Like a standard car or truck, motorcycles also utilize a battery to start up and control on-board electronics. That includes your Harley Davidson, which likely came with a battery pre-installed. But in time, that battery has likely worn down and may be on its last legs. Now is a great time for you to consider replacing that battery so that your Harley is always ready to hit the road.

To do that, though, you’ll need to procure a replacement battery that is fully compatible with your bike’s make and model. While this may be as easy as speaking with your preferred mechanic, you may find that their service fees are more than you are willing to pay. Instead, you could always procure your own replacement Harley battery and perform this quick maintenance on your own.

This guide will help you complete both of those steps in no time at all. Using my in-depth reviews, you’ll be able to learn about the best features and specifications provided by some of the market’s most popular Harley replacement batteries.

You’ll also be able to find resources that will help you understand the battery replacement process in minutes. Even if you don’t need a Harley replacement battery just yet, this guide can help you understand what to look for in a high-performance battery when that time comes.

Why Invest in a Harley Davidson Battery?

If you drive a Harley Davidson, you’ll eventually need to buy a replacement battery. Like a car battery, these units wear down over time and eventually fail to keep a charge.

As such, it’s always good to be prepared by having a backup on hand. Not just any random battery will do, of course. You’ll need to invest in a battery unit that is fully compatible for safe use with your particular Harley Davidson model.


Harley Davidson Batteries - Buying Guide Specs

Harley Battery Type

While shopping for a replacement battery for your Harley, you should always take some time to compare different battery types. Currently, you’ll be able to find a selection of sealed and rechargeable batteries on the market. These batteries may also incorporate different methods of holding a charge, including lithium-ion, lead acid, or AGM technologies.

Generally speaking, rechargeable batteries are a better investment because they can last longer before needing to be entirely replaced. However, they don't always handle heat or extreme cold well. As such, sealed batteries remain a viable option, though they often need to be replaced more frequently.

This video can also help you understand motorcycle battery types more efficiently.

Engine Compatibility & Battery Size

Harley Davidson replacement batteries come in several sizes, which often relates to that battery’s overall capacity. Because Harleys come in several different sizes, is it important to pick out a battery model that is compatible with your bike. To do this, measure the dimensions of your current battery and ensure that your chosen replacement is exactly the same size.

Cold Cranking Amps

On your current Harley battery, you’ll see a specification under “CCA.” This is short for “cold cranking amps,” which is a measure of how much power that battery is capable of outputting when “cold” or otherwise unutilized. In almost all cases, it is worthwhile to get a battery with as many CCA as possible. However, high CCA units often cost more, so you can usually make do with a replacement battery that provides just as many CCA as your old battery.

Life Span & Expiration Date

Like conventional batteries, Harley replacement batteries are not rated to last forever. Most are only rated to operate reliably for a certain amount of time, as measures in “amp hours.” Also, a replacement battery will not last forever, even if it has not yet been used at all. This is because many batteries will “expire” after a certain date, meaning that the chemicals within them will no longer conduct electricity optimally or at all.

Durability

Durability is absolutely vital when it comes to Harley batteries. In particular, you should look for units that are vibration-resistant. This is because vibrations from the road can cause a lessor battery to lose connectivity, which leads to inefficient operations. Along the same lines, you should be looking for durability through a battery’s construction. This may include reinforced or corrosion-resistant terminals, screws, and plates – all of which can cause a battery to fail suddenly if they are allowed to rust.

Recharge Value

If you are investing in a rechargeable battery, be sure to determine how long it takes to recharge and how many recharging cycles that a particular model can handle. While these specifications may be listed with the unit's listing, your best bet for reliable information on this front is to check customer reviews of that model. These can often highlight how long other bikers were able to use that rechargeable unit before it failed to hold a full charge.

Price & Warranty

While shopping for a replacement battery for your Harley Davidson, you should keep your eyes out for a bargain. While most Harley batteries are fairly reasonable in price, some brands have started charging up to $300 for their newest units. A reasonable price, by comparison, should fall between $100 and $150. That price should account for a warranty as well, which is important to have in case your new battery fails to perform properly or is “dead on arrival.”

