7 Best Motorcycle Batteries for a 2014 Street Glide That Actually Deliver

I’ve owned my 2014 Street Glide for nearly a decade now, and I’ve been through more batteries than I care to admit. Some died after one brutal winter, others left me stranded at gas stations in the middle of nowhere.

After years of trial, error, and plenty of roadside frustration, I’ve finally figured out what actually works for this specific bike. The 2014 Street Glide’s 103ci Twin Cam engine demands serious cranking power, especially if you’ve loaded up on accessories like heated grips, upgraded audio, or auxiliary lights.

I’m sharing my personal picks here—batteries I’ve either run in my own bike or watched fellow riders swear by on long tours. These aren’t generic recommendations; they’re specific models I trust to fire up reliably, whether I’m leaving for a weekend trip or pulling the bike out of winter storage.

1. Yuasa YTX20L-BS — Best OEM-Equivalent Battery for Reliability

The Yuasa YTX20L-BS is my go-to recommendation when riders ask me what is the best battery for a motorcycle that just works without drama. This is the same factory battery Harley installs in many touring models, and for good reason.

It delivers 310 cold cranking amps, which is exactly what the 2014 Street Glide needs to turn over that big Twin Cam engine reliably. I’ve personally run two of these in my bike over the years, and both lasted a solid four years before showing any weakness.

The Yuasa YTX20L-BS uses AGM (Absorbed Glass Mat) technology, meaning it’s completely maintenance-free and spill-proof. No checking water levels, no corrosion worries, no leaking acid if you take a hard turn. It handles the constant vibration from V-twin engines better than any flooded battery I’ve tried.

Installation is straightforward—it’s a direct fit with the same terminal configuration as the stock battery. The dimensions are spot-on at 6.875″ L x 3.4375″ W x 6.125″ H, so it drops right into the battery tray without any modification.

At around $130 to $150, it’s priced competitively for a premium AGM battery. You’re paying for proven reliability and a brand that’s been the OEM standard for decades. If you want zero surprises and a battery that simply does its job, the Yuasa YTX20L-BS is hard to beat.

2. Antigravity Batteries ATX20-RS — Best Lightweight Lithium Option

I’ll admit, I was skeptical about lithium batteries for touring bikes until I watched a buddy install the Antigravity ATX20-RS in his Road Glide. The weight difference is immediately noticeable—this thing weighs just 5.5 pounds compared to the 17+ pounds of a traditional AGM battery.

The ATX20-RS cranks out an impressive 680 cranking amps, nearly double what an AGM battery provides. Cold starts are noticeably faster, even in freezing weather. The built-in battery management system (BMS) protects against over-discharge, and the integrated jump-start feature has saved my friend twice when he accidentally left his key on.

Lithium batteries don’t suffer from the same voltage sag as lead-acid batteries, so your lights stay brighter and your fuel injection operates more consistently throughout the discharge cycle. For riders who’ve added significant electrical accessories, that stable voltage is a real advantage.

The downside? Price. The Antigravity ATX20-RS runs about $350 to $400, roughly three times the cost of a quality AGM battery. You’ll also want to verify your charging system outputs between 13.6V and 14.4V—most 2014 Street Glides are fine, but it’s worth checking.

In extreme cold (below 20°F), lithium batteries can be sluggish until they warm up internally, though the ATX20-RS handles cold better than most lithium options. If weight savings matter to you—maybe you’re racing, or you just want every advantage on long-distance touring—this battery delivers.

3. ThrottleX Batteries HDX20L — Best Budget AGM Battery

Not everyone wants to drop $150+ on a battery, and I completely understand that. The ThrottleX HDX20L is my pick when riders need a reliable battery brand for their motorcycle without breaking the bank.

This battery typically sells for $80 to $100, yet it still delivers 310 CCA and uses AGM construction. I’ve installed several of these in friends’ bikes over the past few years, and the performance has been solid. They fire up consistently, handle heat well, and don’t leave riders stranded.

The HDX20L is a direct fit for the 2014 Street Glide with the correct HD terminal configuration (positive on the left, negative on the right). Build quality is decent—the case is sturdy, terminals are secure, and the sealed AGM design means no maintenance headaches.

Where you notice the lower price is in longevity. Most ThrottleX batteries I’ve tracked have lasted three years with proper care, compared to four or five years for premium brands. That’s still respectable, especially considering you’re saving $50 to $70 upfront.

If you’re a casual rider who puts on 3,000 to 5,000 miles per year, or if you’re flipping bikes regularly, the ThrottleX HDX20L makes total sense. It’s a practical choice that gets the job done without premium pricing.

