ACDelco 35PS Battery – Group 35 Professional Silver AGM
Our ACDelco 35PS battery is built for drivers who demand professional-grade reliability every time they turn the key. This Group 35 absorbed glass mat (AGM) battery delivers superior starting power and deep-cycle endurance for late-model vehicles with high electrical demands.
Designed to exceed original equipment specifications, the 35PS features calcium-alloy positive and negative grids that resist corrosion and maximize conductivity. Whether you’re powering advanced electronics, running accessories with the engine off, or facing extreme temperatures, this battery provides the reserve capacity and cranking amps professional technicians trust.
- Group 35 size – fits most Asian and select domestic vehicles (9.06″ L × 6.88″ W × 8.88″ H)
- Absorbed glass mat (AGM) construction for spill-proof operation and superior vibration resistance
- Calcium-alloy grid technology for enhanced corrosion resistance and longer service life
- High cold cranking amps (CCA) for reliable starts in freezing conditions
- Maintenance-free design – no water additions required throughout battery life
AGM Construction & Performance Engineering
The acdelco 35ps battery uses absorbed glass mat technology that suspends electrolyte within fiberglass mat separators between the lead plates. This design eliminates free liquid acid, making the battery completely spill-proof even if the case cracks.
AGM construction delivers three critical advantages over conventional flooded batteries: faster recharge rates after deep discharge, superior resistance to vibration damage, and dramatically lower self-discharge rates during storage. The tightly compressed mat assembly also enables higher power density in the same footprint.
Group 35 Fitment & Vehicle Compatibility
Group 35 designates standardized battery dimensions recognized by the Battery Council International (BCI). The acdelco 35ps battery measures 9.06 inches long, 6.88 inches wide, and 8.88 inches tall, with terminal posts positioned according to Group 35 specifications.
This size commonly fits Nissan, Subaru, Toyota, and select Honda models from the 2000s forward, particularly vehicles with advanced electronics and stop-start systems. Always verify your vehicle’s battery group size in the owner’s manual or by checking the label on your current battery before ordering.
Installation & Maintenance Requirements
Installing the ACDelco 35PS battery requires basic hand tools and attention to polarity. Always disconnect the negative cable first to prevent short circuits, then remove the positive cable and battery hold-down hardware.
Clean the battery tray and cable terminals with a wire brush before positioning the new battery. The acdelco 35ps battery is maintenance-free – the sealed construction eliminates traditional vent caps and water addition procedures.

Common Questions About the ACDelco 35PS Battery
The Group 35 size commonly fits Nissan Altima, Maxima, and Pathfinder; Subaru Outback, Legacy, and Forester; Toyota Avalon and select Camry models; and various Honda Accord years. Always verify your specific vehicle’s battery group size in the owner’s manual or by checking the existing battery label.
Vehicle manufacturers may specify different group sizes across model years and trim levels, so confirming compatibility before purchase prevents fitment issues.
AGM (absorbed glass mat) batteries suspend electrolyte in fiberglass mat separators rather than allowing free liquid acid inside the case. This design makes the acdelco 35ps battery completely spill-proof and dramatically more resistant to vibration damage.
AGM batteries also recharge faster after deep discharge, tolerate more discharge cycles without capacity loss, and self-discharge much slower during storage compared to conventional flooded batteries. These advantages make AGM technology ideal for modern vehicles with stop-start systems and high electrical demands.
Use only chargers with AGM-specific settings or smart chargers that automatically detect battery type. AGM batteries require slightly lower charging voltages (14.4-14.7V) than flooded batteries to prevent overcharging damage.
Most modern multi-stage smart chargers include AGM modes with appropriate voltage profiles. Older manual chargers designed for flooded batteries may overcharge AGM batteries, causing premature failure. Temperature-compensated chargers provide optimal charging across seasonal temperature variations.
Basic installation requires a 10mm or 3/8-inch wrench or socket to disconnect battery cables, and possibly a 10mm or 13mm socket to remove the hold-down bracket, depending on your vehicle. A wire brush cleans corroded terminals, and dielectric grease protects connections.
Work in a well-ventilated area and wear safety glasses. Always disconnect the negative cable first to prevent short circuits, and reconnect it last after installing the new battery. Consult your vehicle’s service manual for specific procedures, as some models require programming to prevent warning lights after battery replacement.
Typical AGM battery service life ranges from 4-7 years depending on climate, driving habits, and electrical system health. Vehicles in extreme heat climates (Southwest U.S.) generally see shorter battery life than those in moderate climates.
Frequent short trips without allowing the alternator time to fully recharge the battery reduce lifespan. Having your charging system tested annually helps catch alternator problems before they damage the battery. The acdelco 35ps battery’s sealed AGM construction eliminates maintenance requirements and resists the corrosion that shortens flooded battery life.
Yes, the AGM construction makes this battery suitable for vehicles with automatic engine start-stop technology. These systems subject batteries to many more charge-discharge cycles than conventional vehicles, requiring the deep-cycle capability that AGM chemistry provides.
If your vehicle originally came with an AGM battery from the factory, you must replace it with another AGM battery to ensure proper operation of start-stop systems and prevent warning lights. Check your owner’s manual or the label on your current battery to verify the required battery type.
Return your old battery to any automotive parts retailer, service center, or recycling facility that accepts lead-acid batteries. Most retailers offer a core charge refund when you return the old battery, typically $10-18.
Lead-acid batteries are among the most recycled consumer products, with over 99% of materials reclaimed to manufacture new batteries. Never dispose of car batteries in household trash – the lead and sulfuric acid pose serious environmental and health hazards. Many jurisdictions legally require battery recycling and impose fines for improper disposal.