Electra Glide 1997-2019, Road Glide 1998-2013, Road King 1997-2019, Street Glide 2006-2019, Tri Glide 2009-2019, Ultra Classic 1997-2019

Let’s start off strong with one of the best batteries for a Harley Davidson - THROTTLEX MX30L. As my top pick, it should be no surprise to learn that this model provides all of the best specifications, particularly those dealing with its core power and longevity. To that end, this unit outputs a full 600+ CCA when properly utilized while also lasting for up to 30 amp hours. At only around 22.5 lbs., it really shouldn’t add much extra weight to your ride, either.

Of course, one of the main reasons I love this battery is because it utilizes Absorbed Glass Mat technology. This is one of the latest innovations in this field, and the THROTTLEX MX30L makes full use of it. In fact, this battery is almost 100% spill-free and leak-free when stored in a climate-controlled environment. Similarly, this model's full-frame plate allows for a more reliable cranking rate while also preventing most incidental discharge.

This battery’s architecture is designed to replace the 66010-97A-D batteries that come standard in many Harley Davidson bikes. As such, drivers of the Electra Glide, Road King, Tri Glide, and more can count on this battery to be fully compatible. They can also expect to find it on store shelves when they need it most because this unit is widely available (though it is still cheaper to buy it online).

Pros

  • Unique Absorbed Glass Mat battery type is spill-proof and leak-proof
  • Replaces four of the most common OEM Harley battery types
  • Full frame plate provides increased cranking amps and low discharge rates

The Deka Sports Power ETX-30L is up next, though it should be at the top of the list for anyone looking for the best battery for a Harley Davidson Ultra Classic. This model’s core specifications are solid across the board, with 400 CCA output and 20 amp hour service life, both demonstrating this unit's operational quality. This unit's 10-hour reserve capacity is nothing to cough at either, particularly when this unit reaches the end of its lifespan.

This model is also built with durability in mind, as seen in its molded connections, fortified posts and stainless steel terminals. All three of these components allow this unit to stand strong against corrosion, which tends to be a problem for other models in its class. The Deka Sports Power ETX-30L‘s pressurized valve system and heat-sealed cover also go a long way towards protecting this unit’s productivity from the inside out.

Storing your Harley’s battery in the winter often feels risk. Fortunately, the Deka Sports Power ETX-30L‘s demineralized electrolyte suspension can actively prevent the kind of leaks caused by extremely cold weather. As such, you'll know that your Harley is ready to roll when spring rolls around with this battery installed.

Pros

  • Molded connections, fortified posts, and stainless steel terminals add to overall durability
  • Pressurized valve system and heat-sealed cover prevents leaks
  • Demineralized electrolyte suspension ensures reliable off-season storage

Now, I know that this model looks just like the battery I selected as my top pick. But the THROTTLEX HDX30L is slightly different, which makes it both the best battery for A Harley Davidson Road Glide and the best battery for a Harley Davidson Road King. In fact, this model earns my praise for many of the same reasons, including its utilization of Absorbed Glass Mat technology. Even its 400 CCA rating (though slightly lower) is still pretty impressive, as well.

Of course, there are a few great features packed into the THROTTLEX HDX30L that make it unique. For example, this model is equipped with stainless steel bolts that can resist corrosion from both moisture and acid. Along the same lines, this model's patented female threaded terminals do an excellent job of maintaining a connection, even on the bumpiest of roads. Those terminals are made of solid lead, too, so they won't degrade over the life of the battery.

This model’s porous microfiber separators are worth talking about as well. That’s because they effectively prevent this battery from leaking at all. As such, this “Made in the USA” battery won’t require any extra maintenance during the off-season.

Pros

  • Porous microfiber separators prevent leaks
  • Stainless steel bolts resist corrosion
  • Patented female threaded terminals provide a reliable connection that is vibration-resistant

Cons

  • Does not handle the cold well

The Harley Davidson Touring remains one of the most popular models from this classic motorcycle brand. As such, it’s no surprise that the Chrome Battery YTX30L-BS remains one of the most popular replacement batteries on the market today. Some even call it the best battery for a Harley Davidson Touring based upon its solid 385 CCA rating. But if I were to give you just one reason this model is outstanding, I would definitely endorse its sealed, corrosion-resistant ports.

Of course, there’s far more than one reason why you should buy a Chrome Battery YTX30L-BS. Another excellent reason its exterior durability, which has always been a point of pride for this brand. This is a result of its lead calcium alloy enclosure, which can stand up to hard impacts and resist vibrations reliably. Like this model’s ports, this enclosure is also corrosion-resistant without being made of thin plastic.

