Starting the Revolution AGM Battery Infographic

ACDelco Absorbed Glass Mat (AGM) Battery

The ACDelco AGM range represents the very best in advanced battery technology for the most highly developed luxury cars and most advanced fuel-saving technology, including Stop/Start and regenerative braking.

AGM Plate separators reduce internal resistance, providing significant improvement in all performance criteria, including increased cycling ability, faster recharge acceptance and improved cranking power in Partial-State-Of-Charge (PSOC).

The AGM Range is ideal for highly-advanced stop-start vehicles, high-end luxury vehicles that have higher electrical accessory loads or performance vehicles that require a higher CCA starting battery with improved cyclic ability.

At GM Genuine Parts and ACDelco, we strive to blend quality and expertise to keep you moving forward

ACDelco Professional Automotive AGM Batteries have high cycling capabilities, are remarkably charge-receptive, and are necessary for ‘start/stop’ vehicle applications. The Absorbed Glass Mat design is 100% leak and spill proof because the Electrolyte is permanently held in the glass mat separator instead of free flowing within each cell. Oxygen recombination reduces water loss and reassures maintenance-free performance. ACDelco Professional Automotive AGM Batteries have longer life expectancy in traditional vehicle applications, due to a maintained pressure on the plates which significantly reduces the amount of active mass lost from the grid. ACDelco Professional Automotive AGM Batteries also have a 36 month Free Replacement Period.
