My Buying Guide on High Torque Cranking Power Battery For Harley Davidson Fatboy FLSTF
When I decided to upgrade the battery on my Harley Davidson Fatboy FLSTF, I quickly learned that choosing the right battery is crucial for performance and reliability. With so many options on the market, I’ve compiled my insights into a buying guide that will help you make an informed decision.
Understanding High Torque Cranking Power
First off, let’s talk about what high torque cranking power means. This feature is essential for big V-twin engines like my Fatboy. It ensures that the battery delivers the necessary power to start the engine smoothly, especially in colder weather or after prolonged periods of inactivity. I found that a battery with high cranking amps (CA) and cold cranking amps (CCA) is vital for consistent performance.
Key Features to Consider
- Cold Cranking Amps (CCA)
I learned that the CCA rating indicates how well the battery performs in cold temperatures. For my Harley, I looked for a battery with at least 200 CCA to ensure reliable starts in various conditions.
- Reserve Capacity (RC)
Reserve capacity is another feature I paid attention to. It measures how long the battery can run on its own without the engine running. A higher RC gives me peace of mind, knowing that my bike’s electrical systems will function longer if I ever face a charging issue.
- Battery Type
There are several types of batteries to choose from, such as Lead-Acid, AGM (Absorbent Glass Mat), and Lithium. I opted for an AGM battery for my Fatboy because it offers a good balance between power, maintenance-free operation, and durability.
- Dimensions and Fit
I made sure to check the dimensions of the battery to ensure it fits perfectly in my bike’s battery compartment. A snug fit is essential to avoid any movement that could damage the battery or the bike.
- Weight
The weight of the battery also mattered to me, as a lighter battery can improve handling. However, I prioritized performance over weight, ensuring I chose a battery that could handle the power demands of my Fatboy.
Top Brands to Consider
After researching and asking fellow riders, I found a few brands that stand out for their high torque cranking power batteries:
- Odyssey: Known for their extreme performance and reliability, Odyssey batteries are a favorite among Harley owners.
- Yuasa: A well-respected brand in the motorcycle battery world, Yuasa offers a range of high-performance batteries that fit the Fatboy.
- Shorai: If you’re looking to save weight without sacrificing power, Shorai lithium batteries might be the way to go.
Price Range
I noticed that the price of high torque cranking power batteries can vary significantly. While I found options ranging from $100 to $300, I recommend considering the performance and warranty offered. Investing a bit more upfront can save you from potential issues down the line.
Warranty and Support
I always check for warranty information before making a purchase. A good warranty reflects the manufacturer’s confidence in their product. I found batteries with warranties ranging from 1 to 5 years, which gave me added assurance.
finding the right high torque cranking power battery for my Harley Davidson Fatboy FLSTF was an eye-opening experience. By considering factors like CCA, RC, battery type, and brand reputation, I felt more confident in my choice. I hope my guide helps you on your journey to find the perfect battery for your ride!
