Best Battery for Harley Davidson Street Glide: 8 Worthiest Models

  1. Yuasa YUAM320BS YTX20L-BS Battery – Top Pick
  2. Chrome Pro YTX7A-BS iGel Maintenance Free Replacement Battery – Budget Choice
  3. Antigravity ATX12-HD – Premium Choice
  4. Deka Sports Power ETX-30L – Good Rated
  5. Harley FXDC – Best for Harley Davidson

Below are my detailed reviews of the most reliable Harley Street Glide battery that you can find in stores. All of them are tested for years and provide excellent performance for both average and extreme use circumstances. One of them will definitely fit your badass H-D.

1. Yuasa YUAM320BS YTX20L-BS Battery – Trusted Japanese Power Cells


Yuasa is a famous battery manufacturer that has been supplying the market with high-quality products since 1979. Before East Penn Manufacturing took them over in the mid-2000s, Yuasa was an official battery supplier of Harley Davidson. I couldn’t find the real reason for them not to prolong the contract as the brand still provides exceptional quality.

YTX20L-BS offers excellent cranking performance due to patented thin separators that let engineers install two extra plates into each cell. The only minus of their technology is that they have to ship the item dry, and you have to fill it manually. Fortunately, it’s possible to close it hermetically.

The battery has 6.87 x 3.43 x 6.12 dimensions and the K26012-3721 OEM part number. It’s an excellent solution for touring and cruising, but I’d not recommend it for sports as it’s not a pre-filled model. That’s why I cannot call it the best item, but definitely a reliable one.

  • Relatively cheap model
  • Japanese quality
  • Wide range of settings
  • Doesn’t require maintenance after the initial filling
  • Not pre-filled with acid

2. Replacement YTX7A-BS Motorcycle Battery – Best Harley Replacement Battery with Alarm

Chrome Battery is a relatively young American brand that controls several accumulator production lines to fulfill the needs of different light and heavy industries, including vehicle manufacturers. Amongst the benefits of ordering products by this manufacturer are the 18-months warranty on the entire catalog and a 30-day money-back guarantee in case something goes wrong.

YTX7A-BS is a unique AGM accumulator that’s equipped with a monochrome LCD and installation date memory. The separately-powered chipset can automatically start recording the use days and monitor the charge level and voltage.

There’s a button for capacity testing and volt monitoring. Besides, there’s an alarm that will warn you when both figures get too low. Fortunately, the system doesn’t wait for the last day and lets you know that you have to charge up when it still can be used.

You can use this accumulator to replace your old CTX7A-BA, GTX7A, PTX7A-BS, UTX7A, GTX7A-BS, M32X7A, MTX7A-BS, LTX7A-BS, MF12V7-2A, or MFA127AH, which makes it a universal solution. However, you should also make sure that 6 Amperes and 82 Watts are enough for your motorbike.

The Size of the socket should be 5.91 x 3.43 x 3.66, while the angle can be up to 90°. I recommend this battery for everything starting from mid-range city commuting style to offroad sports as it has perfect vibration and weather protection. The CCA (90-120) is comparably low, but enough for most models.

  • Built-in charge alarm and information display
  • Universal size
  • Zero-maintenance needed
  • Extended battery life
  • 18-month warranty
  • Relatively low CCA

3. Anti-Gravity Batteries AG-ATX-12-HD-RS – Powerful Lithium Battery for Harley Davidson Street Glide

Antigravity Batteries was established in 2009 with the idea of manufacturing lightweight and secure best lithium motorcycle batteries for average use and power motorsports. Their batteries don’t include acid and heavy metals, such as mercury, lead, or cadmium, so they’re much safer for the environment than conventional cells.

This accumulator offers raw power for extreme conditions, including motorsports, and can be used in both motorcycles and cars. It perfectly fits the YTX12 socket size which has 5.9 x 3.38 x 5.19 dimensions. It also has an ambidextrous design, which makes installation a bit simpler.

