Yuasa Battery Co. is the worlds largest Original Equipment battery supplier in the motorcycle industry. Since many years they also supply Harley-Davidson with private label batteries. Zodiac offers the same top-quality batteries at very competitive prices. For most models we also offer a high output battery. High output batteries have more cold cranking Amps and are highly recommended for high compression motors. These Yuasa batteries come dry charged from the factory and must be filled with battery acid before use. As they are shipped dry there is no problem shipping these as air cargo. You can purchase battery acid from a local car shop or DIY store.
