Reliable Cranking for Large V-Twins: 385 CCA

Touring bikes equipped with Milwaukee-Eight or Twin Cam engines require a significant amount of energy to turn over. The Duraboost DVX30L-BS delivers a consistent 385 Cold Cranking Amps (CCA), providing the necessary “kick” to fire up high-displacement engines in a variety of climates. With a 30Ah (Amp-Hour) capacity, it also provides excellent reserve power to support your bike’s essential electronics, including fuel injection, security systems, and factory audio units.

Advanced AGM Construction and Safety

Unlike traditional “flooded” batteries, the DVX30L-BS utilizes AGM (Absorbed Glass Mat) technology. The acid is absorbed into specialized fiberglass mat separators, creating a 100% leak-proof and spill-proof design. This sealed construction is vital for protecting your motorcycle’s chrome, paint, and frame from corrosive acid damage. Additionally, the sealed Valve Regulated Lead Acid (VRLA) design significantly reduces self-discharge, allowing the battery to hold its charge longer during the off-season.

Engineered for Maximum Vibration Resistance

The high-torque pulses of a Harley-Davidson Touring engine can be brutal on internal battery components. Duraboost has engineered the DVX30L-BS with vibration-resistant technology, featuring reinforced internal grids and a rugged, impact-resistant case. This heavy-duty construction prevents the internal lead plates from shifting or shedding active material, ensuring a longer service life and preventing premature failure caused by the rigors of the road.

Factory Activated: Ready for Immediate Use

The Duraboost DVX30L-BS removes the hassle of traditional battery setup. It arrives Factory Activated, meaning it has been filled, sealed, and fully charged under strictly controlled manufacturing conditions. There is no need to handle hazardous acid or perform a lengthy initial bench charge. It is maintenance-free and ready for immediate “plug-and-play” installation, getting you out of the garage and back onto the open road faster.
