Essential Winter Storage Guide for Powersports Batteries

As a powersports vehicle owner, protecting your vehicle during the winter is important. Whether it’s a motorcycle, ATV/UTV, or jet ski,  properly storing and maintaining your vehicle's battery during the winter months means that you’ll be able to hit the road, trails, or water faster when the weather cooperates. In fact, proper maintenance and storage of your powersports vehicle's battery is crucial for ensuring optimal performance and longevity, especially when the cold sets in. 

Extreme cold can have a significant impact on battery health, potentially causing damage if left unchecked.

In this guide, we’ll dive into essential winter battery storage tips for various powersports vehicles, helping you avoid common pitfalls and maximize battery life. For more general guidance on off-season storage, check out our Off Season Storage Guide.

Why Winter Battery Maintenance is Crucial

Winter weather can take a heavy toll on your powersports vehicle’s battery, especially if proper maintenance steps aren’t followed. Without proper storage, the cold temperatures cause the batteries to lose charge more quickly, potentially leading to a frozen battery if the charge is too low. 

When that happens, it can lead to permanent damage, reducing the battery’s lifespan and, in some cases, rendering it unusable.

In addition to the cold, leaving your battery inactive for long periods without regular charging can result in sulfation—where lead sulfate crystals build up on the battery’s plates, reducing its ability to hold a charge. This can happen to both AGM and conventional batteries,  if not stored and maintained properly.

By taking the right precautions, such as keeping your battery charged and stored in the right conditions, you can prevent these problems and ensure your vehicle is ready to go when you are.

How to Ensure Battery Longevity During Winter

To keep your battery healthy over the winter, it’s important to take the right steps and stay consistent with your maintenance. Here are key actions to extend the life of your powersports vehicle’s battery:

  • Check for Correct Installation: Whether you are planning on removing the battery for storage, or keeping it in your vehicle, review your Manufacturer’s Guide to make sure that your battery is installed in the correct orientation, if it is not, carefully remove the battery and reinstall with the specific installation instructions found in the guide.
  • Clean and Protect the Battery: Any buildup on your terminals could decrease your batteries performance or reduce longevity. Start with an inspection of your terminals, clean off any build up, and apply a terminal protectant to prevent corrosion. This keeps the battery in good working order for quick reinstallation and avoids power issues when you're ready to use it again.
  • Use a Battery Maintainer: Keep your battery connected to a maintainer that regulates the charge. This prevents it from dropping below an optimal level, which can happen during long storage periods.
  • Monitor Charge Levels Regularly: Even with a maintainer, it's good practice to periodically check the battery's charge. If the battery drops below 12.4 volts, charge it back up to avoid sulfation.
  • Store in Ideal Conditions: Always store your battery in a cool, dry place, away from direct sunlight or extreme cold. Consistent room temperature conditions prevent charge loss and freezing, especially for vehicles that are stored for long periods.

These steps ensure your battery stays healthy throughout the off-season and is ready to go when you are.

Common Winter Battery Storage Mistakes

While preparing your powersports vehicle for winter, there are a few easy-to-overlook mistakes that can cause long-term damage. Avoiding these pitfalls will help you get the most out of your battery and ensure it performs well when you're ready to ride again:

  • Assuming AGM Batteries Don’t Need Attention: It’s a common misconception that AGM (Absorbed Glass Mat) batteries require no attention during winter storage. Although you don’t need to check fluid levels, AGM batteries still need to stay charged. Leaving them idle all winter can lead to reduced performance, shorter lifespan, or a dead battery.
  • Skipping a Charger: Many riders believe that simply storing the battery in a cool, dry place is enough. In reality, even a slight charge loss can lead to sulfation, shortening the battery's life. Using a battery maintainer or trickle charger during winter ensures it will stay ready at full capacity.
  • Incorrect Battery Orientation: Especially in snowmobiles and PWCs, where batteries are sometimes installed at odd angles, it’s important to ensure the battery is installed in the correct orientation during storage or reinstallation. This prevents potential acid leaks or damage.
  • Not Cleaning Before Storage: Some riders skip cleaning the battery terminals before storage, leading to corrosion buildup. Corroded terminals can reduce battery efficiency and complicate reinstallation.

By taking these precautions, you can prevent unnecessary damage or replacement, ensuring your battery is in peak condition when the season changes.

Winter Battery Storage Tips for Different Vehicle Types

An ounce of prevention is worth a pound of cure, as they say, and a bit of preparation keeps your powersports vehicle ready for action when the season changes. While many tips apply across all vehicle types, there are still some key differences depending on whether you’re storing a motorcycle, ATV/UTV, or PWC/Jet Ski.

Motorcycles

  • Keep the Battery Charged: Use a battery maintainer or trickle charger to ensure the battery stays charged throughout the winter. This prevents it from discharging and losing capacity.
  • Clean the Terminals: If you notice corrosion or buildup on the terminals, clean them using a solution of baking soda and water to ensure optimal performance when you’re ready to ride again.
  • Check Fluid Levels for Flooded Batteries: If you have a conventional battery, check the electrolyte levels and top off with distilled water as needed. This prevents sulfation and ensures the battery stays in working condition.

ATVs/UTVs:

  • Storage Not Always Required: Many riders continue to use their ATVs and UTVs during the colder months. If that’s the case, make sure to periodically check the battery’s charge, especially after long rides in freezing temperatures, and charge with a maintainer as needed.
  • Store Properly if Not in Use: For those storing their vehicles, follow the same steps as with motorcycles: keep the battery charged and clean, and check fluid levels if using a conventional battery.

PWCs/Jet Skis:

  • Clean and Inspect: Before storing your battery, clean the terminals and inspect for any signs of damage or corrosion that could affect performance when summer comes around.
  • Long-Term Storage Considerations: Since PWCs are often only used in the Summer, it's important to remove the battery and store it in a cool, dry place. Once safely removed and stored,  connect it to a battery maintainer to keep the charge steady.

For snowmobile owners, particularly Ski-Doo riders, be sure to review our Ski-Doo Battery Fit Guide for common installation and fit challenges.

Taking these steps helps ensure your vehicle's battery stays in working condition during winter, reducing the risk of damage and increasing its longevity. There are, however, some common issues riders deal with when storing or replacing their batteries.
