    Benefits of a Harley Battery

    • Reliability. When you have a high-quality battery in your bike, then you can rely on it to run as expected. This means your bike will start up when you put in the key and hit the button. 
    • Increased power. Having the right battery in your bike means you have plenty of power to not only start and run your bike but also power other bike accessories and your personal technology. 
    • Saves money. A high-quality battery will last for several years. This will save you money by not having to replace your battery as often. It will also protect your other electronics from malfunctioning due to the improper supply of power. 

    Types of Harley Batteries

    Absorbed Glass Mat Battery

    An Absorbed Glass Mat (AGM) battery is one of several types of lead-acid batteries on the market. This is a sealed battery that is maintenance-free and spill-proof. They also have better vibration resistance than traditional batteries because the fluid inside is more stable, thanks to the fiberglass mats and gel-like consistency. 

    Lithium-Ion Battery

    Lithium batteries tend to be more expensive but can be well worth the investment. They have much longer lives, and you can also find versions that are rechargeable. If weight is a concern for you, then lithium is ideal because they’re noticeably lighter and smaller than other options. Harley doesn’t use lithium-ion batteries for OEM applications, but other motorcycle companies do, like Ducati. 

    Flooded Lead-Acid Battery

    This is the most traditional type of battery. They need to be treated with care because they can spill battery acid and require regular maintenance. As the battery discharges, a chemical reaction happens, and water is expelled. This means you’ll need to regularly refill the battery with water to ensure proper charging and operation. 

    Top Brands

    GS Yuasa

    Founded in 2004, Yuasa is a market leader in producing lead-acid batteries for cars and motorcycles. Headquartered in Japan, its batteries are sold worldwide and used as a replacement battery when the original battery dies. Try the Yuasa YUAM72Z14 Lead Acid Battery on your bike. 

    ThrottleX

    Despite only being founded a few years ago, ThrottleX batteries are quickly making a name for themselves. The founders formed their own battery company in hopes of filling in gaps in the market for motorcycle and ATV batteries. The company focuses on tailoring batteries to fit your ride style and budget. Try the ThrottleX AGM Power Sport Battery and see the difference for yourself. 

    Chrome Battery

    For over 25 years, Chrome Battery’s team has focused on creating a high-quality buying experience to consistently exceed their customer’s expectations. Located in Carmel, Ind., the company distributes its batteries throughout the United States, Puerto Rico, and Guam. Try out the YTX12-BS iGel Battery.

    Harley Battery Pricing

    • Under $100: These are affordable batteries, but you’ll need to be careful. Some batteries in this price range are a great deal, while others severely lack in quality. Stick to reputable brands with a history of quality. 
    • $100 to $150: Most decent quality batteries fall in this range. They will have recent manufacture dates and high-quality materials used for production. The exact price will depend on the brand, size, and power. 
    • $150 to $300: Batteries in this range tend to be OEM batteries. They may or may not be of high quality when it comes to the materials used. They should have a recent manufacture date, but you should still check. You’re mostly paying for the branding of the motorcycle manufacturer. 

    Key Features

    Engine Compatibility

    The bigger and more powerful your Harley engine is, the bigger and more powerful your battery will need to be. So, the best battery for the touring Harley Davidson models is going to be larger. This would include the Electra Glide, Road Glide, Road King, Ultra Classic, and Street Glide. Smaller bikes like the Street 500 or 750 won’t need as much starting power. 

    Expiration Date

    Batteries are only good for so long, and they have expiration dates that let you know their expected useful life. If you find a battery that sounds like too good of a deal, the expiration date is probably soon or already expired. It’s best to find a battery that is not more than 6 months old. 

    Voltage

    You’ll probably want your replacement battery to be a 12-volt battery. This is the standard voltage for full-sized motorcycles. Bikes on the smallest end of the spectrum may be able to get away with a 6-volt battery. If you’re unsure of the voltage you need, look at your current battery, and it’ll tell you. Using a battery with the wrong voltage will cause your operating systems to malfunction. 

    Other Considerations

    • Cold Cranking Amps. This is the number of amps the battery can deliver smoothly when the temperature drops. What it means for you is the amount of power the battery can reliably deliver when you start your engine. If the battery can’t produce enough cold-cranking amps, then you won’t be able to start your bike. 
    • Size. Because motorcycles pack a lot of mechanics into a small space, there is often a very specific space for the battery. Just because you found one with the right amount of power doesn’t mean that it will fit your bike. You need to know the dimensions of the battery compartment to ensure your chosen battery will fit. 
    • Lifespan and durability. Consider the type of riding you do and the climate you live in when looking at the battery’s lifespan. If you live in a warmer climate or tend to take short trips, then you’ll want to choose a battery with a longer lifespan. Short trips don’t give the alternator enough time to recharge the battery. High temperatures tend to discharge a battery faster than cooler temperatures. You can extend your battery’s life by hooking it up to a battery tender when not in use.

    Tips

    • Batteries do not have a universal fitment. You have to make sure you have the right size so it will fit into your bike’s battery compartment.
    • The weather conditions where you live should determine the type of battery you will buy. There are some batteries best suited for hot weather, while others are best suited for cold weather. There are also batteries for any weather condition.
    • If a battery stays for a long time without charge, it may discharge completely and no longer be usable. Ensure you keep your battery charged.
