Everstart Battery Es9Bs

As a motorcycle enthusiast who’s gone through more batteries than I care to admit, I’ve learned a thing or two about what keeps our beloved bikes humming. After years of trial and error (and some embarrassing roadside moments), I’ve discovered that choosing the right battery can make all the difference between reliability and frustration. Today, I’m diving deep into the Everstart ES9BS battery – a popular option that might just be the unsung hero your motorcycle needs.

Let me take you through everything I’ve learned about this particular power cell, from its specs and performance to real-world applications. Whether you’re a seasoned rider or just starting your two-wheeled journey, this comprehensive guide will help you understand if the ES9BS is the right choice for your ride.

What Exactly Is the Everstart ES9BS Battery?

The Everstart ES9BS is a sealed lead-acid (SLA) battery specifically designed for motorcycles and similar small vehicles. When I first encountered this battery, I was immediately struck by its compact design and solid construction. As someone who’s handled dozens of motorcycle batteries over the years, I could tell this wasn’t just another cheap option.

This battery falls into the category of maintenance-free batteries, which is a huge plus for riders like me who prefer spending time on the road rather than fussing with battery maintenance. The ES9BS comes in a factory-sealed case that prevents leaks and eliminates the need for regularly checking and topping up electrolyte levels – something my older bikes always seemed to need at the most inconvenient times.

The ES9BS utilizes Absorbed Glass Mat (AGM) technology, which suspends the electrolyte in glass fiber separators between the lead plates. This design offers several advantages, including better vibration resistance (crucial for motorcycles) and improved electrical performance. In my experience, AGM batteries also tend to have a longer service life than traditional flooded batteries.

Is the Everstart ES9BS Actually Any Good?

After riding with an ES9BS for over two years and talking with countless other riders who use them, I can confidently say that this battery delivers excellent value for its price point. I’ve found it to be reliable, durable, and capable of handling the demands of regular motorcycle use.

What impresses me most about the ES9BS is its consistent starting power, even after sitting unused for a couple of weeks. I remember taking a break from riding during a particularly rainy month, only to find my bike starting right up when the sun finally came out – no trickle charger needed. That kind of reliability is worth its weight in gold for occasional riders.

That said, no battery is perfect. The ES9BS might not offer the same extreme performance as some premium batteries costing twice as much, but for most riders, the difference is negligible. I’ve pushed this battery through summer heat waves and chilly autumn mornings, and it’s rarely let me down.

Compatible Vehicles: Will It Fit Your Ride?

One of the most common questions I hear from fellow riders is whether the ES9BS will work with their particular motorcycle. Based on my research and experience, this battery is compatible with a wide range of motorcycles, including:

• Honda motorcycles (particularly CB, CBR, and Shadow series)
• Suzuki models (including GSXR, Bandit, and SV series)
• Kawasaki bikes (Ninja series, Vulcan, and many others)
• Yamaha motorcycles (R series, V-Star, and more)
• Various Triumph models
• Select Harley-Davidson Sportster models

Beyond motorcycles, the ES9BS is also suitable for:

• ATVs and UTVs (particularly smaller models)
• Jet skis and personal watercraft
• Snowmobiles
• Scooters and mopeds

The key to determining compatibility is checking your vehicle’s battery specifications against the ES9BS dimensions and electrical requirements. When I upgraded my Suzuki GSX-R600, I made sure to verify the battery compartment dimensions first – something I’d recommend to anyone considering this battery.

Technical Specifications: The Numbers That Matter

As a bit of a technical geek, I love diving into specifications. Here’s what you need to know about the ES9BS:

• Voltage: 12 volts (standard for most motorcycles)
• Capacity: Typically rated at 8 Ah (Ampere-hours)
• Cold Cranking Amps (CCA): Approximately 120 CCA
• Terminal Type: Typically comes with screw-type terminals
• Dimensions: Approximately 5.5″ × 3.4″ × 4.1″ (L × W × H)
• Weight: Around 6 pounds

When I first installed my ES9BS, I was pleasantly surprised by how compact it was compared to the original battery in my bike. The lighter weight is a nice bonus for performance-oriented riders who count every ounce.

The 120 CCA rating might seem modest compared to car batteries, but it’s more than adequate for most motorcycles. Even on colder mornings when batteries typically struggle, I’ve found the ES9BS delivers reliable starting power. That said, if you live in extremely cold climates (consistently below freezing), you might want to consider a battery with a higher CCA rating.

