Why Getting the Right Polaris Outlaw 110 Battery Size is Non-Negotiable

It might seem like any small powersports battery will do the trick, but that’s a common mistake that leads to more problems down the road. The size and specs of your ATV’s battery are engineered specifically for the machine. Getting it wrong isn’t just an inconvenience; it can cause real issues.

The benefits of polaris outlaw 110 battery size being correct are simple: reliability and safety. An incorrect battery can lead to a host of common problems with polaris outlaw 110 battery size, and you want to avoid them at all costs.

The Triple Threat: Dimensions, Terminals, and Power

When we talk about “size,” we’re looking at three critical factors:

Physical Dimensions (L x W x H): The battery compartment on the Outlaw 110 is a snug fit. A battery that’s too big simply won’t go in. One that’s too small will vibrate excessively, leading to internal damage and a drastically shorter lifespan.
Terminal Orientation: The positive (+) and negative (-) terminals must be in the correct position. If they’re reversed, your battery cables won’t reach, and forcing them can cause damage to the cables or terminals.
Electrical Specifications: This includes Cold Cranking Amps (CCA) and Amp Hours (Ah). A battery with too little CCA will struggle to turn the engine over, especially in cooler weather. It needs the right power reserve to keep the EFI system and lights running properly.

Identifying Your Exact Polaris Outlaw 110 Battery Size

Alright, let’s get down to the brass tacks. This is the core of our polaris outlaw 110 battery size guide. The good news is that Polaris has kept things pretty consistent for the Outlaw 110, making your job much easier. Here’s how you find the exact battery you need.

The OEM Standard: What Battery Does a Polaris Outlaw 110 Use?

The most common factory-spec battery for the Polaris Outlaw 110 EFI is a YTX5L-BS. This is a standard powersports battery part number you’ll see across many brands.

Let’s decode that part number:

YTX: This designates it as a high-performance, sealed AGM maintenance-free battery made by Yuasa or to their standard.
5L: This refers to the power output and physical size group.
-BS: This means the battery is shipped “Bottle Supplied,” where you (or the retailer) add the acid pack and seal it before the first use. Most today come factory-activated.

The typical dimensions for a YTX5L-BS battery are approximately: 4.43″ (L) x 2.75″ (W) x 4.12″ (H). Always double-check the specs of the replacement you’re buying, but this is the size that fits perfectly in the Outlaw’s battery tray.

How to Confirm Your Current Battery Size (The Foolproof Method)

While the YTX5L-BS is the standard, the absolute best practice is to look at the battery currently in your ATV. A previous owner may have installed a slightly different but compatible model. This is one of the most important how to polaris outlaw 110 battery size tips we can offer.

Simply locate the battery under the seat, read the label on the top or side, and jot down the part number. This removes all guesswork.

Choosing Your Replacement Battery: AGM vs. Lithium

You’ve confirmed the size, and now you have a choice to make. For the Outlaw 110, you’ll primarily be deciding between two modern battery technologies: AGM and Lithium. Each has its pros and cons.

The Workhorse: AGM (Absorbed Glass Mat) Batteries

AGM batteries are the most common and recommended choice for the Outlaw 110. They are a type of sealed lead-acid battery that is completely maintenance-free. The electrolyte is absorbed in fiberglass mats, making them spill-proof and highly resistant to vibration—perfect for an off-road machine.

Pros:

Reliable and Proven: This technology is trusted and has been the standard for years.
Cost-Effective: AGM batteries offer the best balance of performance and price.
Vibration Resistant: Built to handle the bumps and jumps of the trail.
No Maintenance: Once sealed, you never have to check water levels.

Cons:

Heavier: They are significantly heavier than their lithium counterparts.

The Upgrade: Lithium (LiFePO4) Batteries

Lithium Iron Phosphate (LiFePO4) batteries are the premium option. If you’re looking for lighter weight and a longer service life, this is the way to go. They can be a fantastic performance upgrade, especially for a small, lightweight ATV.

Pros:

Extremely Lightweight: Can shave several pounds off the ATV, a noticeable difference on a small machine.
Longer Lifespan: Can last 2-4 times longer than an AGM battery with proper care.
Faster Charging: They can be recharged much more quickly.
Consistent Power: They deliver strong cranking power until they are nearly depleted.

Cons:

Higher Initial Cost: Lithium batteries are considerably more expensive upfront.
Charger Specific: You must use a lithium-compatible charger or battery tender to avoid damaging the battery.

Step-by-Step Guide: How to Replace Your Polaris Outlaw 110 Battery

Ready to get your hands dirty? This process is straightforward and should only take you about 15-20 minutes. Following these polaris outlaw 110 battery size best practices for installation will ensure a safe and successful job.

Tools & Safety Gear You’ll Need

Gather your gear first. You won’t need much.

Safety Glasses & Gloves
Socket Wrench or Nut Driver (usually 8mm or 10mm)
Wire Brush or Terminal Cleaner
Dielectric Grease (highly recommended)

Removing the Old Battery (The Safe Way)

Safety first, always. Working with batteries is generally safe, but you need to prevent accidental shorts.

