Description
A reliable starting system is non-negotiable in racing and high-performance driving—weak cranking power costs you track time and reliability when it matters most. The YUASA YB10A-A2 Yumicron CX delivers 5-8% more cranking power than comparable high-output batteries while its lead/calcium construction resists vibration and thermal cycling, keeping you in the fight lap after lap. Low-maintenance design means you spend less time on battery diagnostics and more time driving.