Battery Lifespan: How Long Will It Last?

In my experience, the average lifespan of an Everstart ES9BS battery ranges from 2-4 years with proper care. This is fairly standard for motorcycle batteries in this price range and depends heavily on usage patterns and maintenance.

I’m currently in my third year with my ES9BS, and while it’s showing some signs of age (slightly longer cranking times on cold mornings), it’s still performing reliably. A riding buddy of mine got nearly five years from his, though he’s meticulous about battery maintenance and always uses a trickle charger during off-seasons.

Factors that affect battery lifespan include:

1. Riding frequency (ironically, bikes that sit unused often have shorter battery lives)
2. Climate conditions (extreme heat accelerates battery deterioration)
3. Charging habits (proper charging extends life significantly)
4. Electrical system condition (a faulty charging system can quickly kill a battery)
5. Storage practices (cold, dry storage during off-seasons helps prolong life)

To maximize your battery’s lifespan, I recommend using a quality battery tender during periods of inactivity. The $30 I spent on a decent tender has paid for itself many times over in extended battery life.

Warranty Coverage: What’s Protected?

Everstart batteries typically come with a standard 1-year free replacement warranty. This is fairly standard in the industry, though not as generous as some premium brands that offer 2-3 year warranties.

In my experience with warranty claims (not specifically for the ES9BS, but for other Everstart products), the process is straightforward if you’ve kept your receipt. The key is having documentation of your purchase date and ensuring the battery failed due to a manufacturing defect rather than misuse.

When I had to replace a different Everstart battery under warranty, I simply brought it back to the retailer with my receipt, and they tested it on the spot. The process took about 15 minutes, and I walked out with a replacement battery at no cost. Your experience may vary depending on where you purchased the battery.

Where to Buy and What You’ll Pay

The Everstart ES9BS is widely available through various retailers. I’ve seen them most consistently at:

• Walmart (both in-store and online)
• Amazon and other online marketplaces
• Select auto parts stores

In terms of pricing, I’ve found the ES9BS typically retails between $45-$65, depending on promotions and retailer. This represents an excellent value proposition compared to OEM batteries that often cost $80-$120 for essentially the same specifications.

I purchased my current ES9BS during a sale for around $50, which I consider a bargain given its performance. When shopping, I recommend checking both online and local stores, as prices can vary significantly. Don’t forget to factor in any core charges (usually refundable when you return your old battery).

Maintenance-Free: What Does That Really Mean?

One of the biggest selling points of the ES9BS is its maintenance-free design. But what does that actually mean in practice?

Traditional flooded lead-acid batteries require periodic checking of electrolyte levels and occasionally adding distilled water. The ES9BS, being a sealed AGM battery, eliminates this requirement entirely. The battery is factory-sealed, meaning you never need to add water or check fluid levels.

This maintenance-free design has been a significant time-saver for me. With my previous flooded batteries, I was constantly checking levels, especially during hot summer months when evaporation was an issue. With the ES9BS, I simply install it and forget about it until it’s time for replacement.

That said, “maintenance-free” doesn’t mean “care-free.” You’ll still want to:

1. Keep the terminals clean and free of corrosion
2. Ensure proper charging between rides
3. Use a battery tender during storage periods

These simple steps have helped me extend the useful life of my battery significantly.

Cold Weather Performance: Will It Start When You Need It?

Living in an area with distinct seasons, I’ve put the ES9BS through its paces in varying temperatures. With approximately 120 CCA, this battery provides adequate starting power for most motorcycles in moderately cold conditions.

During my experiences with the ES9BS in winter months (temperatures around 30-40°F), the battery has performed admirably. Cold mornings might require a slightly longer cranking time, but I’ve rarely had issues getting my bike started.

However, I should note that if you regularly ride in extremely cold conditions (consistently below 20°F), you might want to consider a battery with a higher CCA rating. Alternatively, storing your motorcycle in a garage or using a battery tender overnight can help maintain starting power in colder temperatures.

One winter trick I’ve learned: if it’s particularly cold, turn on the ignition for about 30 seconds before attempting to start the bike. This allows the fuel pump to pressurize and electronics to warm up slightly, reducing the initial load on the battery during cranking.