4. Odyssey PC545 — Best Extreme Performance Battery

The Odyssey PC545 is what I’d call a serious rider’s battery—it’s over-engineered in the best possible way. This thing pumps out 460 CCA from a relatively compact package, which is impressive power density for a lead-acid battery.

Odyssey batteries use pure virgin lead plates (99.99% pure) instead of the recycled lead most manufacturers use. The result is longer life and better performance. Odyssey claims 3 to 10 years of service life, and while that upper range seems optimistic, I’ve personally seen these batteries hit the six-year mark with regular use.

The PC545 handles deep discharge cycles better than standard AGM batteries, recovering fully even after being drained significantly. If you’ve ever accidentally left your key on overnight, you know how critical that resilience can be. It also maintains cranking power in extreme temperatures, from -40°F to 140°F.

This battery is designed for high-vibration applications, making it ideal for touring motorcycles like the Street Glide that spend hours at highway speeds. The mounting flexibility is excellent—it can be installed in virtually any position without issue.

At $200 to $250, the Odyssey PC545 is a premium investment. But if you put serious miles on your Street Glide, demand absolute reliability, or ride in harsh conditions regularly, this battery justifies its cost through sheer longevity and performance.

5. Shorai LFX21A6-BS12 — Best Compact Lithium Alternative

Shorai was one of the first brands to bring lithium iron phosphate (LiFePO4) batteries to the powersports market, and the LFX21A6-BS12 remains a solid option for Street Glide owners who want to shed weight without going ultra-premium.

This battery weighs just 3.77 pounds—less than a quarter of what a traditional AGM battery weighs. For touring riders who obsess over every pound, especially when loading up saddlebags and a tour pack, that weight savings is meaningful. The reduced unsprung weight also slightly improves handling and acceleration, though the difference is subtle.

The LFX21A6-BS12 delivers 429 pulse cranking amps, more than enough to spin the 103ci engine quickly. Shorai’s proprietary cell technology provides excellent power-to-weight ratio and maintains voltage better throughout the discharge curve than lead-acid batteries.

One quirk with Shorai batteries: they don’t play well with traditional battery tenders. You’ll need to either use Shorai’s own BMS01 charger or ensure your existing tender has a lithium-compatible mode. That’s an extra $50 to $100 expense if you don’t already have the right charging equipment.

The LFX21A6-BS12 typically costs $250 to $300, positioning it between premium AGM and top-tier lithium options. If weight reduction is important but you’re not ready to spend $400, this Shorai battery hits a nice middle ground.

6. Motocross PTX20L-BS — Best Value for Occasional Riders

If your Street Glide sits more than it rides—maybe it’s a fair-weather bike or you’re working through a busy season—the Motocross PTX20L-BS offers surprisingly good value. I’m talking $60 to $80 for a functional AGM battery that won’t embarrass you.

This battery delivers 270 CCA, which is technically below Harley’s 310 CCA recommendation. In practice, I’ve found it starts the 2014 Street Glide just fine in moderate weather (above 40°F). If you ride in consistently cold climates, you’ll want something with more cranking power. But for spring-through-fall riding in temperate regions, it gets the job done.

The PTX20L-BS comes pre-filled and charged, so installation is simple. It’s a direct fit with the correct terminal layout. Build quality is basic but adequate—the case isn’t as robust as premium brands, and the terminals are a bit smaller, but they hold connections securely.

Battery life is the expected tradeoff. Most riders I know get two to three years from Motocross batteries with proper maintenance. That’s shorter than premium options, but when you factor in the lower upfront cost, the value equation still works for some situations.

This isn’t the battery I’d choose for cross-country touring or if my Street Glide is my daily rider. But for occasional weekend cruises or as a budget replacement when cash is tight, the Motocross PTX20L-BS is a practical option.

7. Scorpion Stinger YTX20L — Best for Accessory-Heavy Builds

My Street Glide has more electrical accessories than I probably need—upgraded stereo, heated grips, heated seat, auxiliary lights, GPS, phone charger, and dashcam. That electrical load demands a battery with serious reserve capacity, which is where the Scorpion Stinger YTX20L excels.

This battery provides 350 CCA and exceptionally high reserve capacity, meaning it can power accessories for longer periods without the engine running. The AGM construction is spill-proof and maintenance-free, with excellent vibration resistance for long-distance touring.

Scorpion uses thicker lead plates than many competitors, which translates to longer service life and better deep-cycle performance. If you’re the type who sits in parking lots with the radio on between legs of a ride, that deep-cycle capability matters more than you’d think.