The Chrome Battery YTX30L-BS’ price tag comes as a major surprise, though. I’d have gladly paid over $100 for all of the value that this battery packs in. But instead, it only costs right around $80. That’s entirely affordable for any bike, regardless of their budget. Some popular online retailers even have it for cheaper if you can get it on sale.

Pros

  • Affordably priced
  • Sealed posts are fully resistant to acid corrosion
  • Lead calcium alloy exterior is durable and vibration-resistant

Cons

  • Only test for compatibility with older models

While there are several options when it comes to the best battery for a Harley Davidson Street Glide, I'd still choose the Yuasa YUAM732HL 9 times out of 10. Now, that may initially come as a surprise given that this battery’s manufacturer failed to include a compatibility list within this model’s specifications. But take my word for it when I say that this model is perfectly compatible. In fact, the 500 CCA of power it can provide your Street Glide is more than almost any other compatible battery in its price range.

Speaking of price, the Yuasa YUAM732HL will run you a relatively average price of around $130. That price doesn't appear to factor in a warranty, which is a little disappointing. However, as a tradeoff, this unit provides a reliable 32 amp hour battery life that is sure to impress. This model’s polypropylene cover and container are sure to impress as well, particularly when they block out extreme heat and cold from reaching this battery’s core.

Unlike most motorcycle batteries, which are designed for use in any number of brand's bikes, the Yuasa YUAM732HL was specifically made for the US market. As such, its durability far exceeds foreign-made competitors. This can be seen through this battery's construction, including its heavy-duty terminals and brass nuts.

Pros

  • Designed for US market for OEM replacement
  • Heavy-duty terminals and brass nuts provide added durability
  • Polypropylene cover and container provide exceptional heat and cold resistance

Cons

  • Lacks compatible Harley model list

Most models with lithium-ion compatible equipment

In recent years, advancements in lithium-ion technology has allowed it to become viable even in motorcycle batteries. As such, more and more models like the Twin Power DLFP30HL-BS-H have begun to hit the market. Of course, few of those competitors can match the Twin Power DLFP30HL-BS-H when it comes to its 625 CCA of core power. Even its voltage is a head above the rest at 12.8 volts.

According to its manufacturer, the Twin Power DLFP30HL-BS-H possesses twice the service life of traditional lead acid batteries. That may be true, but it doesn't quite excuse them charging twice as much for this particular battery. It may be considered one of the best lithium motorcycle batteries for a Harley Davidson, but that does mean they can charge around $300 for it on a regular basis. If this model didn’t also come with a 2-year warranty, I might have just passed it up for a cheaper alternative.

But with those negative aspects aside, the Twin Power DLFP30HL-BS-H really does include features unseen in most other Harley replacement batteries. This unit’s cylindrical cells are a great example, given that they provide extremely reliably output without the use of an acidic solution. This model even includes built-in charge and equalizing protection, which prevents overcharging from occurring in the first place.

Pros

  • Built-in charge and equalizing protection prevents overcharging
  • Heavy-duty terminals in stock configuration allow for quick and easy installation
  • Cylindrical cells allow for reliable output without use of acidic solutions

Cons

  • More expensive than most replacement batteries

When I say that the Weize YTX30L-BS is one of the cheapest batteries for a Harley Davidson available right now, you might be confused about why that’s something to brag about. But once you check out this battery’s specifications, you’ll immediately see why I was impressed at this model’s low price tag.

For starters, the Weize YTX30L-BS provides 385 CCA of power, which is already impressive for a cheap unit. But it also comes with a 2-year warranty, which even some models that are twice as expensive don’t include.

Also, given its price, you might assume that the Weize YTX30L-BS is built with the bare basics when it comes to battery technology. But that’s not the case, as you can see from its inclusion of Absorbed Glass Mat technology.

This feature prevents this unit from leaking in most circumstances, which adds to its overall longevity. That being said, this battery only tends to last through about 2 years of day-to-day use. So, be sure to pick up a couple for the price you’d usually pay for just one replacement Harley battery!

Pros

  • Affordable while still providing solid warranty
  • Absorbed Glass Mat technology and sealed posts prevent leaks and corrosion
  • Enclosure prevents vibration to maximize conductivity

Cons

  • Only last around 2 years at a time

Finally, we come to the Renegade RG30L-WS, which is actually rated as one of the best rechargeable batteries for a Harley Davidson motorcycle. Those high ratings often mention this model’s impressive 500+ CCAs of power, which is well above average.

