ACDelco Gold AMG Vehicle Batteries are a high quality alternative to Original Equipment (OE) parts. These batteries are remarkably charge-receptive, have high cycling capabilities. Absorbed Glass Mat (AGM) 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. Engineered with heavy, thick plates, ACDelco Gold AGM Voyager batteries can withstand the potential damage of continual deep discharging and recharging. Both positive and negative grids are built with Lead-Calcium alloy to help maximize corrosion resistance, optimize cycle life, and reduce water consumption for battery durability. Quick-glance charge monitoring for worry free use is also included. ACDelco Gold parts are manufactured to meet your expectations for fit, form, and function, making them a smart choice for General Motors vehicles, as well as most makes and models, including special applications. These high-quality parts are backed by General Motors. Some ACDelco Gold parts may have formerly appeared as ACDelco Professional.