The Stinger YTX20L fits perfectly in the 2014 Street Glide’s battery tray and comes with both automotive-style and powersports-style terminal adapters. I appreciate that flexibility—it means you can use standard battery terminals or the threaded studs, depending on your cable setup.

At around $140 to $160, it’s priced slightly above budget AGM batteries but below premium options. For riders who’ve invested heavily in accessories and need a battery that can handle the electrical load without constant voltage drops, the Scorpion Stinger YTX20L is purpose-built for the job.

What I’ve Learned About Street Glide Batteries

After years of testing different batteries in my 2014 Street Glide and talking with dozens of other touring riders, a few patterns have become clear. AGM batteries consistently outperform traditional flooded batteries in every category that matters for touring bikes—longevity, vibration resistance, maintenance, and reliability.

Lithium batteries are tempting for their weight savings and cranking power, but they’re not necessary for most riders. Unless you’re chasing every possible performance advantage or regularly riding in extreme conditions, a quality AGM battery like the Yuasa or Odyssey will serve you better for the money.

Cold cranking amps matter more than peak amps or reserve capacity for starting reliability. Your 2014 Street Glide needs at least 310 CCA, and going slightly higher (350+ CCA) provides meaningful insurance against cold weather starts and aging battery performance.

Battery Maintenance Makes the Difference

The best battery in the world won’t last if you neglect basic maintenance. I learned this the hard way when I killed an expensive Yuasa battery by leaving my Street Glide sitting for four months without a tender.

Investing in a quality battery charger is just as important as buying a good battery. A smart tender keeps your battery at optimal charge during storage without overcharging. I use a CTEK Multi US 3300, and it’s added at least a year to every battery I’ve owned since.

Check your charging system voltage regularly. Your 2014 Street Glide should output 13.5 to 14.5 volts at 2,000 RPM. Lower voltage means your battery isn’t charging properly; higher voltage can damage AGM batteries. I check mine twice a year with a basic multimeter—takes five minutes and prevents expensive problems.

Installation Tips from the Road

Installing a battery in a 2014 Street Glide is straightforward, but a few tips make it easier. Always disconnect the negative cable first and reconnect it last to avoid shorts. Clean the battery tray and cable terminals with a wire brush before installing the new battery—corrosion resistance starts with clean connections.

Apply a thin layer of dielectric grease to the terminals after installation. This prevents corrosion and makes future removal easier. Don’t overtighten the terminal bolts; snug is sufficient, and overtightening can crack the battery case or damage the terminals.

After installation, I always take a 20-minute ride to let the charging system top off the battery. Then I check the voltage again the next morning before starting the bike. If it’s below 12.6 volts, something’s wrong with either the battery or the charging system.

When to Replace vs. Recharge

Not every dead battery needs replacement. If your battery voltage drops below 12.4 volts but the battery is less than three years old, try a proper recharge first. Use a quality smart charger, not a quick “jump” charge, and let it charge slowly over several hours.

If the battery won’t hold a charge above 12.6 volts after a full charge cycle, or if it drops below 12.4 volts within 24 hours without use, it’s time for replacement. Also replace immediately if you see any physical damage, swelling, or leaking—these are safety issues, not performance issues.

I’ve also learned that batteries from the same brand can vary. I’ve had Yuasa batteries last five years and others die after three. Manufacturing date matters (check the date code), and storage conditions before sale affect longevity. Buy from reputable dealers with high turnover to ensure you’re getting fresh stock.

Final Thoughts on Choosing Your Battery

The right battery for your 2014 Street Glide depends on how you ride, where you ride, and what you’ve done to the bike. If you’re running a stock electrical system and ride mostly in moderate weather, a solid AGM battery like the Yuasa YTX20L-BS or ThrottleX HDX20L will serve you well for years.

If you’ve added serious electrical accessories or demand maximum reliability for long-distance touring, step up to the Odyssey PC545 or Scorpion Stinger YTX20L. The extra upfront cost disappears when you’re 500 miles from home and the bike fires up instantly.

Lithium batteries like the Antigravity ATX20-RS or Shorai LFX21A6-BS12 make sense for weight-conscious riders or those who want the absolute best cranking performance. Just factor in the higher cost and the need for lithium-compatible charging equipment.

Whatever battery you choose, treat it right. Use a tender during storage, keep connections clean, monitor your charging system, and don’t let the battery sit discharged for extended periods. Following these simple practices, even a budget battery will outperform a premium battery that’s neglected.

I’ve been through enough batteries in my Street Glide to know what works and what doesn’t. The batteries on this list represent the options I trust—either in my own bike or in the bikes of riders I respect. Choose based on your priorities, install it properly, maintain it consistently, and you’ll have reliable starts for years to come.
