SEALED AGM WITH THICKER, HEAVIER PLATES. WEIGHS 20% MORE THEN COMPETITORS. ITS SIMPLE - MORE LEAD, MORE BATTERY LIFE AND STARTING POWER. WHY PUT ANYTHING ELSE IN YOUR BIKE? A Heavy Duty Separator increases life, is resistant to shock and vibration to prevent shorts. HEAVY duty plates and grids are inside the battery for durability. Our sealed motorcycle batteries feature Absorbed Glass Mat technology (AGM for short). This design dramatically improves a battery's performance in the following areas: A) True sealed and maintenance-free design, you'll never have to check or add electrolyte again, unlike conventional batteries which require periodic fluid checks. B) Liquid-free AGM design, will not leak or corrode on expensive paint and chrome, and also eliminates corrosion around the battery terminals. C) AGM batteries have less internal resistance which allows them to produce more discharge current (cold cranking amperage) vs. comparable conventional ""wet"" batteries, and AGM batteries also recharge faster. D) Better resistance to both heat and vibration, a major cause of failure in conventional motorcycle batteries. E) Much slower self-discharge rate, (3% vs.15% per month) means longer periods between battery recharging over periods of non-use, like winter months or vacations. Banshee Battery General features Sealed Construction Banshee's unique construction and sealing technique ensures that no electrolyte leakage can occur from the terminals or case of any Banshee battery. This feature insures safe, efficient operation of Banshee's batteries in any position. Banshee batteries are classified as "Non-Spillable" and will meet all requirements of the International Air Transport Association. Absorptive Glass Mat System (AGM System) Banshee batteries make use of fine mat separators (glass fiber) wherein sufficient electrolyte is absorbed to provide the longest life and steady service. This system prevents escape of electrolyte from the separator which causes leakage. Gas Recombination Banshee batteries incorporated unique design that effectively controls generation of gas and allows recombination of over 90% of gas generated during the normal use. Maintenance-Free Operation During the expected floating service life of Banshee batteries, there is no need to check the specific gravity of the electrolyte or add water, whi
