1. AGM (Absorbent Glass Mat) batteries
2. Lead-acid batteries
3. Lithium-ion batteries

AGM (Absorbent Glass Mat) batteries:
AGM batteries are known for their durability and maintenance-free characteristics. They contain a glass mat that absorbs the electrolyte, making them spill-proof and resistant to vibration. These batteries typically have a longer lifespan than traditional lead-acid batteries and provide reliable starting power. For example, the Harley-Davidson part number 65989-00A represents a popular AGM battery option designed for Sportster models.

Lead-acid batteries:
Lead-acid batteries are traditional battery types that have been used in motorcycles for decades. They consist of lead plates and a liquid electrolyte. While they are generally less expensive, they require regular maintenance and are more susceptible to damage from vibrations. Riders who prefer vintage or classic models often choose lead-acid batteries for authenticity. A typical example of this battery is the Harley-Davidson part number 65989-97, commonly used in older Sportster models.

Lithium-ion batteries:
Lithium-ion batteries are gaining popularity due to their lightweight design and high energy density. They provide quicker starts and longer service life compared to conventional batteries. Lithium-ion batteries are also less affected by temperature extremes. However, they are more expensive than other options, which can be a consideration for budget-conscious riders. A representative model for Sportster is the Shorai LFX14A1-BS12, known for its performance and lightweight characteristics.

Choosing the right battery for a Harley-Davidson Sportster involves considering factors such as budget, maintenance preferences, and performance expectations. Each battery type presents specific benefits and drawbacks, allowing riders to select the best option for their needs.
