Customer Review: “I took a chance and ordered this battery, at the time hoping I wouldn\’t have to also fork out $200 on a new primary (crank) battery. The small battery has to come out first; the crank battery does not have room to come out unless you pull the auxiliary first.

Complete Buying Guide for Best Motorcycle Battery For Harley Davidson
Essential Factors We Consider
Choosing the best motorcycle battery for your Harley Davidson involves more than just picking a brand. You need to consider several key factors to ensure compatibility, performance, and longevity. First, always check your Harley’s manual for the recommended battery type, dimensions, cold cranking amps (CCA), and amp-hour (Ah) rating. AGM (Absorbed Glass Mat) batteries are a popular choice for Harleys due to their spill-proof design, vibration resistance, and deep cycle capabilities. Lithium-ion batteries are also gaining popularity for their lighter weight and extended lifespan, though they come at a higher price point. Ensure the terminal configuration (positive and negative pole placement) matches your bike’s wiring. A snug fit is crucial to prevent movement and potential damage.
Budget Planning
Your budget will significantly influence your choice. While it might be tempting to opt for the cheapest option, remember that a battery is a critical component for your Harley’s operation and safety. Investing in a quality battery can save you from inconvenient breakdowns and costly repairs down the line. Generally, traditional lead-acid batteries are the most affordable, followed by AGM batteries, and then premium lithium-ion batteries. Consider the battery’s warranty and expected lifespan as part of its overall value. Sometimes, paying a little more upfront for a reputable brand with a good warranty can lead to long-term savings.
Final Thoughts
Ultimately, the best motorcycle battery for your Harley Davidson is one that reliably starts your engine, fits perfectly, and meets your riding needs and budget. Prioritize CCA for strong starting power, especially if you ride in colder climates. Look for a maintenance-free design for convenience. Always double-check specifications against your Harley’s requirements. By considering these factors, you’ll be well-equipped to select a battery that keeps your Harley running strong and ensures every ride is an enjoyable one.
Frequently Asked Questions
Q: What type of battery is best for a Harley Davidson?
A: AGM (Absorbed Glass Mat) batteries are highly recommended for Harley Davidson motorcycles. They offer excellent vibration resistance, a sealed, maintenance-free design, and robust starting power. Lithium-ion batteries are also a great, albeit more expensive, option for their light weight and longer lifespan.
Q: How often should I replace my Harley Davidson motorcycle battery?
A: Typically, a Harley Davidson motorcycle battery lasts between 2 to 5 years, depending on factors like usage, maintenance, climate, and charging habits. Regular charging and proper storage during off-seasons can help extend its life. It’s recommended to test your battery annually after the second year.
Q: What are Cold Cranking Amps (CCA) and why are they important for a Harley battery?
A: Cold Cranking Amps (CCA) measure a battery’s ability to start an engine in cold temperatures. A higher CCA rating means more starting power in cold conditions. Harleys, especially those with larger engines, require a good amount of CCA to turn over, making it a critical specification to match or exceed your manufacturer’s recommendation.
Q: Can I use a regular car battery charger for my Harley Davidson motorcycle battery?
A: It’s generally not recommended to use a standard car battery charger for your motorcycle battery, especially for AGM or lithium types. Car chargers can deliver too much amperage, potentially overcharging and damaging a motorcycle battery. Always use a charger specifically designed for motorcycles, preferably a smart charger or a trickle charger, which adjusts charging rates for optimal battery health.
Q: What are the signs that my Harley Davidson battery needs replacing?
A: Common signs include slow engine cranking, dimming headlights when the engine is off, the battery not holding a charge for long, frequent need for jump-starts, or a swollen battery case. If your bike struggles to start, especially after being parked for a while, it’s definitely time to check your battery.
Choosing the right battery is crucial for the heart of your Harley Davidson. Our guide and top recommendations aim to simplify your decision, ensuring you pick a reliable power source that stands up to the demands of your ride.