The CCA of this model is 480, which is enough to start any motorcycle engine as well as race cars with up to 600 horsepower, which is an astonishing power for such a compact unit. If you use your Harley for some challenging rides, this item may fulfill your needs. It’s also an awesome Harley touring battery as it can be jump-started no matter where you are.

This and other accumulator models by Antigravity are equipped with a patented Re-Start button technology. Every cell has a small restart button on the top. You can use it to jump-start your motorcycle if the battery gets drained out by your fault or other circumstances. A single press is usually enough to go even if the battery is fully discharged.

  • Built-in jump start button
  • Whopping 480 CCA
  • No heavy metals in the composition
  • Good for sports and touring
  • Lightweight design
  • Expensive power cell

5. Harley FXDC Custom – Best Street Glide Battery


If you’re a happy owner of H-D Street Glide, Dyna Super Glide, or Super Glide Custom, this high-performance accumulator is an excellent choice as it offers a considerable amount of power for a relatively low price. Power Source Batteries is a high-quality American brand with Chinese manufacturing powers. It has proven itself as a worthy power sports accumulator seller.

WPX20L-NG is an excellent choice for all Super Glide Harleys manufactured from 1992 to 2014, and it can replace a variety of OEMs. The list includes 65989-97C, 65989-97, 65989-90B, 65989-90, 65989-97A, 65989-97B, and 65989-90A. Make sure that your bike qualifies for these OEMs and measure the dimension of your old cell. The socket must be 6.88 x 3.43 x 6.12 inches to be compatible with WPX20L-LS.

Although this brand isn’t as well known as the previous ones, I like it for the perfect performance on my 2003 100s Anniversary Dyna Low Rider (FXDL). It’s a reliable unit with a 1-year warranty, and it’s good for daily rides and touring.

  • Relatively cheap

Caltric is a popular aftermarket part supplier and one of the best accumulator manufacturers around. The brand offers relatively low prices and reliable performance. My Ytx20L-Bs came almost fully charged and pre-filled with acid.

Due to the AGM technology, leakages are impossible unless your item is damaged. It’s a nice mount-and-go solution with 6 7/8″ x 3 7/16″ x 6 1/8″ dimensions and perfect compatibility with 65989-97, 65989-97C, 65989-97A, and 65989-97B.

The item offers a fair CCA 270, 12V, and 18Ah. Of course, the Ah will be a bit lower after shipping, but you can easily boost it with the best battery tender. The package also includes replacement bolts made of anti-corrosion metal, so it’s easy to install and requires only rare cleanups.

  • Excellent AGM performance

Types of Harley Davidson Batteries for Street Glide


Harleys can be stocked with batteries of different types, depending on the year of manufacturing and particular model specifications. You should know the difference between the main types to be able to make the right choice.

Lead-Acid Batteries

These batteries have several common names, including conventional, wet cell, and flooded cell batteries. The first distinguishing element that you can see is the plastic stoppers on the top panel. In most cases, Harleys are equipped with 12-volt units that have 6 stoppers. They also have a white plastic casing.

These batteries include electrolytes covered in liquid acid. This type requires regular level control and must be topped up with technical distilled water (not drinking water!). The identification numbers of these units usually include the letters YB, CB, or GB.

Sealed Batteries

Also known as maintenance-free and dry-cell batteries, these units have electrolytes stored in the low-moisture paste, and they’re sealed hermetically. You don’t have to remove the upper lid and check the levels. The reference numbers for such batteries usually include the letters CTX, GTX, and YTX.

Gel-Filled Batteries

Gel-acid units usually have black casings without ribs and black, gray, or blue top lids. Similarly to sealed units, gel-acid batteries are non-refillable. They’re filled with gel acid that lets engineers place these power cells at an angle or on their sides. If you have something like this in your Harley, you should use only gel-filled accumulators.

Pure Lead Batteries

These power units offer exceptional performance, and extra longevity, which makes them perfect for vehicles stuffed with high-consuming electronics. Such units provide 100% leak protection and usually last up to 3 times longer than average conventional models.

