Everstart Tx20L

I still remember the day my motorcycle refused to start in the middle of nowhere, leaving me stranded on a backcountry road with no cell service. That frustrating experience taught me a valuable lesson about motorcycle batteries that I’ll never forget. After researching extensively and testing various options over the years, I’ve become somewhat of an Everstart TX20L battery enthusiast. Today, I’m sharing everything I’ve learned to help fellow riders avoid the pitfalls I’ve experienced and get the most out of this powerful little battery.

Whether you’re a weekend warrior, daily commuter, or adventure tourer, your motorcycle’s battery is the heartbeat of your riding experience. Let me walk you through everything you need to know about the Everstart TX20L – from selection to installation, maintenance to replacement – all based on my real-world experience and technical knowledge gained over years of riding.

What Exactly Is the Everstart TX20L Battery?

Before diving into the details, let’s clarify what we’re talking about. The Everstart TX20L is a 12-volt powersports battery primarily designed for motorcycles, but versatile enough for various small engine applications. It’s classified as a YTX20L-BS equivalent, which is a standard size and specification in the powersports world.

When I first purchased my Harley-Davidson Sportster, I was overwhelmed by the battery options available. The dealer wanted to sell me an expensive OEM battery, but my research led me to the Everstart TX20L as a cost-effective alternative that didn’t compromise on performance.

The Everstart TX20L is a sealed, maintenance-free AGM (Absorbed Glass Mat) battery that delivers reliable starting power for motorcycles, ATVs, and other powersports vehicles at a fraction of the cost of many premium brands. This was the key selling point for me – professional-grade performance without the professional-grade price tag.

Applications: What Vehicles Work With the Everstart TX20L?

One of the most common questions I get from fellow riders is whether the TX20L will fit their particular motorcycle. Based on my experience and research, this battery is compatible with a wide range of motorcycles, particularly:

• Harley-Davidson models (including many Sportsters, Softails, Dynas, and touring models)
• Honda cruisers and touring bikes (particularly the larger displacement models)
• Yamaha V-Stars, Road Stars, and other cruisers
• Suzuki Boulevard series and larger sportbikes
• Kawasaki Vulcan series and other cruisers
• Many Victory and Indian motorcycle models
• Larger displacement BMW motorcycles

Beyond motorcycles, the TX20L works great in:

• Many ATVs (particularly 500cc and larger)
• Personal watercraft (jet skis)
• Snowmobiles
• Small utility vehicles

I’ve personally used the TX20L in both my Harley Sportster and later in my Honda Shadow with perfect fitment and performance. The key is to check your vehicle’s battery compartment dimensions and terminal configuration.

When I was considering this battery for my buddy’s Kawasaki Vulcan, we measured his existing battery and compared it to the TX20L’s dimensions (more on those later) to ensure it would fit properly. This simple step saved us from potential headaches during installation.

Technical Specifications: Understanding What You’re Getting

When I first started researching motorcycle batteries, the technical specifications seemed like a foreign language. Now I understand how crucial these numbers are to finding the right power source for your specific needs.

Dimensions and Weight

The Everstart TX20L measures approximately:

• Length: 6.88 inches (175 mm)
• Width: 3.44 inches (87 mm)
• Height: 6.12 inches (155 mm)
• Weight: About 14-15 pounds (6.3-6.8 kg)

I learned the importance of these measurements the hard way when I tried to fit a different battery into my first motorcycle without checking dimensions. The height was off by just half an inch, but it made installation impossible. Don’t make my mistake – always verify dimensions before purchasing!

Capacity and Power Ratings

The TX20L typically offers:

• Voltage: 12 volts
• Ampere-Hour Capacity: 18-20 Ah (amp-hours)
• Cold Cranking Amps (CCA): Approximately 270-310 CCA
• Reserve Capacity: Around 30-35 minutes

The amp-hour rating indicates how much energy the battery can store, while CCA measures its ability to start your engine in cold conditions. When I moved from Florida to Colorado, I quickly learned how important those CCA numbers were for cold morning starts in the mountains.

