H-D AGM Original Equipment Battery
Keep your Harley-Davidson motorcycle ready for the road with the H-D AGM Original Equipment Battery. Designed for compatible Harley-Davidson motorcycles, this Absorbed Glass Mat (AGM) battery provides the electrical power required to start the engine and support the motorcycle’s electrical systems.
H-D AGM Battery
An AGM battery uses a specialized glass-fiber mat to hold the electrolyte inside the battery. This construction helps prevent free-flowing electrolyte and provides a sealed battery design suited to motorcycle use. Choosing the correct Original Equipment replacement helps ensure compatibility with your motorcycle’s electrical requirements and battery mounting location. H-D AGM Battery

Reliable Starting Power
The battery is an essential part of your motorcycle’s starting and electrical systems. It supplies the initial electrical power needed by the starter motor and supports other electrical components when required.
Battery condition can be affected by temperature, riding frequency, storage conditions and the electrical demands placed on the motorcycle. A battery that is correctly specified for your model helps provide the appropriate starting power and electrical performance when maintained according to the manufacturer’s recommendations.
Understanding AGM Battery Technology
Absorbed Glass Mat technology holds the battery electrolyte within a fiberglass separator between the internal plates. This design is commonly used in powersports batteries because it offers a sealed construction suitable for the demands of motorcycle operation.
Like other lead-acid batteries, an AGM battery needs appropriate charging and care to maintain its condition. Extended periods without riding, low temperatures and repeated short trips can affect battery charge. Using a compatible battery charger or maintainer and following Harley-Davidson’s battery-care guidance can help maintain battery performance during storage.
Choosing the Correct Replacement
Not every Harley-Davidson motorcycle uses the same battery. Battery specifications, dimensions, terminal positions and starting requirements can vary between models and model years. Selecting the correct Original Equipment battery is therefore important for proper fitment and electrical compatibility.
Before ordering, check your motorcycle’s model, year and original battery part number against the official Harley-Davidson parts catalogue. Do not assume that batteries with similar dimensions or appearances are interchangeable.
Installation and Maintenance
Always follow the motorcycle owner’s manual when removing or installing a battery. Use the correct terminal connections and installation procedure for your model, and ensure that the battery is securely mounted.
Inspect the battery and its connections periodically, and follow the manufacturer’s charging and storage recommendations. If your motorcycle has difficulty starting or the battery repeatedly loses charge, have the charging system and electrical connections checked before replacing the battery.
The H-D AGM Original Equipment Battery is intended for compatible Harley-Davidson applications. Verify the exact battery part number and fitment before purchasing to ensure that you select the correct replacement for your motorcycle.
