7 Best Rated Motorcycle Batteries for Harley Davidson 2012 Touring Models

I’ve owned my 2012 Road Glide for over a decade now, and I’ve learned the hard way that not all batteries are created equal. There’s nothing worse than turning the key on a perfect riding day only to hear that dreaded clicking sound.

After testing numerous batteries over the years and talking with fellow Touring riders, I’ve put together this guide to help you choose the right power source for your 2012 Harley Touring model. Whether you’re riding a Road King, Street Glide, or Ultra Limited, these batteries have proven themselves reliable.

1. Yuasa YTX20L-BS — Best Overall AGM Battery

I’ve run the Yuasa YTX20L-BS in multiple Touring bikes, and it’s earned its reputation as the gold standard. This AGM battery delivers 270 cold cranking amps, which is more than sufficient for the Twin Cam 103 engine in 2012 Touring models.

What impressed me most is the consistency. Even after three Wisconsin winters, my Yuasa cranked strong every spring. The sealed maintenance-free design means I never worry about acid levels or corrosion issues that plagued older wet-cell batteries.

The Yuasa YTX20L-BS comes factory-activated with acid already installed, so installation takes minutes. I appreciate that it’s spill-proof and can be mounted in any position, though I keep mine upright in the standard battery tray.

Real-World Performance

In my testing, this battery maintained voltage excellently even with heated grips and auxiliary lights running. The 18 amp-hour capacity gives me plenty of reserve power for accessories, which matters on long rides when I’m running GPS, phone charger, and heated gear simultaneously.

At around $120-140, it’s not the cheapest option, but I consider it the best value when you factor in reliability and longevity. If you’re looking for a traditional best motorcycle battery for harley davidson, this is my top recommendation.

2. Antigravity ATX20-RS — Best Lithium Battery

After hearing lithium battery evangelists rave for years, I finally tried the Antigravity ATX20-RS in my 2012 Road Glide. The weight difference alone converted me — this battery weighs just 5.2 pounds compared to the 16+ pounds of traditional AGM batteries.

The real magic is in the built-in Battery Management System. This intelligent system monitors cell voltage, prevents overcharging, and even allows the battery to restart itself after complete discharge. I accidentally left my key on overnight once, and the Re-Start function brought it back to life.

With 480 cranking amps, the Antigravity spins my engine noticeably faster than any AGM I’ve used. Cold starts are instantaneous, even in freezing temperatures. The self-balancing cells mean I don’t need to worry about maintaining perfect charge levels.

Worth the Premium Price?

At $300-350, this battery costs significantly more than AGM alternatives. However, I justify the expense through longevity — lithium batteries typically last twice as long as AGM. The weight savings matter for performance riding, and the faster cranking reduces starter wear.

For riders serious about the best lithium motorcycle battery for harley davidson, the Antigravity delivers on every promise. Just make sure your charging system is lithium-compatible (2012 Touring models are fine with proper charger settings).

3. Odyssey PC680 — Best for Custom Applications

I’ve installed the Odyssey PC680 in three different custom builds, and it’s my go-to for modified Touring bikes. While slightly smaller than stock batteries, it delivers an impressive 520 cold cranking amps and fits beautifully in custom battery boxes or relocated mounts.

The pure lead plates give this AGM battery exceptional longevity. Odyssey claims 3-10 year service life, and I’ve personally gotten six years from one in a bike that sees regular use. The deep-cycle capability means I can run it down further without damage — crucial when I’m running stereo systems at bike nights.

What sets the PC680 apart is its ability to be charged quickly and repeatedly. I can fully recharge it in about 4 hours with a proper charger, compared to 8+ hours for conventional batteries.

Installation Considerations

The PC680 measures slightly different from stock (7.17″ x 3.03″ x 6.57″), so test-fit before ordering. I’ve used foam padding or custom brackets to secure it properly. The brass terminal posts are more robust than typical lead posts, reducing connection issues over time.

At $180-220, it sits between budget AGM and premium lithium options. For custom touring builds where what is the best battery for a harley davidson motorcycle depends on specific modifications, this is my answer.

4. ThrottleX HDX30L — Best Budget AGM Option

Not everyone needs premium batteries, and the ThrottleX HDX30L proves you don’t have to spend $150+ for reliable performance. I installed one in my winter beater Road King, and it’s exceeded expectations for three seasons running.