Battery Technology

The TX20L uses Absorbed Glass Mat (AGM) technology, which means:

• The electrolyte is absorbed in special glass mat separators
• The battery is completely sealed and maintenance-free
• It’s spill-proof and can be mounted in various positions
• It has lower self-discharge rates than conventional batteries

This technology has been a game-changer for me. My previous conventional battery required regular checking and topping off with distilled water – a maintenance task I often forgot. With the TX20L’s maintenance-free design, I simply install it and forget about it until replacement time.

Longevity: How Long Can You Expect Your TX20L to Last?

Battery life is a major concern for any rider, and I’ve tracked my experiences closely. With proper care, my Everstart TX20L batteries have typically lasted between 3-5 years of regular use. Several factors affect this lifespan:

Riding Frequency

I’ve noticed that motorcycles ridden regularly tend to have better battery life than those that sit for extended periods. When I was commuting daily on my Sportster, the battery lasted nearly 5 years. My weekend-only Honda saw its battery life reduced to about 3 years due to the longer periods of inactivity.

Charging System Health

A motorcycle’s charging system plays a crucial role in battery longevity. When my Harley developed a stator issue that caused undercharging, my battery’s lifespan was cut short dramatically. After repairing the charging system, my next TX20L lasted significantly longer.

Climate Conditions

Extreme temperatures affect all batteries, and the TX20L is no exception. During my time riding in Florida, high heat accelerated battery aging. Conversely, extremely cold conditions reduce performance temporarily but don’t necessarily shorten overall lifespan if the battery is properly maintained.

Electrical Accessories

Adding power-hungry accessories like heated grips, auxiliary lights, or sound systems increases the load on your battery. When I added LED auxiliary lights to my touring bike, I noticed the increased drain and made sure to ride longer distances regularly to ensure full charging.

The Value Proposition: Cost Considerations

One of the most appealing aspects of the Everstart TX20L is its affordability. Typically priced between $60-$90 (as of my last purchase), it offers significant savings compared to OEM batteries that often run $120-$200 for equivalent specifications.

This price point doesn’t reflect a compromise in quality but rather the advantage of Walmart’s massive purchasing power and distribution network. I’ve found the performance nearly identical to batteries costing twice as much.

When my riding buddy needed a new battery for his Harley Road King, he was shocked at the $180 price tag from the dealership. I recommended the TX20L, which he purchased for around $75. Three years later, he’s still riding with that same battery with zero issues.

Where to Purchase Your Everstart TX20L

As an Everstart product, the TX20L is primarily available at Walmart stores nationwide. I’ve purchased these batteries both in-store and through Walmart’s online platform. My experiences with both have been positive, but I prefer in-store purchase for a few reasons:

1. You can check the manufacturing date directly (fresher is better)
2. You can avoid shipping delays and potential shipping damage
3. Returns or warranty claims are typically easier with in-store purchases
4. Some stores have battery testing equipment to verify your old battery’s condition

When purchasing in-store, I always ask an associate to check the stock room for the newest batch if the ones on display seem to have been sitting around for a while. A freshly manufactured battery will provide longer service life than one that’s been sitting on a shelf for months.

Installation Guide: Getting Your TX20L Up and Running

Installing a motorcycle battery might seem intimidating if you’ve never done it before, but it’s actually one of the simpler maintenance tasks you can perform. Here’s my step-by-step process that has served me well over multiple battery changes:

Preparation

1. Gather your tools: typically just basic wrenches or socket set, maybe a Phillips screwdriver
2. Ensure your motorcycle is turned off and the key is removed
3. Locate your battery (usually under the seat or behind a side panel)

Removal of Old Battery

1. Always disconnect the negative (black) terminal first, then the positive (red)
2. Remove any battery hold-down straps or brackets
3. Carefully lift out the old battery, noting its orientation

