The Power Source of the American Legend<\/h2>\n\n\n

Your Harley-Davidson\u00ae motorcycle deserves a powerful battery. You may ride a nimble Sportster, a road-dominating Dyna, or a cross-country Touring bike. For any of them, there is one truth: A proper battery is crucial for performance. You want every last amp of cranking power. A weak battery on a legendary machine is more than an inconvenience. It’s enough to ruin a weekend.<\/p>\n\n\n\n

Many of our visitors need help matching their OEM parts, with strings of numbers like 66000340A or 66010-97E, to the replacement batteries we sell. This comprehensive guide eliminates that ambiguity entirely. We provide a definitive cross-reference that maps your original Harley-Davidson\u00ae battery to one of the most trusted names in powersports, Yuasa, and to our premium AGM line, Big Crank (powered by Deka ETX technology). Use this guide to confidently select the right fit and superior power for your Harley-Davidson\u00ae motorcycle, every time.<\/p>\n\n\n\n

Why Cross-Reference Matters<\/h2>\n\n\n\n

Choosing an aftermarket battery is often a matter of logistics, cost, and superior technology. Sometimes, OEM parts have limited availability, or one needs an immediate replacement before a weekend ride. Or, as-is the case from the people we talk to, just want to shave $100 off the replacement costs.<\/p>\n\n\n\n

This is where the Big Crank line shines. Our private label batteries use proven Deka ETX Absorbed Glass Mat (AGM) technology. AGM is a superior battery construction that provides higher cranking amps, faster recharge rates, and exceptional vibration resistance. These are all necessary specifications for Harley-Davidson\u00ae motorcycles. And gets you back on the road with power to spare.<\/p>\n\n\n

Deciphering Harley-Davidson\u00ae OEM Part Numbers<\/h2>\n\n\n\n

Harley-Davidson\u00ae battery part numbers typically follow a pattern where the first numbers identify the core battery type and size. For example, 66000XXX usually points to a larger, Touring-style battery.<\/p>\n\n\n\n

A key point to note is the letter suffix. If your battery number ends in an ‘A,’ ‘C,’ or ‘E’ (like 66010-97C), this nearly always denotes a minor design revision or capacity upgrade. Critically, the core replacement model number is consistent, meaning a \u201c66000340\u201d is generally interchangeable with a \u201c66000340A\u201d and the replacement options will be the same.<\/p>\n\n\n\n

Battery Mart\u2019s Cross-Reference Table<\/h2>\n\n\n\n

This table is your one-stop resource for finding the perfect replacement. We cross-reference the OEM part, the widely known Yuasa equivalent for comparison, and our Big Crank (Deka ETX) model, along with typical Cold Cranking Amps (CCA). You can click on any of the numbers below and go straight to the battery or the closest equivalents we sell.<\/p>\n\n\n\n

Crucial Note:<\/strong><\/em> Always verify the physical dimensions and terminal orientation (positive\/negative location) before final purchase to ensure a perfect drop-in fit for your specific model year.<\/em><\/p>\n\n\n\n
