Choosing the Right Harley-Davidson® Motorcycle Battery

Your Harley isn't just any motorcycle, and its battery isn't just any battery. The unique demands of a powerful V-twin engine and the vibrations of the open road require a battery built for the job. Below, we'll help you understand the key factors in choosing a battery that will keep your bike starting strong for years to come.

Understanding Battery Types: AGM vs. Lithium

  • AGM (Absorbed Glass Mat): This is the most popular type of Harley-Davidson® replacement battery. AGM batteries are sealed, maintenance-free, and highly resistant to vibration. They deliver reliable power and are a perfect choice if you want a dependable, long-lasting battery that doesn't require maintenance. Our Big Crank and Yuasa batteries are great examples of high-quality AGM options.
  • Lithium (LiFePO4): A newer, high-performance option for Harley® riders. Lithium batteries are incredibly lightweight, offer an extremely long shelf life, and provide a huge boost in cranking power. While they are a higher-cost upgrade, their performance and durability make them an excellent choice for riders seeking maximum power and reduced weight.

Why Cold Cranking Amps (CCA) Matter for V-Twin Engines

Cold Cranking Amps, or CCA, is a measure of a battery's ability to start an engine in cold temperatures. For a Harley-Davidson's powerful V-twin engine, a high CCA is critical. A battery with a low CCA rating can struggle to turn over the engine, especially in colder weather. We recommend choosing a battery with a CCA rating that meets or exceeds your bike's original equipment manufacturer (OEM) specifications to ensure a reliable start every time.

Frequently Asked Questions (FAQ)

Q: How much does a Harley-Davidson® battery cost?

A: The price of a Harley® battery can vary widely depending on the battery type, the specific model of your motorcycle, and the brand. Our prices range from around $100 for standard AGM batteries to over $300 for high-performance lithium models.

Q: What type of battery does a Harley-Davidson® use?

A: Most Harley-Davidson® motorcycles come standard with an AGM battery, which we highly recommend as a replacement. However, many riders choose to upgrade to a lithium battery for improved performance and a lighter weight.

Q: How do I know which battery is right for my specific Harley-Davidson® model?

A: The easiest way to find the right battery is to use our battery finder tool at the top of the page. Simply enter your bike's year and model to see a list of batteries that are a guaranteed fit. You can also contact our team of experts for personalized recommendations.

Q: Is it difficult to replace a Harley® battery myself?

A: For most models, replacing a Harley® battery is a straightforward process that can be done at home with a few basic tools. We recommend following the instructions in your motorcycle's owner's manual. Remember to always disconnect the negative terminal first and connect it last.