Installation of New TX20L

1. Before installation, I always verify that the new battery’s terminals match the orientation of the old one
2. Place the new TX20L in the battery box in the same orientation as the old battery
3. Reconnect the positive (red) terminal first, then the negative (black) – this sequence is important for safety
4. Secure any hold-down mechanisms to prevent battery movement
5. Double-check that all connections are tight but not over-tightened

The first time I changed my motorcycle’s battery, I was nervous about getting something wrong. Now it’s a 15-minute job that I can do without even consulting instructions. The most common mistake I see riders make is reversing the connection order – always disconnect negative first and reconnect it last!

Charging Your TX20L: Maximizing Performance and Lifespan

Proper charging is perhaps the single most important factor in maximizing your TX20L’s lifespan. Through trial and error (and one prematurely dead battery), I’ve developed a reliable charging routine:

Initial Charging

Although the TX20L often comes partially charged, I always give it a full charge before installation. This ensures maximum performance from day one and helps establish a good baseline for the battery’s condition.

I use a quality motorcycle-specific smart charger with an AGM setting. These typically cost $40-$60 but are worth every penny for extending battery life. My Battery Tender Junior has paid for itself many times over in extended battery life.

Maintenance Charging

For motorcycles that sit for extended periods (more than two weeks), I use a maintenance charger. Modern smart chargers can be left connected indefinitely without overcharging, keeping the battery at optimal voltage.

When I stored my Harley for three months during a particularly harsh winter, keeping it on a maintenance charger ensured it started immediately when riding season returned. My neighbor, who skipped this step, needed a new battery come springtime.

Charging After Deep Discharge

If your TX20L becomes deeply discharged (happens to the best of us!), it’s crucial to recharge it promptly. AGM batteries can be damaged if left in a discharged state for extended periods.

I once accidentally left my headlight on overnight, completely draining my battery. By using a slow, gentle charge rate (about 2 amps) on my smart charger, I was able to recover the battery without permanent damage.

Warranty Coverage: Your Safety Net

One aspect of the Everstart TX20L that gives me confidence is its warranty coverage. Typically, these batteries come with a warranty period ranging from 12 to 24 months, depending on the specific model and when you purchased it.

I’ve only had to use the warranty once, when a battery developed a cell issue about 8 months after purchase. The process at Walmart was straightforward:

1. I brought in the defective battery along with my receipt
2. They tested the battery to verify the failure
3. I received a replacement on the spot

To maintain warranty coverage, keep your receipt in a safe place and follow proper maintenance procedures. Most warranties won’t cover damage from improper charging, extreme deep cycling, or physical damage.

Real-World Performance: How the TX20L Handles Different Conditions

Through years of riding in various conditions, I’ve put the TX20L through its paces. Here’s how it performs in different scenarios:

Cold Weather Performance

Living in Colorado has given me plenty of opportunities to test cold-weather starting. While all lead-acid batteries (including AGM) lose some capacity in cold temperatures, the TX20L has consistently started my motorcycle down to about 20°F (-7°C) without issues.

For extremely cold conditions (below 15°F/-9°C), I’ve found that either briefly turning on the headlight for 30 seconds before attempting to start (to “wake up” the battery) or using a battery tender overnight significantly improves starting performance.

Hot Weather Performance

During summer rides through the Southwest, with temperatures exceeding 100°F (38°C), I’ve observed that the TX20L holds up well but requires more vigilant maintenance. Extreme heat accelerates the chemical reactions inside batteries, potentially shortening their lifespan.

I’ve found that parking in shaded areas when possible and maintaining proper charging has helped mitigate heat-related degradation. My TX20L lasted over four years despite regular exposure to Arizona summer temperatures.

Off-Road and Vibration Resistance

One advantage of AGM technology is superior vibration resistance compared to flooded batteries. When I used the TX20L in my dual-sport motorcycle for off-road adventures, it held up remarkably well despite the constant jolting and vibration.