This AGM battery delivers 400 cold cranking amps — higher than stock specifications — and uses absorbed glass mat technology for spill-proof operation. The 30 amp-hour rating gives solid reserve capacity for accessories without breaking the bank.

I appreciate that ThrottleX ships their batteries fully charged and ready to install. The high-impact ABS case has survived some pretty rough handling in my garage, and the sealed construction means zero maintenance beyond keeping terminals clean.

Where It Compromises

At $80-100, corners are cut somewhere. The lifespan averages 3-4 years versus 4-5+ for premium AGM batteries. I’ve noticed slightly slower cranking compared to Yuasa, particularly when temperatures drop below 20°F.

For riders on a budget or those who don’t keep bikes long-term, this is solid value. It’s also my recommendation for bikes that sit unused for months — I’d rather replace an $85 battery than a $300 lithium one that died from neglect.

5. Shorai LFX21L6-BS12 — Best Lightweight Performance Battery

The Shorai LFX21L6-BS12 was one of the first lithium batteries I tested in a Touring application, and it remains impressive years later. At just 3.36 pounds, it’s the lightest battery on this list while delivering 450 cranking amps.

Shorai’s lithium iron phosphate chemistry is inherently safer than other lithium types. I’ve never worried about thermal runaway or fire risk, even when charging in my garage. The battery includes active cell balancing, which extends lifespan by keeping all cells at optimal voltage.

The ultra-fast discharge rate means my starter spins viciously fast. This reduces wear on starter components and makes for effortless starts even after the bike has sat for weeks. I’m particularly impressed by how well it handles partial charges — it doesn’t develop memory effects like older battery types.

Installation and Compatibility

The Shorai requires a spacer kit to fit properly in the stock battery tray, which they include. I spent about 20 minutes on installation, mostly adjusting the case adapter. Make sure your best battery charger for harley davidson motorcycle has a lithium mode — standard chargers can damage these batteries.

At $250-290, it’s priced competitively with other lithium options. For riders who prioritize weight reduction and ultimate cranking performance, the Shorai delivers exceptional value in the lithium category.

6. Deka ETX20L — Best OEM Equivalent

When I want OEM-quality without paying dealer markups, I turn to Deka. The ETX20L is actually the manufacturer behind many private-label batteries, including some sold by Harley dealers. I’ve installed dozens of these in customer bikes over the years.

This AGM battery provides 270 cold cranking amps and 18 amp-hours capacity — identical specifications to the factory battery in 2012 Touring models. The absorbed glass mat separator technology prevents acid stratification and extends cycle life significantly.

What I respect about Deka is their manufacturing consistency. Every ETX20L I’ve tested performs identically, which tells me their quality control is tight. The batteries ship dry with the acid pack included, allowing for fresher activation and potentially longer shelf life.

Why Choose Deka?

At $100-130, the Deka costs less than Yuasa while offering comparable performance. I’ve gotten 4-5 years from these batteries with proper maintenance. They’re especially popular among riders who want reliable performance without premium pricing.

If you’re considering options similar to what might be the perfect battery for a harley davidson softtail motorcycle, the Deka’s versatility across multiple Harley models makes it worth considering for any Big Twin application.

7. FirePower Featherweight Lithium — Best Mid-Price Lithium

The FirePower Featherweight Lithium splits the difference between budget AGM and premium lithium batteries. At $200-240, it brings lithium technology within reach of more riders while maintaining the key benefits I value in lithium batteries.

This battery weighs just 4.8 pounds and delivers 425 cranking amps — more than adequate for the 2012 Touring’s starting requirements. The built-in LED charge indicator is surprisingly useful; I can check battery status at a glance without a voltmeter.

I’ve tested the FirePower through two full seasons, including winter storage. It holds charge exceptionally well, losing only about 5% over three months of sitting unused. The quick-recharge capability means I can top it off in under an hour before a ride.

Performance Balance

Where FirePower saves money is in the Battery Management System — it’s simpler than Antigravity’s sophisticated setup. You won’t get Re-Start functionality or quite as robust overcharge protection. For most riders, though, basic BMS features are sufficient.

The cranking power feels strong and consistent. My Twin Cam fires instantly even on cold mornings. While it doesn’t spin quite as aggressively as the Antigravity, the difference is minimal in real-world use.

