Unleash dependable, hard-hitting starting power in your classic V-twin cruiser or vintage touring machine with the Yuasa YHD-12 Yumicron CX 12-Volt Battery. Specially engineered to meet the brutal cranking demands of big-bore engines, the Yumicron CX series combines extra lead plates with advanced lead-calcium technology to deliver significantly higher Cold Cranking Amps (CCA) than standard conventional batteries. Whether you are prepping for a cross-country highway haul or firing up your engine on a crisp morning, this high-output power cell supplies the instant ignition punch required to turn over high-compression pistons with total confidence.Built to endure the punishment of the open road, the YHD-12 features a high-impact polypropylene container and heavy-duty internal separators that shield delicate internal components from extreme engine vibration and frame shock. Its specialized radial grid design maximizes electrical conductivity while minimizing internal resistance for rapid energy transfer. The advanced lead-calcium grid alloy dramatically reduces water loss and self-discharge during offseason garage layup, while translucent casing walls make routine visual fluid checks effortless.

• Special thin separators allow two extra plates per cell to be installed, for a 30 percent improvement in cranking performance
• Engineered to protect against corrosion, withstand vibration, and deliver high cranking power
