Buying Guide: High Torque Cranking Power Battery for Harley Davidson Fatboy FLSTF
Understanding High Torque Cranking Power
When I first considered upgrading the battery for my Harley Davidson Fatboy FLSTF, I quickly learned that high torque cranking power is essential. This feature ensures that my bike starts reliably, especially during cold weather or after long periods of inactivity. High torque cranking power translates to quicker starts and a more reliable performance, which is something I absolutely needed.
Battery Types and Chemistry
I found that there are several types of batteries available, each with different chemistries. The most common ones are lead-acid, AGM (Absorbent Glass Mat), and lithium-ion. I learned that AGM batteries offer better vibration resistance, which is crucial for my Harley. Lithium-ion batteries are lighter and can provide more cranking power, but I had to consider their higher cost.
Cold Cranking Amps (CCA)
Cold Cranking Amps (CCA) is a vital specification that I focused on. CCA measures a battery’s ability to start an engine in cold temperatures. For my Fatboy, I aimed for a battery with a CCA rating that exceeded the OEM specifications. This extra power gave me peace of mind that my bike would start reliably, even in the chill of winter.

I found that some aftermarket batteries can be slightly different in size, so checking dimensions was critical. A snug fit minimizes movement and potential damage while riding.
Weight Considerations
Weight was another factor that influenced my decision. While I appreciated the lightweight advantages of lithium-ion batteries, I also considered how the weight distribution could affect my bike’s handling. I ultimately aimed for a battery that balanced weight with performance to maintain the riding experience I love.
Maintenance and Lifespan
I learned that maintenance requirements vary significantly between battery types. AGM batteries typically require less maintenance than traditional lead-acid batteries. I wanted to choose a battery that would offer longevity and reliability without frequent upkeep. This consideration led me to prefer a low-maintenance option.
Warranty and Support
A good warranty can provide peace of mind. I carefully reviewed the warranty terms offered by different manufacturers. A longer warranty often indicates the manufacturer’s confidence in their product. I also looked for companies with solid customer support in case I needed assistance or had questions after my purchase.
Price vs. Value
While I had a budget in mind, I realized that investing in a high-quality battery was crucial for my Harley’s performance. I compared prices across different brands and models, keeping in mind the features that were most important to me. I aimed for a balance of affordability and reliability, knowing that a good battery is an investment in my riding experience.