The secure internal construction prevented the plate damage that can occur in conventional batteries under similar conditions. This makes the TX20L particularly well-suited for ATVs and off-road motorcycles.

Comparing the Everstart TX20L to Competitors

I’ve had the opportunity to use several different battery brands over my riding career. Here’s how the TX20L stacks up against common alternatives:

Yuasa (OEM for many motorcycles)

Yuasa batteries are excellent and often come as original equipment on many motorcycles. However, they typically cost 50-100% more than the TX20L while offering very similar performance. In my experience, the real-world performance difference doesn’t justify the price premium for most riders.

Battery Tender (Premium Aftermarket)

Battery Tender’s lithium batteries offer significant weight savings (often 70-80% lighter) and better cold-weather performance, but at 3-4 times the price of the TX20L. For racing or premium applications where weight matters significantly, they make sense. For everyday riding, the TX20L’s value is hard to beat.

Chrome Battery and Mighty Max (Budget Alternatives)

These budget-oriented alternatives sometimes undercut the TX20L on price by $10-20, but in my testing, they didn’t match its reliability or longevity. I tried a Chrome Battery in my ATV that lasted only 18 months compared to the nearly three years I got from the TX20L.

DIY Evaluation Method

When deciding between battery options, I use a simple formula: divide the battery price by expected months of service to get a “cost per month” figure. By this metric, the TX20L consistently outperforms both cheaper and more expensive alternatives in my experience.

The TX20L for ATVs and Other Powersports Applications

While primarily marketed for motorcycles, I’ve successfully used the TX20L in several other applications with excellent results:

ATV Performance

When I needed a replacement battery for my Polaris Sportsman ATV, the TX20L proved to be an excellent fit. The higher capacity compared to the original equipment battery actually improved starting performance, particularly on cold mornings.

The sealed design was particularly valuable for ATV use, as the battery is often subjected to splashing water, mud, and extreme angles during off-road adventures. After a particularly muddy ride that submerged my ATV briefly, the battery continued to perform flawlessly thanks to its sealed construction.

Personal Watercraft Applications

A riding friend used the TX20L in his Kawasaki Jet Ski with excellent results. The vibration resistance and sealed design made it ideal for marine use, where conventional batteries often fail prematurely due to moisture intrusion and constant pounding through waves.

Specialty Vehicles

I’ve even seen the TX20L successfully employed in small utility vehicles and golf carts (though multiple batteries are required for golf carts). The versatility of this battery makes it suitable for nearly any 12V powersports application within its capacity range.

Maintenance Tips: Keeping Your TX20L in Peak Condition

While marketed as “maintenance-free,” all batteries benefit from proper care. Here are my time-tested maintenance practices that have helped me maximize the lifespan of my TX20L batteries:

Regular Visual Inspection

I make it a habit to visually inspect my battery approximately once a month, looking for:

• Any signs of corrosion on terminals
• Cracks or bulging in the case
• Secure mounting (loose batteries can be damaged by vibration)

This quick 30-second check has helped me catch potential issues before they become problems.

Terminal Maintenance

Battery terminals are prone to corrosion, which can impede current flow. I clean my terminals with a wire brush and apply a thin coat of dielectric grease or terminal protectant every 6 months. This simple step ensures reliable connections and prevents the frustrating “no-start” situations that often occur due to poor connections rather than actual battery failure.

Riding Habits

I’ve found that regular riding actually benefits battery health. Motorcycles that sit unused for weeks tend to develop battery issues faster than those ridden frequently. I try to ensure my motorcycle gets at least 30 minutes of runtime weekly, which is sufficient for the charging system to replenish the battery.

For longer storage periods, I either remove the battery and keep it on a maintenance charger or leave a smart charger connected to the motorcycle.

