Description

This battery utilizes Absorbed Glass Mat (AGM) technology, providing up to twice the lifespan of traditional flooded batteries and offering exceptional performance in both high-temperature climates and cold weather conditions. Constructed with Stamped Grid technology, the DieHard Platinum AGM battery features a stronger positive and negative grid design that enhances durability and offers superior corrosion resistance, leading to increased lifespan. This advanced construction ensures full grid utilization for significantly more electrical flow compared to other grid designs. It is a maintenance-free, non-spillable unit, allowing for flexible installation in any vehicle location. The battery boasts impressive power specifications, including 900 cold-cranking amps (CCA) and 1000 cranking amps (CA), ensuring reliable starting power. Its reserve capacity is rated at 160 minutes, meaning it can power essential vehicle functions for an extended period if the alternator fails. The specified dimensions (Length: 13.9375 in, Width: 6.9375 in, Height: 7.5 in) and terminal configuration (DIN - Type A1, Negative Terminal Location: Top Left, Positive Terminal Location: Top Right) should be verified against the vehicle's original battery requirements. It is important to note that this DieHard Platinum AGM Battery (Part # H8-AGM) does not fit the 2021 Mercedes-Benz Sprinter 2500. For vehicles requiring an H8 size battery, it offers an exact fit for some Mercedes models like the E500 and ML350, though installation in the ML350 can be challenging due to its location. The battery is excluded from additional discounts and promotions, with the exception of Advance Rewards.
