Product details
Power up your big-bore cruiser, heavy touring motorcycle, ATV, or utility vehicle with the dependable starting force of the Yuasa YTX20 Maintenance Free AGM 12-Volt Battery. Specially engineered to meet the aggressive cranking requirements of high-displacement engines, this heavy-duty battery packs a formidable 270 Cold Cranking Amps (CCA). Yuasa’s high-density radial grid design maximizes electrical conductivity to ensure fast, crisp ignition every time you press the starter button, letting you hit the highway or charge down remote backtrails with total confidence. Built around advanced Absorbed Glass Mat (AGM) technology, the YTX20 holds electrolyte completely absorbed inside porous microfiber glass separators, creating a leak-proof and spill-proof power cell once activated. Once permanently sealed, this maintenance-free setup eliminates the routine chore of checking fluid levels and adding distilled water. Its rugged construction provides exceptional protection against severe engine vibration and trail pounding, while premium lead-calcium grid alloys hold a charge up to three times longer than standard conventional batteries during offseason layup.