For riders who want lithium benefits without the premium price tag, the FirePower represents the sweet spot. It’s light, powerful, and reliable enough for daily riding without demanding the investment of top-tier lithium batteries.

Choosing the Right Battery for Your Riding Style

After years of testing batteries in 2012 Touring models, I’ve learned that the “best” battery depends entirely on how you ride. Let me share how I match batteries to different riding profiles.

Daily Commuters and High-Mileage Riders

If you ride year-round and rack up serious miles, invest in premium AGM like the Yuasa YTX20L-BS or go lithium with the Antigravity. These batteries handle constant charge-discharge cycles better and maintain performance over thousands of miles. I’ve found they actually save money long-term through extended lifespan.

Regular riding keeps batteries healthy, so you’ll get maximum life from premium options. The superior cold cranking amps matter when you’re starting your bike every morning, regardless of weather.

Weekend Warriors and Seasonal Riders

For bikes that sit during the week or only come out seasonally, mid-tier AGM batteries like the Deka ETX20L make perfect sense. Pair any battery with a quality maintenance charger during storage periods. I keep my batteries on Battery Tender-style chargers whenever the bike sits more than a week.

Lithium batteries excel here too because they hold charge better during storage. The FirePower Featherweight offers lithium benefits at a price point that makes sense for occasional riders.

Performance and Custom Builds

If you’ve modified your 2012 Touring with performance upgrades or custom electronics, weight savings and cranking power become priorities. The Antigravity ATX20-RS or Shorai LFX21L6-BS12 are worth their premium prices in these applications.

I’ve seen lithium batteries paired beautifully with performance starters and high-output charging systems. The reduced weight improves handling noticeably, especially on baggers that already carry significant mass.

Battery Maintenance Tips I Wish I’d Known Sooner

Even the best battery fails prematurely without proper care. Here’s what I’ve learned through experience — some of it the hard way.

Winter Storage Protocol

I always remove batteries from bikes that sit unused for more than a month. Store them in a temperature-controlled space if possible; my basement maintains 50-60°F year-round, which is ideal. Connect a smart charger set to maintenance mode.

For lithium batteries, I store them at about 50-60% charge rather than fully charged. This extends cell life significantly. AGM batteries prefer storage at full charge with periodic top-offs.

Terminal Maintenance

I clean terminals twice yearly with a wire brush and apply dielectric grease to prevent corrosion. Loose connections cause more “bad battery” diagnoses than actual battery failures. I torque terminal bolts to 90-120 inch-pounds — tight enough to prevent loosening, but not so tight that I strip the lead posts.

Check voltage regularly with a multimeter. A healthy battery shows 12.6-12.8 volts at rest. Anything below 12.4 volts indicates the battery needs charging. Below 12.0 volts suggests potential problems.

Charging System Health

Your battery is only as good as the charging system feeding it. I verify charging voltage annually — it should read 13.5-14.5 volts at 2000 RPM with the engine warm. Low charging voltage kills batteries prematurely, while high voltage boils them dry.

The 2012 Touring’s voltage regulator occasionally fails, usually showing symptoms of overcharging first. Catching this early saves the battery and prevents more expensive electrical problems.

Final Thoughts on Battery Selection

After testing all these batteries in real-world conditions on my 2012 Touring models, I keep coming back to a simple truth: the best battery is the one that reliably starts your bike and fits your budget.

For most riders, the Yuasa YTX20L-BS offers the ideal balance of performance, longevity, and value. It’s the battery I recommend to friends without hesitation. If weight matters or you want cutting-edge technology, the Antigravity ATX20-RS justifies its premium price through superior performance and lifespan.

Budget-conscious riders shouldn’t feel pressured into expensive options. The ThrottleX HDX30L or Deka ETX20L deliver solid reliability at prices that won’t break the bank. Save the difference for riding gear or fuel.

Whatever battery you choose, remember that proper maintenance matters more than brand names. I’ve seen budget batteries outlast premium ones simply because the owner maintained them properly. Keep terminals clean, use a quality charger during storage, and verify your charging system health annually.

Your 2012 Touring is built to last decades with proper care. Choosing the right battery and maintaining it correctly ensures you’ll always be able to fire up that Twin Cam and hit the road when the riding bug bites.