Lithium Iron Phosphate

LiFePO4 accumulators have extremely-low self-discharge speeds, which makes them a perfect choice for occasional riders who don’t want to buy a charger. If you choose this technology, you have to check the voltage only once per 3 months.


This technology has been created for exploitation in heavy weather conditions and under high vibrations. As a result, it’s a perfect option for off-road sports and sockets with up to 90° tilt. It also offers high CCA and doesn’t require maintenance.

Things to Consider Before Buying Harley Davidson Battery

Choosing an accumulator for your Harley, you should take several factors into account. First of all, you should know how you will use your bike and what weather conditions are there in your area. Next, consider the characteristics given below.

Battery Size

This point is simple but crucial. You have to buy a battery that has the same dimensions as your old cell. Otherwise, it might not fit. If you have a bike manufactured in the 2000s, I’m 100% sure that it won’t fit!


Purchasing the item with proper polarity means a lot as you should be able to connect the cables without difficulties. The wrong polarity means connection problems almost in all cases, so be attentive.

Starting Power or CCA


CCA (Cold Cranking Amps) determines the starting power of the power cell. The CCA number indicated how many amperes an accumulator can give away every 30 seconds. Accumulators with higher CCA have a better starting ability and provide faster ignition. Always compare the CCA ability before Ah.


Do you still feel that you know not everything about motorcycle batteries for Harley? You should then read the answers to the most frequently asked questions that I’ve prepared for you.

What is a lifespan of a Harley battery?

Based on my own experience, official H-D measurements, and the reports of other bike owners from the most reliable forums, the average lifespan of Harley Davidson batteries can be from 3 to 5 years. The actual longevity depends on different factors, including:

  • maintenance quality – you should follow battery life maintenance recommendations to prolong its life and make sure if all the electrified parts of your bike run properly;
  • presence/absence of manufacturing defects – even top brands cannot ensure 100% quality;
  • usage conditions – the climate in your region and the exploitation heaviness can affect battery life significantly.

How can I prolong the life of my Harley battery?

Fortunately, there are several ways to prolong your battery’s life. Here are the methods that I apply:

  1. Create a Maintenance schedule – did you know that you can follow a few simple maintenance steps? First of all, you should inspect the terminals for signs of corrosion. Remove them with a wire brush asap. Next, check the level of electrolytes and add some distilled water if needed. Finally, purchase a tester to monitor your battery health over time.
  2. Charge it up – if you ride at least 3 days per week, the alternator will recharge the battery while you drive. If the pauses between rides last more than 5 days, I recommend investing in a compatible battery charger and using it regularly.
  3. Use only proper battery models to avoid power conflicts in the system.
    Avoid harsh temperature changes and don’t store your batteries in a too-cold garage as low temperatures discharge batteries when they’re not in use.

Who makes Harley batteries?


Harley batteries have been manufactured by the Deka – East Penn Manufacturing company since the mid-2000s. The company is famous for having one of the lowest defect rates in the industry. Deka has a full-cycle manufacturing line, so they control the quality of each component from the bottom up. The company is accredited with ISO 9001 and ISO/TS 16949.

How to change the battery for Harley?

If the battery on your H-D is rechargeable, you can use a battery charger to keep it charged to the full when you’re not riding. If you ride daily, the bike’s alternator should do the work perfectly well too. Besides, you can apply for a certified battery tender. This device can monitor the charge and maintain it for extended periods by switching between modes and keeping the charge on a high level.


Now you’re ready to shop and purchase the best Harley Davidson Street Glide battery replacement for your purposes. And, please, don’t forget to analyze the performance quality and longevity of your old battery. Sometimes even high-quality batteries drain out too fast as your vehicle consumes too much energy or has a significant disbalance in the power circuit.

If you think that your old unit has been discharged too early, take your two-wheeler to an experienced master who will be able to detect the malfunction in the circuit. The systems of modern Harleys are much more complicated than they used to be, so homebrew diagnostics can be resultless if you’re not a pro-level mechanic.

When the job is done, get the best Harley replacement battery and enjoy another 4-5 years of riding without energy supply issues.
