Unleash hard-hitting starting muscle and ultimate electrical reliability in your high-displacement personal watercraft, heavy-duty touring bike, or big-bore utility vehicle with the Yuasa YB30CL-B Yumicron CX 12-Volt Battery. Purpose-built to handle the brutal cranking demands of massive engines, the Yumicron CX series combines extra lead plates with advanced lead-calcium technology to generate significantly higher Cold Cranking Amps (CCA) than standard conventional batteries. Whether you are hitting open waters for non-stop action or firing up a heavy engine on a cold morning, this high-output power cell delivers the immediate, punchy ignition needed to turn over high-compression pistons with total confidence.Engineered to endure the harsh punishment of marine and powersports environments, the YB30CL-B features a high-impact polypropylene container and heavy-duty internal separators that shield delicate components from extreme engine vibration and severe water turbulence. Its specialized radial grid design maximizes electrical conductivity while minimizing internal resistance for rapid energy transfer. Thanks to its advanced lead-calcium grid alloy, this heavy-duty 12V battery dramatically reduces water loss and self-discharge during offseason garage storage. Complete with translucent casing walls for effortless visual fluid checks, it offers the ultimate combination of high-reserve capacity, rugged casing durability, and proven Yuasa dependability.

• 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
