Description

Power up your heavy-displacement touring bike, high-output cruiser, ATV, or personal watercraft with the unrelenting starting strength of the YTX20L Maintenance Free AGM 12-Volt Battery. Specially engineered to meet the massive electrical loads of big-bore engines, this heavy-duty battery packs a formidable 270 Cold Cranking Amps (CCA). Yuasa’s specialized lead-calcium grid structure optimizes electrical conductivity to deliver immediate, punchy ignition every time you press the starter button, so you can roll onto the open highway or hit the water with total confidence.
Built around advanced Absorbed Glass Mat (AGM) technology, the YTX20L traps electrolyte completely inside porous microfiber glass separators, creating a fully sealed, leak-proof, and spill-proof unit once activated. Once sealed, this maintenance-free design permanently eliminates the hassle of checking fluid levels or adding water, while offering superior resistance against intense chassis vibration and rough terrain shock. Its premium lead-calcium grid alloys hold a charge up to three times longer than standard conventional batteries during offseason storage, ensuring your ride stays primed and ready to perform.
