What Are the Key Specifications of the AC Delco Silver BCI Group 47 Battery 47PS?

The AC Delco Silver BCI Group 47 Battery 47PS delivers 650 CCA, 800 marine cranking amps (MCA), and a 100-minute reserve capacity. It features a maintenance-free design with silver calcium alloy grids to reduce corrosion and extend lifespan. Measuring 10.25 x 6.88 x 7.75 inches, it fits GM models like Chevrolet, GMC, and Buick. Its reverse terminal configuration ensures secure placement in compatible vehicles.

This battery’s specifications are engineered to meet the demands of modern vehicles with advanced electrical systems. The 100-minute reserve capacity provides extended power for accessories during alternator failure, while the silver calcium alloy improves conductivity compared to traditional lead-antimony designs. For technicians, the stamped date code on the negative terminal simplifies warranty validation. The battery also features a state-of-charge indicator for quick visual health checks. Below is a comparison of key metrics against standard Group 47 batteries:

How Does Temperature Affect the AC Delco Silver Group 47 Battery’s Performance?

Extreme cold reduces CCA efficiency, but the 47PS’s silver calcium chemistry maintains reliable starts down to -40°F. In hot climates (100°F+), its corrosion-resistant grids prevent premature failure. Thermal runaway risks are minimized via vented lead-calcium construction. For optimal performance, park in shaded areas during summer and use a battery blanket in winter.

Temperature impacts battery chemistry at the molecular level. In freezing conditions, the electrolyte thickens, requiring higher energy output to initiate combustion. The 47PS compensates with optimized plate spacing that maintains ionic flow even at reduced temperatures. During heat waves, the vented design releases excess hydrogen gas before pressure buildup can warp internal components. Testing shows the battery retains 92% of its rated CCA after 500 thermal cycles between -30°F and 120°F. For hybrid vehicles with frequent engine restarts, this thermal resilience reduces wear on starter motors by ensuring consistent voltage delivery.

Which Vehicles Are Compatible with the AC Delco Silver Group 47 Battery?

This battery is optimized for GM vehicles, including Chevrolet Silverado (2014–2020), GMC Sierra (2015–2019), Buick LaCrosse (2010–2016), and Cadillac CTS (2008–2014). It also fits select non-GM models like the Chrysler 300 (2011–2014) and Dodge Charger (2011–2014). Always verify terminal placement and dimensions against your vehicle’s manual before installation.

“The AC Delco Silver 47PS stands out for its OEM-level integration in GM vehicles. The silver calcium technology isn’t just marketing—it measurably reduces grid corrosion, which is the primary cause of battery failure in modern cars. For drivers in temperature-extreme regions, this battery’s CCA stability is worth the premium.”

FAQs

How long does the AC Delco Silver 47PS typically last?

4–5 years with proper maintenance, outperforming average 3-year lifespans of conventional batteries.

Is this battery compatible with stop-start technology?

No—GM vehicles with stop-start require AGM batteries like the AC Delco Gold.

Can I install the 47PS battery myself?

Yes, but ensure terminals match your vehicle’s configuration and torque to 10–12 ft-lbs to avoid damage.
