Hey guys! Today, we're diving deep into everything you need to know about the 2011 Can-Am Renegade 800R battery. Whether you're facing a dead battery, looking to upgrade, or just want to understand how to maintain it, this guide has got you covered. Let's jump right in!

Understanding Your 2011 Can-Am Renegade 800R Battery

First, let's talk about why the battery is so crucial for your 2011 Can-Am Renegade 800R. The battery is the heart of your ATV's electrical system. It provides the necessary power to start the engine, run the lights, operate the electronic fuel injection (EFI), and keep all the other electrical components running smoothly. Without a healthy battery, you're not going anywhere. Understanding the specific requirements of your ATV's battery ensures you get the best performance and longevity.

Key Battery Functions

• Starting the Engine: This is the most obvious job. The battery delivers a high current to the starter motor, which cranks the engine until it starts.
• Powering Electronics: Once the engine is running, the battery supports the electrical system by powering lights, the instrument panel, and other accessories.
• Stabilizing Voltage: The battery acts as a buffer, smoothing out voltage fluctuations from the charging system to protect sensitive electronic components.

Battery Specifications for the 2011 Can-Am Renegade 800R

It's essential to know the exact specifications required for your ATV. Using the wrong type of battery can lead to poor performance or even damage to your vehicle's electrical system. Typically, the 2011 Can-Am Renegade 800R uses a 12-volt battery with a specific Cold Cranking Amps (CCA) rating. The CCA rating indicates the battery's ability to start the engine in cold temperatures. Always refer to your owner's manual for the precise specifications, but a common replacement is a YTX20L-BS type battery. These batteries are designed to withstand the rigors of off-road use and provide reliable power.

Common Battery Issues

• Dead Battery: The most common issue, often caused by leaving the lights on, infrequent use, or a faulty charging system.
• Slow Cranking: Indicates a weak battery that's struggling to provide enough power to the starter motor.
• Battery Not Holding Charge: Could be due to sulfation, age, or a parasitic drain in the electrical system.
• Corrosion: Buildup on the terminals can impede current flow.

Choosing the Right Replacement Battery

Okay, so your old battery is giving you trouble, and it's time for a replacement. What do you need to consider? Picking the right battery is crucial for optimal performance. You want something reliable, durable, and perfectly suited for your 2011 Can-Am Renegade 800R. Let’s break down the key factors.

Types of Batteries

• Conventional Lead-Acid Batteries: These are the most affordable option but require regular maintenance, such as checking and refilling the electrolyte levels. They are less resistant to vibration and extreme conditions.
• Absorbent Glass Mat (AGM) Batteries: AGM batteries are sealed, maintenance-free, and more resistant to vibration and shock. They also have a longer lifespan and better performance in cold weather compared to conventional batteries. These are a popular upgrade for ATVs.
• Lithium Batteries: Lithium batteries are the most expensive but offer significant advantages, including a much lighter weight, higher energy density, and longer lifespan. They are ideal for riders looking for maximum performance and weight reduction.

Key Considerations When Buying a Replacement

• CCA (Cold Cranking Amps): Ensure the replacement battery meets or exceeds the CCA rating specified in your owner's manual. A higher CCA rating means better starting performance in cold conditions.
• Size and Fit: The battery must fit properly in the battery compartment. Check the dimensions to ensure a snug and secure fit.
• Terminal Type and Placement: Make sure the terminals match the type and placement of your old battery. Incorrect terminals can make installation difficult or impossible.
• Brand and Reviews: Research different brands and read reviews to find a reliable and reputable battery. Popular brands known for their quality include Yuasa, Odyssey, and Duracell.

Recommended Batteries for 2011 Can-Am Renegade 800R

• Odyssey PC925: A high-performance AGM battery known for its exceptional cranking power and long lifespan. It's a great upgrade for riders who demand the best.
• Duracell AGM Battery: A dependable and affordable AGM battery that provides excellent value for the money.

Battery Maintenance Tips

Keeping your battery in top condition will extend its life and ensure reliable performance. Regular maintenance is key to avoiding unexpected breakdowns and keeping your 2011 Can-Am Renegade 800R running smoothly. Proper maintenance is not just about keeping the battery clean; it's about ensuring optimal performance and longevity.

Regular Checks

• Check the Terminals: Inspect the battery terminals for corrosion. Clean them with a wire brush and a mixture of baking soda and water if necessary. Apply a battery terminal protector spray to prevent future corrosion.
• Check the Battery Voltage: Use a multimeter to check the battery voltage. A fully charged 12-volt battery should read around 12.6 volts. If the voltage is significantly lower, the battery may need to be recharged or replaced.
• Inspect the Battery Case: Look for any signs of damage, such as cracks or swelling. A damaged battery case can lead to leaks and reduced performance.

Charging Your Battery

• Use a Proper Charger: Use a battery charger specifically designed for AGM or lithium batteries, depending on the type of battery you have. Avoid using a car battery charger, as it may overcharge and damage the battery.
• Slow and Steady: Charge the battery at a slow rate to avoid overheating and damaging the cells. A trickle charger is ideal for maintaining the battery's charge during storage.
• Avoid Overcharging: Disconnect the charger once the battery is fully charged. Overcharging can shorten the battery's lifespan.

Storage Tips

• Disconnect the Battery: If you're storing your ATV for an extended period, disconnect the battery to prevent parasitic drain. This will help maintain the battery's charge and prevent sulfation.
• Store in a Cool, Dry Place: Store the battery in a cool, dry place away from direct sunlight and extreme temperatures. This will help prolong its lifespan.
• Use a Battery Maintainer: A battery maintainer, also known as a trickle charger, will keep the battery at its optimal charge level during storage. This is especially useful for AGM and lithium batteries.

  • Old Battery: Batteries have a limited lifespan and will eventually lose their ability to hold a charge.
  • Parasitic Drain: A faulty electrical component may be drawing power from the battery even when the ATV is turned off.
• Troubleshooting Steps:
  • Charge the Battery: Use a battery charger to fully charge the battery. If it still won't hold a charge, it may be time for a replacement.
  • Check for Parasitic Drain: Use a multimeter to check for a parasitic drain. Disconnect the negative battery cable and connect the multimeter in series between the cable and the battery terminal. A reading higher than 50 milliamps indicates a parasitic drain.
  • Replace the Battery: If the battery is old or shows signs of damage, replace it with a new one.

Problem 2: Slow Cranking

• Possible Causes:
  • Weak Battery: The battery may not be providing enough power to the starter motor.
  • Corroded Terminals: Corrosion on the battery terminals can impede current flow.
  • Faulty Starter Motor: The starter motor may be drawing too much current or not functioning properly.
• Troubleshooting Steps:
  • Check the Battery Voltage: Use a multimeter to check the battery voltage while cranking the engine. A voltage below 10 volts indicates a weak battery.
  • Clean the Battery Terminals: Clean the battery terminals with a wire brush and a mixture of baking soda and water.
  • Test the Starter Motor: Have the starter motor tested by a professional mechanic to ensure it is functioning properly.

Problem 3: Battery Keeps Dying

• Possible Causes:
  • Faulty Charging System: The charging system may not be charging the battery properly.
  • Loose Battery Connections: Loose battery connections can cause intermittent charging and power loss.
  • Short Circuit: A short circuit in the electrical system can drain the battery quickly.
