ACDelco 47PS Battery – Professional Silver Group 47
Our ACDelco 47PS battery brings professional-grade power to your daily driver. This Group 47 battery features absorbed glass mat (AGM) technology for superior vibration resistance and maintenance-free operation.
Designed for modern vehicles with demanding electrical systems, the 47PS delivers consistent cold-cranking amps even in extreme temperatures. We’ve engineered this battery with calcium-positive and silver-alloy negative plates to maximize cycle life and minimize self-discharge, so you’re ready to start every time you turn the key.
- Group 47 size fits popular import and domestic vehicles
- AGM technology provides spill-proof, maintenance-free operation
- Calcium-positive and silver-alloy negative plates resist corrosion
- Enhanced vibration resistance for rough road conditions
- Low self-discharge rate maintains charge during storage
AGM Construction & Battery Chemistry
The acdelco 47ps battery uses absorbed glass mat construction, where electrolyte is suspended in fiberglass mats between the plates rather than freely flooding the cell. This design eliminates spillage risk and allows the battery to operate in any position except fully inverted.
Our calcium-positive plates reduce gassing and water loss, while silver-alloy negative grids enhance conductivity and extend cycle life. The valve-regulated design vents hydrogen safely during charging while maintaining internal pressure for optimal chemical efficiency. This combination makes the 47PS ideal for vehicles with start-stop systems and high accessory loads.
Group 47 Sizing & Vehicle Compatibility
Group 47 is a common battery size measuring approximately 9.4 inches long, 6.9 inches wide, and 7.5 inches tall. The acdelco 47ps battery fits this footprint precisely, making it compatible with many Honda, Toyota, Nissan, and other import vehicles, as well as select domestic models.
Terminal Configuration
The 47PS uses top-post terminals in standard automotive configuration. Always verify your vehicle’s battery tray dimensions and terminal orientation before ordering. Our battery hold-down brackets and terminal clamps should match your factory setup for secure installation.
Cold-Cranking Performance & Temperature Range
Cold-cranking amps (CCA) measure a battery’s ability to start an engine at 0°F. The acdelco 47ps battery delivers robust CCA ratings engineered to meet or exceed OEM specifications for vehicles requiring Group 47 batteries.
AGM technology maintains higher voltage under load compared to conventional flooded batteries, providing faster engine turnover in cold weather. The absorbed electrolyte doesn’t stratify or freeze as readily as liquid acid, protecting internal components during winter storage.

Common Questions About the ACDelco 47PS Battery
The acdelco 47ps battery fits many Honda (Accord, Civic, CR-V), Toyota (Camry, Corolla), Nissan (Altima, Sentra), and other import vehicles requiring Group 47 size. Some domestic models also use this group size.
Always verify your current battery’s group number before ordering. The Group 47 footprint measures approximately 9.4″ L × 6.9″ W × 7.5″ H. Check your owner’s manual or the label on your existing battery to confirm compatibility.
The 47PS works best with a charger that has an AGM-specific charging profile, though most modern smart chargers include this mode. AGM batteries require lower charging voltages than flooded batteries to prevent overcharging and damage to the absorbed glass mat separators.
Avoid rapid charging above 10 amps. For maintenance charging during storage, use a quality trickle charger or battery maintainer rated for AGM batteries. Standard automotive alternators charge the 47PS normally during regular driving.
Under normal driving conditions, the acdelco 47ps battery typically provides 4-6 years of service, depending on climate, vehicle electrical demands, and maintenance practices. AGM construction generally outlasts conventional flooded batteries due to superior vibration resistance and reduced sulfation.
Extreme temperatures, frequent short trips, and extended storage without charging can shorten battery life. Maintaining clean terminals and keeping the battery fully charged when not in use maximizes service life. Our limited warranty covers defects—register your battery and retain your purchase receipt.
The acdelco 47ps battery can be mounted in any position except completely inverted (upside-down). The AGM design with absorbed electrolyte eliminates free liquid, preventing spills even when tilted.
However, we recommend installing the battery in the standard upright position as designed for your vehicle’s battery tray. The valve-regulated caps are engineered to vent gases properly when oriented correctly. Unusual mounting angles may affect warranty coverage if they lead to premature failure.
Our Professional Silver series, including the 47PS, uses AGM technology with silver-alloy negative plates for enhanced performance and longevity. This positions it between our Gold (conventional flooded) and higher-end Professional AGM lines.
The silver-alloy grids provide better conductivity than pure lead while reducing corrosion. Professional Silver batteries are ideal for late-model vehicles with moderate to high electrical demands. They offer maintenance-free operation without the premium pricing of our top-tier AGM models.
Yes, the acdelco 47ps battery’s AGM construction makes it suitable for vehicles with start-stop technology, though we recommend confirming your vehicle’s specific requirements. AGM batteries handle the frequent cycling demands of start-stop systems better than conventional flooded batteries.
The absorbed electrolyte design maintains capacity through repeated partial discharge cycles. For vehicles with enhanced start-stop systems or heavy regenerative braking, consider our enhanced flooded or premium AGM batteries specifically rated for advanced start-stop applications.
Automotive batteries contain lead and sulfuric acid, requiring proper recycling. Most auto parts retailers and service centers accept used batteries for recycling, often offering a core charge credit.
Never dispose of batteries in regular trash or pour acid down drains. Many states require battery retailers to accept old batteries when you purchase a replacement. Transport your old battery upright in a plastic container to prevent leaks, and take it to a certified recycling facility or retailer participating in battery recycling programs.