Avoiding Deep Discharge

AGM batteries like the TX20L can be damaged by repeated deep discharges. I’m careful to avoid running accessories like heated gear or lights when the engine is off for extended periods. The one time I accidentally left my headlight on overnight resulted in a significantly weakened battery that never quite recovered its full capacity.

Recycling Your Old TX20L: Environmental Responsibility

When it’s finally time to replace your TX20L, proper disposal is essential. Lead-acid batteries (including AGM types) contain materials that are harmful to the environment but valuable for recycling.

I take my old batteries back to Walmart (where I purchased my replacement) for recycling. Most auto parts stores also accept old batteries for recycling, often offering a small core charge refund. Some locations even pay a few dollars for old batteries due to the value of the lead content.

Never dispose of batteries in regular trash or leave them exposed to the elements, as the lead and acid can cause environmental damage. Responsible recycling ensures the materials are properly handled and many components reused.

Signs Your TX20L Needs Replacement

Through years of riding, I’ve learned to recognize the warning signs that indicate a battery is nearing the end of its useful life:

Starting Performance Degradation

The most obvious sign is progressively weaker starting performance. When my Harley began requiring longer cranking times to start, especially on cooler mornings, it was the first indicator that the battery was aging.

Inability to Hold Charge

If your fully charged TX20L drains significantly after just a few days of sitting unused, it’s likely developing internal resistance issues common in aging batteries. My rule of thumb: if it loses enough charge to affect starting performance within a week of inactivity, it’s time to start shopping for a replacement.

Physical Changes

Visual clues can also indicate battery failure:

• Bulging or warped case (indicating internal damage)
• Excessive terminal corrosion that returns quickly after cleaning
• Leakage of any kind (though rare with AGM batteries)

Age-Based Replacement

Even without obvious symptoms, I consider replacing my TX20L proactively after 4 years of service. This preventive approach has helped me avoid being stranded with a failed battery, which typically costs more in inconvenience than the price of a planned replacement.

Alternative Options: When the TX20L Might Not Be Right for You

While I’ve had great experiences with the TX20L, it’s not the perfect solution for every rider or vehicle. Here are some scenarios where you might consider alternatives:

Lithium Replacement Options

For riders prioritizing weight savings, lithium iron phosphate (LiFePO4) batteries offer dramatic weight reduction (often 70-80% lighter than the TX20L) and longer life, albeit at a significantly higher price point (typically $150-300). I have riding friends who swear by these for racing applications where every pound matters.

Higher Capacity Needs

If you’ve added numerous electrical accessories to your motorcycle or have a particularly large engine with high starting current requirements, you might need a battery with higher capacity than the TX20L offers. Some touring motorcycles with extensive electrical systems benefit from Group 65 or larger batteries.

Extreme Cold Weather Applications

For riders in extremely cold climates (regular riding in sub-zero temperatures), either a higher CCA conventional battery or a lithium battery with a heating element might provide better cold-weather starting reliability than the TX20L.

Final Thoughts: Why the TX20L Remains My Go-To Choice

After years of experimenting with various batteries across multiple motorcycles and powersports vehicles, the Everstart TX20L continues to earn its place as my recommended battery for most riders. Its combination of reliability, performance, and value is difficult to match.

The TX20L strikes the perfect balance between affordability and performance, delivering reliable power across a wide range of conditions without the premium price tag of dealer alternatives.

For the average rider who wants dependable starting power without breaking the bank, this battery consistently delivers. The peace of mind I’ve experienced knowing my motorcycle will start reliably, regardless of whether it’s been sitting for a week or ridden daily, is worth far more than the modest investment the TX20L requires.

Whether you’re restoring a classic motorcycle, maintaining your daily rider, or outfitting an ATV for weekend adventures, the Everstart TX20L deserves serious consideration as your power source of choice. Just remember that, like any battery, its longevity and performance are directly tied to proper installation, charging, and maintenance.

Here’s to many trouble-free starts and countless miles of adventure powered by this unassuming but capable little battery!
