There’s nothing worse than gearing up for a big ride, hopping on your Renegade, hitting that starter button, and hearing nothing but a soul-crushing ‘click’. A dead battery can kill a perfect day on the trails before it even begins.
We’ve all been there. That moment of frustration is a universal experience for off-roaders. But what if you could turn that frustration into confidence?
This comprehensive can am renegade 800 battery guide promises to do just that. We’re going to break down everything you need to know, from choosing the perfect replacement to performing the installation yourself. You’ll learn maintenance secrets, troubleshoot common issues, and ensure your machine has the reliable power it needs to conquer any terrain.
Why Your Can-Am Renegade 800 Battery is More Than Just a Box
It’s easy to think of your battery as just the thing that starts your ATV. But on a modern machine like the Renegade 800, it’s the heart of the entire electrical system.
Your battery doesn’t just crank the engine. It powers the Electronic Control Unit (ECU), fuel injection system, headlights, taillights, and any accessories you’ve added. Think about that winch, those LED light bars, or that GPS unit—they all rely on a steady stream of power from a healthy battery.
Understanding Battery Types for Your Ride
Not all batteries are created equal, especially when it comes to the abuse of off-roading. Here are the main types you’ll encounter:
- Conventional Lead-Acid: The old-school standard. These are often the cheapest option but require periodic maintenance, like topping off with distilled water. They are also prone to spilling, which is a major drawback on a machine that’s rarely level.
- AGM (Absorbent Glass Mat): This is the most common and highly recommended type for powersports. The acid is absorbed into fiberglass mats, making the battery spill-proof and highly vibration-resistant. It’s a fantastic, reliable choice for the trail.
- Lithium (LiFePO4): The premium, high-performance option. Lithium batteries are incredibly lightweight (often saving 5-10 lbs), have a very long lifespan, and provide strong, consistent cranking power. The main downside is their higher upfront cost.
Choosing the Right Can-Am Renegade 800 Battery: A Buyer’s Guide
When your original battery finally gives up, picking a replacement isn’t as simple as grabbing the first one you see. Understanding a few key specs will ensure you get the right power and fit for your machine.
Key Specs You MUST Understand
Look for these numbers on any potential battery. They tell you everything about its performance.
- Cold Cranking Amps (CCA): This is the measure of a battery’s ability to start an engine in cold weather. A higher CCA is always better, especially if you ride in chilly conditions.
- Amp Hour (Ah) Rating: This tells you about the battery’s capacity. A higher Ah rating means it can run your accessories for longer without the engine running before it goes flat. This is crucial if you use a winch frequently.
- Dimensions (L x W x H): This seems obvious, but it’s a common mistake. Measure your old battery or your battery tray to ensure the new one will physically fit without modification.
AGM vs. Lithium: The Off-Roader’s Dilemma
For most Renegade 800 owners, an AGM battery is the sweet spot. It offers excellent vibration resistance, is maintenance-free, and provides a significant upgrade in reliability over a conventional battery without breaking the bank.
However, if you’re a performance-focused rider looking to shed every possible pound or you need the absolute best starting power, a lithium battery is worth the investment. The weight savings are noticeable, and they can often last two to three times as long as an AGM battery with proper care.
How to Replace Your Can-Am Renegade 800 Battery: A Step-by-Step Guide
Swapping out the battery is a straightforward job you can absolutely do yourself with basic tools. This section covers exactly how to can am renegade 800 battery replacement is done safely in your own garage.
Safety First: Essential Tools and Precautions
Before you start, gather your gear and get in the right mindset. Safety is non-negotiable.
- Tools Needed: A socket set (typically 8mm and 10mm sockets), a Phillips head screwdriver, a wire brush, and battery terminal cleaner.
- Safety Gear: Always wear safety glasses and gloves. Battery acid is corrosive, and sparks are a real risk.
- Location: Work in a well-ventilated area. Batteries can release flammable hydrogen gas.
Step 1: Locate and Access the Battery
On most Can-Am Renegade 800 models, the battery is located under the seat. You’ll need to remove the seat to gain access to the battery cover and hold-down strap or bracket.
Step 2: Disconnect the Old Battery (The Right Way)
This is the most critical step for safety. Follow this order precisely to prevent dangerous sparks.
First, use your wrench to loosen and remove the bolt on the NEGATIVE (-) terminal. This is the black cable. Tuck the cable away from the battery post so it can’t accidentally make contact.
Second, loosen and remove the bolt on the POSITIVE (+) terminal. This is the red cable. Now the battery is fully disconnected.
Step 3: Remove the Old Battery and Clean Up
Remove the hold-down bracket or strap. Carefully lift the old battery out of the tray. This is a great time to clean the battery tray and the cable terminals with a wire brush and some terminal cleaner to ensure a perfect connection for the new battery.
Step 4: Install the New Battery (The Reverse Order)
Place your new battery securely in the tray and install the hold-down bracket.
Now, you’ll connect the terminals in the reverse order of removal. Attach the POSITIVE (+) red cable first and tighten the bolt securely.
Finally, attach the NEGATIVE (-) black cable and tighten its bolt. Applying a thin layer of dielectric grease to the terminals can help prevent future corrosion.
Step 5: Final Checks and Startup
Reinstall the battery cover and the seat. Turn the key and fire up your Renegade. It should start right up. Let it run for a few minutes to allow the charging system to top off the new battery.
Common Problems with Can-Am Renegade 800 Battery Systems
Sometimes, a dead battery isn’t the battery’s fault. If you’re having persistent electrical issues, one of these culprits might be to blame. This is where you can troubleshoot some common problems with can am renegade 800 battery systems.
Parasitic Drain: The Silent Killer
A parasitic drain is when an electrical component continues to draw power even when the key is off. This can be caused by a faulty accessory or a short in the wiring.
A simple test involves using a multimeter set to measure amps between the disconnected negative cable and the negative battery post. A small draw is normal for the ECU’s memory, but a significant draw points to a problem you’ll need to hunt down.
Charging System Woes
Your ATV has its own generator (the stator) and a voltage regulator/rectifier that work together to charge the battery while the engine is running. If either of these components fails, your battery will not charge, and even a brand new one will quickly die.
You can test this with a multimeter. A healthy charging system should show about 13.5 to 14.5 volts at the battery terminals when the engine is running at a fast idle. If it’s below 13 volts, you likely have a charging system issue.
The Ultimate Can-Am Renegade 800 Battery Care Guide
Want to maximize the life of your battery and avoid getting stranded? Follow these can am renegade 800 battery best practices for a long and happy partnership with your power source.
The Power of a Smart Charger/Tender
The single best thing you can do for your battery, especially during the off-season, is to use a smart battery tender. Unlike a simple charger, a tender monitors the battery’s voltage and only applies a charge when needed, preventing overcharging and keeping it in peak condition.
Regular Inspections are Key
Every few rides, take a quick look at your battery. Make sure the terminals are clean and tight. A loose connection can mimic a dead battery and prevent proper charging. Ensure the battery is securely fastened in its tray.
Sustainable and Eco-Friendly Can-Am Renegade 800 Battery Practices
Being a responsible rider extends to how you dispose of old parts. A lead-acid battery is highly toxic and must never be thrown in the regular trash.
The good news is they are almost 100% recyclable. Any auto parts store or shop that sells batteries is required by law to accept your old one for recycling, often giving you a small credit (a “core charge”) for doing so. This is a simple and effective way to practice sustainable can am renegade 800 battery disposal.
