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. 

Energizer 

You might know the name from your double-A batteries, but this Missouri-based electronics powerhouse has evolved a lot since its inception in 1896. Operating on the international market, Energizer is one of the world’s biggest names in the battery business. It supplies everything from rechargeable flashlight batteries to the Energizer Motorcycle Battery, a great way to keep your Harley running smoothly.

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. 

Best Harley Battery Reviews & Recommendations 2021

Best Overall
Energizer TX20HL Motorcycle Battery

Equipping your Harley with 310 cold cranking amps, the Energizer TX20HL Motorcycle Battery uses lead acid technology to run smoothly and reliably. It features a sealed design, eliminating the need to top it off with water. Instead, the high-grade absorbent glass mat (AGM) tech works together with the acid solution to keep the battery working for longer. Gone are the days of batteries losing efficacy with each recharge, the glass mats stabilize the electrical current and keep it in good condition for longer. This spill proof design rings in at just under seven inches long and weighs in at 14 pounds. Fitting specific Harley models, it is also compatible with off-road vehicles like ATVs. Operating on 12 volts with 18 ampere-hours, it’s a reliable selection that makes a quality replacement for your old Harley battery. One note on this battery is that because of the AGM tech used in construction, it is vulnerable to issues with overcharging. As long as you take care of the battery and don’t flow a surge of electricity into it, this battery can last for quite some time

Best Value
Chrome Battery Replacement YTX7A-BS Motorcycle Battery

This is an affordable yet high-quality battery. It’s sealed and uses AGM technology to power your motorcycle. The battery comes fully charged and ready for use. There is a patented sealed post design that prevents corrosion and extends the overall life of the battery. There’s a digital display to make monitoring your battery’s status and power output simple.  This battery doesn’t hold a charge for very long, so you’ll need to make a separate purchase of a battery tender to keep your battery fully charged and ready for use. There is also a risk of the sealed system leaking battery acid while in transit.

Best Structural Integrity
Yuasa YTX20L-BS Battery

If you want a battery that uses modern innovations to prevent premature wear, the Yuasa YTX20L-BS Battery might be the perfect answer. This 12-volt battery rings in at 6.87 by 3.43 by 6.12 inches, fitting multiple kinds of vehicles, including several Harleys. It touts a decent 270 cold cranking amps and an entirely spill-proof design, making it ideal for rougher roads. The sealed design eliminates the need for maintenance, so your only focus is the road. It uses AGM mats, separators that facilitate the proper flow of the electrical current. It prevents spills and adds to the lifespan of the battery. Where this model really stands out is its special lead-calcium blend. This tech is built to hold its structural integrity on a molecular level for three times as long as the standard formula on the market. Triple the lifespan capacity? Now that earns a spot on our list. A couple of issues to keep in mind are compatibility and weight. This battery won’t necessarily fit with all Harleys, though at under 7 inches long, it fits most. It is, however, a fairly heavy item; which, on a small scale, impacts your fuel efficiency. For the value of its sturdy construction, though, the trade-off for weight is worth it. 

Premium Pick
Antigravity Batteries Lithium-Ion Battery

The Antigravity Batteries Lithium-Ion Battery uses proven technology to give your Harley an extra edge on the road. Extremely lightweight, it’s a little over 2 pounds, and one of the smaller batteries on the market. Ringing in at 4.5 by 3.25 by 4.25 inches, it might come in a small package, but it packs a real punch. Providing up to 360 cold-cranking amps, this battery is built to speed up the turnover process, getting you on the road sooner and with less hassle. Inside the battery is a strong lithium solution, supplying 12.8 volts of electrical capacity. Coming with an adhesive foam structure for simplified installation, this battery fits the vast majority of Harleys on the market. Featuring brass terminals, whether you’re charging or using the battery, its controls are user-friendly and its lightweight design gives it a special edge.  It’s worth noting that if you aren’t going to be using it every day, the battery may lose charge (as most do if left unattended for extended periods). Lithium-ion batteries work well with battery maintainers or trickle chargers to prevent any issues while the bike’s parked.

Honorable Mention
Zipp Battery High-Performance Motorcycle Battery

Constructed by CB Chromebattery, the Zipp Battery High-Performance Motorcycle Battery is compact, lightweight, and easy to handle. Designed to work with either ATVs or motorcycles, it runs on 12 volts and is shorter than 5 inches on its longest side. At under 5 pounds and with easy-to-identify electrodes, it touts an intuitive design that’s ideal for riders of all experience levels. It features absorption glass mat technology where the fibers contribute to the surface area inside the tube battery. It prevents flooding and goes a long way to avoiding spills. With a unique design, its sealed posts help prevent rust and corrosion. Both the interior and exterior design are structured to optimize its lifespan and performance abilities, making it well-deserving of this honorable mention. An important factor to consider is that this battery has a vehicle-specific design, meaning it won’t necessarily work with every motorcycle on the market. Check that it fits before you commit. That said, provided your Harley can work with it, this battery is a solid investment.

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.