Installation Guide: DIY in Under 15 Minutes

Installing the ES9BS is straightforward, even for beginners. Here’s my step-by-step process:

1. Gather your tools: You’ll need basic hand tools, typically just a Phillips screwdriver and potentially a small wrench set.
2. Locate your battery: On most motorcycles, the battery is under the seat or behind a side panel. Consult your owner’s manual if you’re having trouble finding it.
3. Disconnect the old battery: Always disconnect the negative (black) terminal first, then the positive (red). This prevents accidental shorts.
4. Remove any hold-down brackets or straps: These keep your battery secure during riding.
5. Remove the old battery: Lift it straight out, being careful not to tilt it excessively if it’s not sealed.
6. Clean the battery compartment: Use a mild solution of baking soda and water if there’s any corrosion.
7. Insert the new ES9BS battery: Make sure the terminals are oriented correctly to match your bike’s cables.
8. Connect the terminals: Connect positive (red) first, then negative (black). Tighten securely but don’t overtighten.
9. Secure the battery: Reinstall any hold-down brackets or straps.
10. Test: Turn on the ignition and check that your gauges and lights work before starting the engine.

My last installation took about 12 minutes from start to finish. The most time-consuming part was actually cleaning some minor corrosion from the battery cables – a step I never skip since it ensures good electrical contact.

Dimensions and Fit: Will It Fit Your Bike?

The physical dimensions of the ES9BS are approximately 5.5″ × 3.4″ × 4.1″ (L × W × H), and it weighs about 6 pounds. These measurements are important to verify against your motorcycle’s battery compartment.

When I installed mine in my Suzuki, the fit was perfect – almost identical to the OEM battery it replaced. However, I’ve heard from friends with custom bikes that sometimes minor adjustments are needed, such as adding foam padding to prevent movement or extending cables if the terminal positions don’t perfectly align.

If you’re unsure about compatibility, I recommend:

1. Removing your current battery and measuring the compartment
2. Checking your motorcycle’s manual for battery specifications
3. Consulting battery cross-reference charts (available at most auto parts stores)

Remember that in some cases, a slightly smaller battery might work with appropriate securing methods, but a larger battery simply won’t fit in your compartment.

Beyond Motorcycles: ATVs, Scooters, and More

While primarily marketed for motorcycles, the ES9BS is versatile enough for several other applications. I’ve personally used this battery model in:

• My brother’s Yamaha Grizzly ATV (worked perfectly)
• A friend’s 150cc scooter (significant upgrade from the original battery)
• My neighbor’s jet ski (as a temporary replacement that ended up lasting two seasons)

The key to successful crossover use is matching the voltage (12V), ensuring the physical dimensions are compatible, and verifying that the capacity (Ah) and CCA ratings meet your vehicle’s needs.

For smaller scooters and ATVs, the ES9BS often provides more power than necessary, which translates to improved reliability and longevity. However, for larger ATVs or watercraft with more powerful engines, you might need a battery with higher capacity and CCA ratings.

Comparative Analysis: How Does It Stack Up?

Having tried numerous batteries over the years, I can offer some perspective on how the ES9BS compares to alternatives:

ES9BS vs. OEM Batteries
The ES9BS typically offers comparable performance to most OEM batteries at a significantly lower price point. In my experience, the only notable difference is that some premium OEM batteries might have slightly higher CCA ratings or longer warranties.

ES9BS vs. Premium Aftermarket Batteries (Yuasa, Motobatt, etc.)
Premium batteries often offer higher CCA ratings, longer warranties (2-3 years vs. 1 year), and potentially longer lifespans. However, they usually cost 50-100% more than the ES9BS. For casual riders, the performance difference rarely justifies the cost difference.

ES9BS vs. Lithium Batteries
Lithium batteries are significantly lighter (typically 2-3 pounds vs. 6 pounds) and offer better cold-weather performance, but cost 3-4 times more than the ES9BS. They’re a great upgrade for performance bikes but overkill for most riders.

For my money, the ES9BS hits the sweet spot of performance and value. Unless you’re racing or riding in extreme conditions, the premium options offer diminishing returns on your investment.

