What is the Correct 2008 Can-Am DS 450 Battery Size?
Let’s get straight to the point. The factory-specified battery for the 2008 Can-Am DS 450 is a YTX7L-BS. This alphanumeric code is a standardized industry part number that tells you everything you need to know about the battery’s size, terminal placement, and power output.
Getting this right is non-negotiable. An incorrectly sized battery can lead to fitment issues, poor connections, or insufficient power to start your high-compression engine, especially on a cold morning. This section of our 2008 Can Am DS 450 battery size guide will break down what that code really means.
Understanding Battery Naming Conventions
That “YTX7L-BS” isn’t just a random string of characters. Each part has a meaning:
- YTX: This designates a high-performance, sealed AGM (Absorbed Glass Mat) battery made by Yuasa, the original equipment manufacturer (OEM). Many other brands use this same prefix for their equivalent batteries.
- 7: This number relates to the battery’s power output or capacity. It’s a performance rating.
- L: This is crucial. It stands for “Left” and indicates that the negative terminal is on the left side when you’re looking at the front of the battery. Getting a “YTX7-BS” without the “L” will mean your cables won’t reach.
- BS: This indicates the battery is shipped with the acid in a separate container and needs to be filled and sealed by the user or retailer before installation (Bottle Supplied).
Physical Dimensions: Why a Perfect Fit Matters
Beyond the part number, the physical dimensions are critical. The battery tray on the DS 450 is designed for a specific footprint. A battery that’s too big won’t fit, and one that’s too small will vibrate excessively, leading to premature failure.
A standard YTX7L-BS battery has the following approximate dimensions:
- Length: 4.43 inches (113mm)
- Width: 2.75 inches (70mm)
- Height: 5.12 inches (130mm)
Always double-check the dimensions of any replacement battery against these numbers to guarantee a snug, secure fit.
Key Electrical Specs: Volts, Amps, and CCA
The numbers on the side of the battery are its vital signs. Here’s what to look for:
- Voltage: Your DS 450 runs on a 12-volt system. This is standard for nearly all ATVs.
- Capacity (Ah): This is Amp Hours, which measures the battery’s storage capacity. A YTX7L-BS is typically around 6 Ah. This tells you how long it can deliver a certain amount of current.
- Cold Cranking Amps (CCA): This is arguably the most important number. CCA measures the battery’s ability to start an engine in cold temperatures (0°F / -18°C). The DS 450 engine requires a good kick, so look for a battery with at least 100 CCA. Higher is often better, especially if you ride in colder climates.
Your 2008 Can-Am DS 450 Battery Size Guide: Choosing the Right Type
The OEM YTX7L-BS is an AGM battery, but you have options. Understanding the benefits of 2008 Can Am DS 450 battery size choices will help you pick the perfect power source for your riding style. Let’s compare the main technologies.
Conventional Lead-Acid (The Old Standard)
These are the old-school, “wet cell” batteries. They require you to periodically check and top off the electrolyte levels with distilled water. While they are the cheapest option, they are not ideal for off-roading.
The constant vibration and potential for tipping over make them prone to leaking dangerous battery acid. We at FatBoysOffroad strongly recommend avoiding this type for your DS 450.
AGM (Absorbed Glass Mat): The Go-To for Off-Roading
This is the technology of the stock YTX7L-BS battery. The electrolyte is absorbed into fiberglass mats, making the battery spill-proof and highly vibration-resistant. This is exactly what you need for hitting trails, jumps, and whoops.
AGM batteries are maintenance-free, offer excellent CCA for their size, and provide a fantastic balance of performance, durability, and cost. For most riders, a quality AGM battery is the perfect choice.
Lithium (LiFePO4): The Lightweight Performance Upgrade
If you’re a racer or a performance junkie looking to shed every possible ounce, a Lithium Iron Phosphate (LiFePO4) battery is the ultimate upgrade. These are incredibly lightweight—often saving 3-5 pounds compared to a lead-acid equivalent.
They also offer higher cranking amps, a longer service life, and a very low self-discharge rate (meaning they hold a charge for months). The main downsides are a higher upfront cost and potential sensitivity to very cold temperatures or improper charging. You must use a lithium-specific battery charger.
How to Replace Your 2008 Can-Am DS 450 Battery: A Step-by-Step Guide
Ready to get your hands dirty? This section covers how to 2008 Can Am DS 450 battery size your replacement and install it safely. Following these steps will ensure a smooth and trouble-free swap.
Tools and Safety Gear You’ll Need
Gather your gear before you start. You don’t need much:
- Safety Glasses & Gloves
- Socket set or wrenches (typically 8mm or 10mm for terminal bolts)
- Phillips head screwdriver
- Wire brush or battery terminal cleaning tool
- Battery terminal protector spray (optional but recommended)
Step 1: Locating and Accessing the Battery
On the 2008 Can-Am DS 450, the battery is located under the seat. Simply remove the seat by unlatching it at the rear. You’ll see the battery secured in its tray, usually by a rubber strap or a small metal bracket.