Access the Battery: Lift and remove the seat on the Outlaw 110. The battery will be right there in its tray, secured by a rubber strap.
Disconnect the Negative Terminal FIRST: Use your wrench to loosen the bolt on the negative (-) black terminal. Wiggle the cable off and tuck it away from the battery post. This is the most critical safety step. Disconnecting the negative first prevents any accidental sparks if your tool touches the frame while loosening the positive terminal.
Disconnect the Positive Terminal: Now, loosen the bolt on the positive (+) red terminal. Remove the cable.
Remove the Hold-Down: Unhook the rubber strap holding the battery in place.
Lift the Battery Out: Carefully lift the old battery straight out of the tray.

Installing the New Battery

Putting the new battery in is just the reverse of removal, with a couple of key differences.

Clean Everything: Before you drop the new battery in, take a moment to clean the battery tray of any dirt or debris. Use a wire brush to clean the inside of the cable terminals until they are shiny. A clean connection is a good connection.
Place the New Battery: Set your new, fully charged battery into the tray, ensuring it sits flat and secure.
Secure the Hold-Down: Re-attach the rubber strap over the top of the battery to hold it firmly in place.
Connect the Positive Terminal FIRST: Attach the positive (+) red cable to the corresponding terminal on the new battery. Tighten the bolt until it’s snug. Don’t overtighten.
Connect the Negative Terminal LAST: Now, connect the negative (-) black cable to its terminal and tighten it. Connecting the ground last is the safest procedure.
Apply Dielectric Grease: This is a pro tip. Smear a light coating of dielectric grease over the terminals and connections. This prevents corrosion and ensures a solid electrical connection for years to come.
Test Your Work: Put the key in the ignition, turn it on, and hit the start button. The Outlaw should fire right up! Reinstall the seat, and you’re ready to ride.

Polaris Outlaw 110 Battery Size Care Guide: Pro Tips for a Longer Life

A new battery is a significant investment. With a proper polaris outlaw 110 battery size care guide, you can easily double its lifespan. ATVs are often stored for weeks or months at a time, which is the number one killer of powersports batteries.

The Power of a Battery Tender

If you take away only one tip from this section, let it be this: use a battery tender. A “tender” or “maintainer” is a smart charger that monitors your battery and applies a slow, small charge only when needed. It keeps the battery at its optimal voltage without overcharging it.

This single tool prevents sulfation (the buildup of lead sulfate crystals) and is the best way to ensure your ATV starts every single time, even after sitting all winter.

Keep it Clean, Keep it Charged

Periodically check your battery terminals. Even with dielectric grease, mud and moisture can find their way in. Keep the top of the battery and the terminals clean and dry.

If you don’t use a tender, make a point to start and run the ATV for 15-20 minutes every couple of weeks to allow the machine’s charging system to top off the battery.

Sustainable and Eco-Friendly Battery Disposal

Part of responsible ownership is proper disposal. Lead-acid batteries are highly recyclable but also hazardous waste. Never throw an old battery in the trash.

The best approach for a sustainable polaris outlaw 110 battery size solution is to simply take your old battery with you when you buy the new one. Nearly all auto parts stores and battery retailers will take your old battery for recycling, and many will even give you a small credit (a “core charge” refund) for it.

Frequently Asked Questions About Polaris Outlaw 110 Battery Size

What is the standard battery for a Polaris Outlaw 110?

The most common and direct replacement battery for the Polaris Outlaw 110 is the YTX5L-BS. This is a sealed AGM battery with dimensions of approximately 4.43″ x 2.75″ x 4.12″.

Can I use a bigger battery in my Outlaw 110?

No, it is not recommended. The battery tray is designed for the specific dimensions of the YTX5L-BS battery. A larger battery will not fit, and a smaller one will vibrate and fail prematurely. Stick with the correct size for proper fitment and performance.

How often should I replace the battery on my Outlaw 110?

With proper care and the regular use of a battery tender, a quality AGM battery can last 3 to 5 years. If the ATV is stored for long periods without a tender or is frequently deep-discharged, you may only get 1 to 2 seasons out of it.

Do I need a special charger for an ATV battery?

Yes, you should use a powersports-specific charger or a smart charger with a low-amperage setting (typically 1-2 amps). Using a high-amperage car charger can overheat and permanently damage a small ATV battery. If you upgrade to a lithium battery, you must use a lithium-compatible charger.

Getting the polaris outlaw 110 battery size right is the first step to a reliable, fun-filled ride. By choosing the correct YTX5L-BS battery, installing it safely, and maintaining it with a battery tender, you’re setting yourself up for seasons of trouble-free starting.

Now you have the expert knowledge to tackle this job with confidence. No more canceled rides or frustrating clicks—just the roar of an engine ready for the trail. Get out there, stay safe, and have a blast!