Charging Procedures: Doing It Right

Proper charging is crucial to maximizing your ES9BS battery’s life. Here’s my recommended approach:

For routine maintenance charging:

1. Use a quality motorcycle battery charger or tender rated for 12V batteries
2. Most modern chargers are automatic and will sense the battery’s charge level
3. Connect the positive (red) lead first, then the negative (black)
4. A full charge typically takes 4-8 hours if the battery is low

For initial charging (if the battery comes partially charged):

1. Check the voltage with a multimeter if possible (should read at least 12.4V for a healthy charge)
2. If below 12.4V, charge with a motorcycle-specific charger before installation
3. Avoid using automotive fast-chargers, which can damage motorcycle batteries

I’ve found that regularly using a quality battery tender is the single best investment you can make to extend battery life. Mine stays connected whenever the bike sits for more than a week, and I’m convinced this practice has added at least a year to my battery’s useful life.

Environmental Considerations: Disposal and Recycling

Lead-acid batteries, including the ES9BS, contain materials that can be harmful to the environment if not properly disposed of. Here’s what I do when it’s time to replace my battery:

1. Never throw batteries in regular trash: This is illegal in most places and environmentally harmful.
2. Take advantage of recycling programs: Most retailers that sell batteries will accept your old ones for recycling. When I bought my replacement battery, I simply brought the old one to the same store.
3. Look for core charge refunds: Many places charge a “core charge” (typically $5-10) when you buy a new battery, which is refunded when you return your old one.

The good news is that lead-acid batteries are among the most recycled products in the world, with recovery rates often exceeding 95%. Almost every component of your old ES9BS can be reclaimed and used in new products.

Does It Come Pre-Charged? What to Expect Out of the Box

In my experience, the ES9BS typically comes partially charged from the factory. When I purchased mine, it had enough charge to start my bike immediately, but this isn’t always guaranteed.

For best results, I recommend:

1. Checking the voltage with a multimeter if you have one (ideally 12.4V or higher)
2. Giving the battery a full charge before installation if possible
3. At minimum, ensuring the battery has been stored properly before purchase

Most ES9BS batteries will have a manufacturing date code stamped somewhere on the case. Batteries less than six months old typically retain most of their factory charge, while older inventory might need charging before use.

One thing to note: if you purchase your battery online, temperature extremes during shipping can affect the charge level. When my friend ordered his ES9BS during a summer heat wave, it arrived needing a full charge before it would start his bike.

Maintenance Tips from a Fellow Rider

Based on my years of experience with motorcycle batteries, here are my top maintenance tips for the ES9BS:

1. Use it regularly: Batteries discharge naturally when sitting unused. A weekly ride of at least 20 minutes helps maintain charge.
2. Keep it clean: Periodically check terminals for corrosion and clean with a wire brush if necessary.
3. Secure it properly: Ensure the battery is firmly mounted to minimize vibration, which can damage internal components.
4. Address electrical issues promptly: If you notice dimming lights or difficulty starting, diagnose and fix electrical problems before they damage your battery.
5. Disconnect during long storage: If storing your bike for months, either disconnect the battery or use a tender. Modern bikes have small parasitic draws that can drain batteries over time.
6. Avoid deep discharges: Try not to let your battery discharge below 12.0V, as this can significantly reduce its lifespan.

My most valuable tip: invest in a quality battery tender and use it religiously when your bike isn’t being ridden regularly. The $30-50 investment can double your battery’s useful life.

Real Rider Reviews: What Others Are Saying

While my personal experience with the ES9BS has been largely positive, I wanted to include perspectives from other riders I’ve spoken with:

Sarah, who rides a Honda CBR600: “I was skeptical about going with a non-OEM battery, but the ES9BS has been solid for two seasons now. Starts every time, even after sitting for a couple of weeks.”

Mike, Harley Sportster owner: “It’s a decent battery for the price. Not quite as powerful as the Harley-branded battery, but at half the price, I can live with that. Cold mornings take an extra crank or two.”

Raj, who uses it in his Kawasaki Ninja: “Perfect fit, perfect performance. Three years in and still going strong. Best value battery I’ve found.”

Jason, weekend rider: “Mine failed after 14 months, just outside the warranty period. That was disappointing, but even buying a replacement meant I spent less than one OEM battery would have cost.”

The general consensus seems to align with my experience: the ES9BS offers excellent value for casual to moderate riders, though serious enthusiasts who ride in extreme conditions might benefit from investing in premium options.