Some also mention this battery’s ability to exceed its advertised cranking power cap when installed in an Electra Glide, Road Glide, Road King, Street Glide, Tri-Glide, and Ultra Classic model. However, several of those models require you to routinely remove and care for this battery, so plan accordingly when investing in a replacement.

If you do keep up with this manufacturer’s recommendations for routine maintenance, you’ll find the Renegade RG30L-WS’ service life to be longer than most. In fact, this battery can easily exceed its 1-year warranty coverage period and remain reliable for as many as 5 years. This model's impact-resistant case also plays a part in that longevity, given that it can resist the kinds of vibrations that would cause lesser batteries to lose connectivity.

I know some Harley riders are concerned about adding too much extra weight onto their ride, especially when traveling long distances. The Renegade RG30L-WS won’t be a problem on that front, even if you decide to carry a spare. At only around 21 lbs., this battery weighs as much as most in its class. Its physical dimensions are a bit slimmer, though, so it should fit comfortably in any Harley’s battery compartment.

Pros

  • Fully sealed construction prevents leaks, even with daily use
  • Impact-resistant case adds to service lifespan
  • Increase cranking power ideal for Electra Glide, Road Glide, Road King, Street Glide, Tri-Glide, and Ultra Classic models

Cons

  • Requires special care to maintain a long lifespan

Installing & Replacing a Harley Davidson Battery

Installing a new Harley Davidson battery can take a little bit of time if you’ve never replaced your own bike battery before. But that being said, with the right tools, you should be able to complete the task on your own.

It is also recommended that you read your owner's manual instructions for replacing your battery before proceeding. This can ensure that you are fully aware of the several components you’ll need to remove and move around to gain access to your Harley’s battery.


Charging a Harley Davidson Battery

If you’re new to motorcycle riding, then you may not have experience charging up your own bike’s battery. In most situations, recharging your battery manually will not be necessary, so long as your bike's motor and circuitry are properly recharging the battery while you are riding.

However, if a bike is not ridden for an extended period (such as during the winter), its battery may drain down completely. In that situation, you may need to recharge your battery using the technique demonstrated in this video.


People Also Ask (FAQs)

How long do Harley Davidson batteries last?

In most cases, a Harley’s battery life will vary depending on how often and how much you use it. If you ride at least once a week, then your bike’s battery life can extend from 3-4 years. However, if you only bike occasionally, then your bike’s battery life is likely to depreciate at a quicker rate. Also, if you store your bike in an extremely hot or cold environment, its battery life will degrade in as little as 1 year.

How can I prolong the life of my motorcycle battery?

One of the best ways to maintain your bike’s battery is by riding it regularly. This will ensure that it remains fully charged and viable when you need it. Also, always store your bike (or the battery itself, you have removed it) in a climate-controlled environment where it is not exposed to extreme heat or cold. If you do need to recharge your battery manually, avoid overcharging it as well. Overcharging damages the unit's internal components, leading to more rapid degradation of capacity.

Will a motorcycle run with dead battery?

Like with your car or truck, your motorcycle will not run if it lacks a battery or is connected to a dead battery. Because the battery powers your bike's starter, it likely won't even start up without a properly-charged battery connected.

What are the best Harley Davidson battery brands?

There are a fair number of Harley Davidson battery brands on the market today, each of which provides several models that can fit a wide variety of Harley makes and models. Some of the most popular brands include THROTTLEX, Renegade, Weize, and Deka Sports.

Does a higher CCA rating mean a better battery?

If you are comparing batteries based upon their raw power output, then yes, a higher CCA rating is preferable. However, raw power alone does not make for a good battery. Instead, you should ensure that your chosen battery is as durable as it is powerful. You should also ensure that it is built to resist leaks, which often plague high CCA batteries.


Conclusion

I’ll admit, shopping for a new battery for a Harley Davidson can feel intimidating at first. After all, there are so many options to choose from! But as you've seen, there are only a few models that are a cut above the rest. Be sure to select one of the models I've reviewed next time you need a replacement battery for your bike. You won't be disappointed!

If you’re in a rush to get back on the road, though, you should simply pick up a THROTTLEX MX30L battery. This model’s 600+ CCA rating is fantastic, making it among the top in its class for this specification. Better yet, its implementation of Absorbed Glass Mat technology allows it to almost entirely avoid leaks or spills of any kind.
