Superior Starting Power: 320 Cold Cranking Amps

When it comes to the large-displacement engines found in modern Harleys, starting power is non-negotiable. The Drag Specialties GYZ20HL delivers a robust 320 CCA, offering a significant advantage over standard 270-300 CCA batteries. With its 20Ah (Amp-Hour) capacity, this battery provides the deep reserve power needed to support modern electronics, including fuel injection systems, high-output ignitions, security alarms, and LED lighting kits.

Advanced Lead-Calcium & AGM Technology

Built using Absorbed Glass Mat (AGM) technology, the GYZ20HL features high-density lead-calcium grids that are more efficient at holding a charge than traditional lead batteries. The electrolyte is completely trapped within the fiberglass separators, making the unit 100% spill-proof and leak-proof. This sealed, valve-regulated (VRLA) design ensures that no acid can escape to damage your bike’s finish, while also providing a longer shelf life and slower self-discharge rate during storage.

Extreme Vibration Resistance and Build Quality

V-Twin engines are notorious for heavy vibration, which can cause internal battery plates to shed active material and fail prematurely. The Drag Specialties GYZ20HL is constructed with reinforced internal components and a heavy-duty casing that absorbs mechanical shock. This rugged design ensures the battery maintains its structural integrity through thousands of miles of rough road conditions, providing the durability that long-distance riders and daily commuters depend on.

Factory Activated: Ready to Install

Convenience meets performance with the GYZ20HL. This battery is Factory Activated, meaning it arrives at your door filled, sealed, and fully charged. Unlike “dry” batteries that require hazardous acid handling and a lengthy initial charge, the GYZ20HL is ready for immediate “plug-and-play” installation. Its maintenance-free design eliminates the need to ever check fluid levels, allowing you to focus on the ride rather than battery upkeep.
