Yuasa Battery YTZ12S Maintenance Free AGM 12-Volt Battery for Honda, BMW and Yamaha

Power up your high-performance sportbike, adventure touring machine, or heavy-displacement cruiser with the punchy, unyielding starter force of the YTZ12S Maintenance Free AGM 12-Volt Battery. Specially engineered to meet the intense electrical demands of modern multi-cylinder engines, this factory-activated powerhouse unleashes an impressive 210 Cold Cranking Amps (CCA) in a lightweight, space-saving footprint. Yuasa’s specialized radial grid architecture and extra internal lead plates maximize energy transfer, turning over high-compression engines instantly whether you are firing up for a frosty morning canyon run or rolling out after weeks off the road.

Built around advanced Absorbed Glass Mat (AGM) technology, the YTZ12S holds electrolyte completely absorbed within porous microfiber glass separators, making it 100% leak-proof and spill-proof. Delivered pre-filled, fully charged, and permanently sealed straight from the factory, this battery requires zero initial acid handling, zero water top-offs, and zero routine fluid maintenance. Its ultra-durable, vibration-resistant casing protects delicate internal lead plates against severe engine buzz and aggressive road impact, while the premium lead-calcium grid alloy retains a charge up to three times longer than conventional batteries during offseason storage.
