Consistent Starting Performance: 310 CCA

Starting a large-displacement V-Twin engine requires a sudden, powerful burst of energy. The Duraboost DVX20HL-BS delivers a solid 310 Cold Cranking Amps (CCA), ensuring reliable ignition in various weather conditions. With an 18Ah capacity, it provides ample reserve power to support your bike’s essential electronics, from fuel injection systems to security alarms, making it a dependable choice for daily commuters and weekend cruisers alike.

Advanced AGM Technology

The “HL” in the model name signifies a high-output, long-life design. Using AGM (Absorbed Glass Mat) construction, the electrolyte is held in specialized glass mat separators rather than flowing freely as a liquid. This creates a leak-proof and spill-proof battery that can be mounted at various angles without risk of acid damage to your motorcycle’s chrome or frame. This sealed, valve-regulated (VRLA) design also offers a much slower self-discharge rate compared to conventional batteries.

Vibration Resistance for V-Twin Engines

Harley-Davidson motorcycles generate unique vibration patterns that can quickly destroy standard batteries. The Duraboost DVX20HL-BS is built with vibration-resistant technology, featuring reinforced internal components and a rugged outer case. This construction helps prevent plate shedding and internal mechanical failures, ensuring the battery maintains its structural integrity even when subjected to the high-torque pulses of a Softail or Dyna engine.

Factory Activated: Ready to Ride

One of the biggest advantages of the Duraboost V-Twin series is convenience. The DVX20HL-BS is Factory Activated, meaning it is filled, sealed, and charged at the factory under strict quality control. There is no need for the rider to handle hazardous acid or wait hours for an initial charge. It is maintenance-free and ready for immediate installation right out of the box, allowing you to spend more time riding and less time in the garage.