Step 2: Safe Removal of the Old Battery
This is the most critical safety step. Always disconnect the negative terminal first.
- Using your wrench, loosen the bolt on the NEGATIVE (black, “-“) terminal. Wiggle the cable off and tuck it away from the battery post to prevent accidental contact.
- Next, loosen the bolt on the POSITIVE (red, “+”) terminal and remove the cable.
- Unfasten the hold-down strap or bracket.
- Carefully lift the old battery straight out of the tray.
Pro Tip: Why negative first? If your wrench touches the frame while you’re loosening the positive terminal (with the negative still connected), you’ll create a short circuit. Sparks will fly! Removing the negative first breaks the circuit and makes the process much safer.
Step 3: Preparing and Installing the New Battery
Before you drop the new battery in, take a moment to clean the battery tray and the cable terminals with a wire brush. Good, clean connections are key to reliable power.
- Place the new battery into the tray, ensuring it sits flat and secure.
- Secure the hold-down strap or bracket.
- Now, connect in the reverse order of removal: POSITIVE first. Attach the red cable to the positive (“+”) terminal and tighten the bolt snugly.
- Attach the black cable to the negative (“-“) terminal and tighten its bolt.
- Give both cables a gentle tug to ensure they are tight and won’t vibrate loose. Apply terminal protector spray if you have it.
Step 4: Final Checks and Startup
With the new battery installed, replace the seat. Turn the key to the “on” position and check that your lights and display power up. If all looks good, hit the starter. Your DS 450 should fire right up with newfound energy.
Common Problems with 2008 Can-Am DS 450 Battery Size and Fitment
Even with the right part number, things can sometimes go wrong. Here are some common problems with 2008 Can Am DS 450 battery size and how to solve them.
“My New Battery Doesn’t Fit!” – Terminal and Dimension Issues
Sometimes, budget brands can have slight variations in case size or terminal design. If the battery is too tall, it might interfere with the seat. If the terminals are shaped differently, the stock bolts might not fit. This is why we recommend sticking to reputable brands like Yuasa, MotoBatt, or Antigravity for a guaranteed fit.
“The Quad Won’t Start” – Troubleshooting Post-Installation
If you have no power after installation, the first thing to check is your connections. Are the terminals tight? Did you accidentally leave a main fuse disconnected? Also, ensure you didn’t mix up the positive and negative terminals, which can cause serious electrical damage.
Premature Battery Failure: What’s Killing Your Power?
If you’re replacing batteries every year, you may have an underlying issue. A faulty voltage regulator/rectifier could be overcharging or undercharging the battery. You could also have a “parasitic draw”—an electrical component that’s drawing power even when the key is off. A multimeter can help you diagnose these more complex issues.
The 2008 Can-Am DS 450 Battery Size Care Guide: Maximizing Lifespan
A good battery can last 3-5 years or more with proper care. This 2008 Can Am DS 450 battery size care guide will help you get the most out of your investment. Following these best practices is key to long-term reliability.
The Importance of a Battery Tender for Off-Season Storage
If your ATV sits for more than a few weeks, especially in the winter, the battery will slowly self-discharge. A smart battery tender (like a Battery Tender Jr. or NOCO Genius) is essential. It monitors the battery’s voltage and delivers a slow, safe charge only when needed, preventing sulfation and keeping it ready to go.
Keeping Terminals Clean and Corrosion-Free
Every few months, check your battery terminals for white, fuzzy corrosion. This buildup acts as an insulator and restricts electrical flow. Clean it off with a wire brush and a mixture of baking soda and water. A clean connection is a happy connection.
Regular Voltage Checks: Your Battery’s Health Report
A simple multimeter can tell you a lot. A fully charged 12V AGM battery should read around 12.8 volts or higher with the engine off. If it consistently rests below 12.4 volts, it’s losing its ability to hold a charge and may need replacement soon.
Sustainable and Eco-Friendly 2008 Can-Am DS 450 Battery Size Options
Being responsible riders means thinking about our environmental impact. Let’s talk about sustainable 2008 Can Am DS 450 battery size choices and proper disposal.
The Environmental Impact of Lead-Acid Batteries
Traditional batteries contain lead and sulfuric acid, which are highly toxic if they end up in a landfill. They can contaminate soil and groundwater, posing a serious environmental hazard.
Proper Battery Recycling: It’s the Law and the Right Thing to Do
Never, ever throw an old battery in the trash. Nearly all of its components can be recycled. When you buy a new battery, the auto parts store or dealership will almost always take your old one for free. It’s an easy and incredibly important step to protect our riding areas and communities.
Are Lithium Batteries a Greener Choice?
This is a complex question. Lithium batteries don’t contain toxic heavy metals like lead. They also last much longer, meaning fewer batteries are consumed over the life of the vehicle. However, the mining and processing of lithium have their own environmental considerations. The best eco-friendly practice is to maximize the life of whatever battery you choose through proper care and always recycle it correctly at the end of its life.
