Buying Guide for 2009 Heritage Softail Battery 65711

Understanding the Battery Requirements

When I first looked for a battery for my 2009 Heritage Softail, I realized it’s crucial to know the exact specifications needed. The 65711 battery is designed to fit this model, but I made sure to check the voltage, cold cranking amps (CCA), and dimensions to match the original battery. Ensuring compatibility helps avoid installation issues and performance problems.

Choosing the Right Battery Type

I found that there are mainly two types of batteries suitable for the 2009 Heritage Softail: traditional lead-acid and maintenance-free AGM (Absorbed Glass Mat). Each has its pros and cons. Lead-acid batteries are generally more affordable but require regular maintenance. AGM batteries tend to last longer and are more resistant to vibration, which is perfect for a motorcycle like the Heritage Softail.

Considering Cold Cranking Amps (CCA)

Starting power is important, especially in colder climates. I paid close attention to the CCA rating of the battery. The higher the CCA, the better the battery can start the engine in low temperatures. For my bike, I looked for a battery with a CCA rating that met or exceeded the factory specifications to ensure reliable starts every time.

Battery Size and Fitment

The physical size of the battery is a detail I didn’t overlook. The 2009 Heritage Softail requires a battery that fits snugly into its compartment. I measured the original battery and compared it to potential replacements. A battery that’s too large or too small can cause installation headaches or damage over time.

Maintenance and Longevity

I considered how much effort I was willing to put into battery upkeep. Some batteries need regular topping up with distilled water, while others are sealed and maintenance-free. For convenience, I leaned towards maintenance-free options but made sure to keep the terminals clean and check for corrosion to extend battery life.

Price vs. Performance

Balancing cost and quality was another key factor. While I wasn’t looking for the cheapest battery, I also didn’t want to overspend on features I didn’t need. I compared warranties, brand reputations, and customer reviews to find a battery that provided good value for my 2009 Heritage Softail.

Installation Tips

Installing the battery properly is essential for safety and performance. I made sure to disconnect the negative terminal first, then the positive, and reversed the order when installing the new battery. Tightening the terminals securely and checking the connections helped prevent electrical issues down the road.

Final Thoughts

Buying a battery for my 2009 Heritage Softail was a straightforward process once I understood what to look for. By focusing on compatibility, battery type, CCA rating, size, and maintenance, I ensured my bike starts reliably and runs smoothly. Taking the time to research and choose the right battery made all the difference in my riding experience.
