Absorbed Glass Mat or AGM batteries are designed to eliminate water loss and are optimized to run strong without upkeep. Where long-term storage usually means the death of lesser batteries, this powerful AGM battery will run strong when needed, undeterred by infrequent use. This proves especially compelling for vehicles where acid leaks could arise such as ATVs, watercraft, and motorcycles. The YTX(H) or YTX High-Performance series features increased power and 30% more CCA performance over the regular YTX series for improved cold climate performance. These batteries come factory-activated, meaning the high-gravity acid is already filled, sealed, and charged in the factory before making it to your door.
