches wide, and 7.5 inches tall, matching the BCI Group 94R footprint used in many full-size trucks and SUVs. The R designation indicates top-post terminals positioned on the right side when viewed from the front, which matters for proper cable routing in your engine bay.
This acdelco 94rpg battery fits 2003–2019 Dodge Ram 1500 models, 2009–2014 Ford F-150 trucks with larger engine options, and select Chevrolet Silverado and GMC Sierra configurations. Always verify your current battery’s group size and terminal orientation before ordering, as reversed terminals will prevent cable connection.
Cold Cranking Performance
We rate the ACDelco 94RPG at 800 cold cranking amps, measured at 0°F (-18°C) per SAE J537 standards. This specification indicates the battery can deliver 800 amps for 30 seconds while maintaining at least 7.2 volts, providing the surge current diesel engines and large displacement gasoline engines require during cold starts.
The 140-minute reserve capacity means the battery can supply 25 amps continuously for over two hours if your alternator fails, giving you time to reach service safely. This deep reserve supports extended accessory use with the engine off, such as running lights, radios, or power inverters at campsites or job sites.

Questions about the 94RPG Professional Gold Battery
The 94RPG fits vehicles requiring BCI Group Size 94R, which measures 12.4″ L × 6.9″ W × 7.5″ H with top-post terminals on the right side. This includes many 2003–2019 Dodge Ram trucks, 2009–2014 Ford F-150 models, and select GM full-size trucks and SUVs.
Verify your current battery’s group size label and terminal orientation before ordering, as the “R” designation is critical for proper cable connection. Check your owner’s manual or measure your existing battery tray if you’re unsure about compatibility.
The acdelco 94rpg battery uses Absorbed Glass Mat technology that suspends electrolyte in glass fiber mats between the plates, rather than flooding the cells with liquid acid. This design provides better vibration resistance, deeper discharge capability, and faster recharging compared to conventional flooded batteries.
AGM batteries like the 94RPG are completely sealed and maintenance-free—you never add water. They’re ideal for vehicles with start-stop systems, heavy accessory loads, or situations where the battery might tilt during off-road use. The trade-off is higher initial cost, but most users see longer service life that justifies the investment.
Our 36-month free replacement warranty covers manufacturing defects and premature capacity loss under normal automotive use. If the 94RPG fails within three years from purchase date, we’ll replace it at no charge at any authorized ACDelco warranty center nationwide.
The warranty requires proof of purchase and doesn’t cover damage from physical abuse, incorrect installation, or use in non-automotive applications. Register your battery within 90 days of purchase on our website to activate coverage and simplify any future warranty claims.
Battery replacement is straightforward for most DIY mechanics with basic hand tools. You’ll need a 10mm wrench or socket to remove terminal connections and loosen the hold-down bracket. Always disconnect the negative terminal first, then positive, to avoid electrical shorts.
The 94RPG weighs about 54 pounds, so have a helper or use proper lifting technique when removing the old battery and positioning the new one. Reconnect positive terminal first, then negative, and apply dielectric grease to prevent corrosion. If your vehicle requires computer memory preservation or other electrical precautions, consult a professional installer.
Expected service life depends on climate, driving patterns, and electrical loads, but most customers see 4–7 years from the 94RPG under normal conditions. Hot climates accelerate aging, while cold climates stress batteries during starting but generally extend overall lifespan.
Vehicles with frequent short trips that don’t fully recharge the battery, or those with heavy accessory use, may see shorter service life. The AGM construction of the acdelco 94rpg battery handles these demanding conditions better than flooded batteries, often lasting 30–50% longer in similar applications. Regular driving and occasional long trips help maximize battery longevity.
The 94RPG works with standard automotive battery chargers, but for best results use a charger with an AGM-specific setting. AGM batteries require slightly different charging voltage profiles than flooded batteries—typically 14.4–14.7 volts for bulk charging.
Avoid old-style manual chargers that can overcharge and damage AGM cells. Modern smart chargers automatically detect battery type and adjust voltage accordingly. If you use a battery maintainer during storage, verify it’s rated for AGM batteries to prevent overcharging that shortens service life.
Yes, the 94RPG’s 800 cold cranking amps provide sufficient power for most light-duty diesel engines, including Cummins 5.9L and 6.7L engines in Dodge Ram trucks. Diesel engines require more cranking current than gasoline engines due to higher compression ratios, and the 94RPG delivers the sustained current needed for diesel starts.
For heavy-duty diesel trucks or extreme cold climates below -20°F, verify that 800 CCA meets your engine manufacturer’s minimum specification. Some larger displacement diesels or those with dual-battery systems may require different battery configurations. The AGM design’s low internal resistance makes it particularly well-suited to the high-current demands of diesel starting systems.
