- Maintenance-free sealed construction – no water additions required
- Spill-proof pressurized valve design for safe installation in any position
AGM Construction & Vibration Protection
The ACDelco 48PS battery uses absorbed glass mat technology where electrolyte is suspended in fiberglass mats between the lead plates. This construction creates a battery that’s far more resistant to vibration damage than conventional flooded batteries, making it ideal for trucks, SUVs, and performance vehicles that experience rough road conditions.
Our AGM design also provides faster recharge times and better performance in partial-state-of-charge conditions. The calcium alloy grid structure resists corrosion while maintaining conductivity, extending the overall service life of your battery.

Cold Cranking Performance & Electrical Capacity
With 760 cold cranking amps, the acdelco 48ps battery delivers strong starting power even when temperatures drop below freezing. This CCA rating exceeds the requirements of most Group 48 applications, providing extra margin for aging engines or winter conditions that increase cranking resistance.
The 70 amp-hour reserve capacity means your vehicle’s electrical systems can run for extended periods with the engine off. This capacity supports modern vehicles equipped with multiple computers, infotainment systems, and safety features that draw power even when parked.
Group 48 Fitment & Installation
The Group 48 case measures 10.87 inches long, 6.87 inches wide, and 7.5 inches high, making the ACDelco 48PS a direct replacement for factory batteries in many European and Asian vehicle models. Before purchasing, verify your current battery’s group size and terminal configuration to ensure proper fitment.
Terminal posts are positioned for top-mount connections with standard cable clamps. The battery can be installed in the engine bay, trunk, or under-seat locations thanks to its sealed, spill-proof design. Always secure the battery with the factory hold-down to prevent movement during operation.

Common Questions About the 48PS Silver Battery
Yes, the 48PS is designed as a direct replacement for any Group 48 battery application. The case dimensions (10.87″ L × 6.87″ W × 7.5″ H) match the industry standard Group 48 specification.
Verify your current battery’s group size label and terminal configuration before purchasing. The 48PS uses top-post terminals compatible with standard cable clamps. Some vehicles may use side-terminal or dual-terminal variants that require different battery models.
You should use a charger specifically designed for AGM batteries or one with an AGM charging mode. Standard flooded battery chargers may apply voltage levels (over 14.7V) that can damage the pressure valve system and shorten the acdelco 48ps battery’s service life.
AGM-compatible chargers regulate voltage to the 14.4V maximum safe for sealed batteries and often include desulfation modes that help maintain capacity. Many modern smart chargers automatically detect battery type and adjust charging parameters accordingly.
Under normal conditions, you can expect 4-7 years of service from the 48PS. Actual lifespan depends on climate, driving patterns, and electrical system health.
Vehicles driven regularly with trips longer than 20 minutes tend to maximize battery life because the alternator fully recharges the battery. Short trips, extreme temperatures, and high accessory loads accelerate aging. The AGM construction provides better cycle life than flooded batteries, especially in start-stop applications that cycle the battery more frequently.
No, the ACDelco 48PS is completely maintenance-free and sealed. You cannot and should not attempt to add water. The absorbed glass mat design and pressurized valve system recombine hydrogen and oxygen internally, eliminating water loss during normal operation.
This sealed construction is one of the key advantages of AGM technology over traditional flooded batteries. There are no removable caps, and the battery will never need electrolyte maintenance throughout its entire service life.
The 760 cold cranking amp rating indicates the battery can deliver 760 amps at 0°F for 30 seconds while maintaining at least 7.2 volts. This measurement reflects the battery’s ability to start your engine in cold conditions when oil is thick and engines require more cranking power.
Higher CCA ratings provide extra margin for aging engines, extreme cold, or vehicles with larger displacement engines. The acdelco 48ps battery’s 760 CCA exceeds most Group 48 application requirements, ensuring reliable cold-weather starting even as the battery ages.
Yes, the sealed, spill-proof design allows installation in any orientation except completely upside down. The valve-regulated system prevents electrolyte leakage regardless of mounting angle, making the 48PS suitable for trunk, under-seat, or compartment installations where space constraints require angled mounting.
Always use the factory hold-down bracket to secure the battery and prevent movement during vehicle operation. While the sealed construction prevents spills, the battery must still be held firmly in place to avoid vibration damage to internal components.
Yes, the AGM construction of the ACDelco 48PS makes it well-suited for start-stop systems. These systems cycle the battery hundreds more times per year than traditional vehicles, and AGM technology handles frequent shallow discharge and recharge cycles far better than flooded batteries.
The enhanced charge acceptance allows the 48PS to recover quickly during short driving intervals between stops. The absorbed glass mat design also resists the sulfation that typically shortens battery life in high-cycle applications.
