My Buying Guides on Yamaha Big Bear 400 Battery

When I decided to replace the battery in my Yamaha Big Bear 400, I realized there are several factors to consider to ensure I choose the right one. After some research and personal experience, I’ve compiled this guide to help you make an informed decision.

Understanding Battery Types

One of the first things I learned is that not all batteries are created equal. The Yamaha Big Bear 400 typically requires a sealed lead-acid (SLA) battery, specifically a maintenance-free type. While shopping, I found that there are two main types to consider:

  1. AGM (Absorbent Glass Mat) – This type is known for its durability and resistance to vibration, which is crucial for off-road riding. I found that AGM batteries tend to have a longer lifespan and better performance in extreme weather conditions.
  1. Conventional Lead-Acid – These batteries are generally cheaper but require regular maintenance, such as checking water levels. I opted against this type due to the hassle and potential for leaks.

Key Specifications

When I was comparing batteries, I paid close attention to the specifications. Here are the key specs I recommend you consider:

  • Voltage: The Yamaha Big Bear 400 typically requires a 12V battery. Make sure the battery you choose matches this voltage to ensure proper functionality.
  • CCA (Cold Cranking Amps): This is a critical measurement, especially for colder climates. A higher CCA rating means better starting power in low temperatures. I found that a CCA of around 200 is suitable for the Big Bear.
  • Dimensions: Battery size matters! I measured the battery compartment in my Big Bear to ensure that the new battery would fit snugly. Check the dimensions of the battery and compare them with your ATV’s battery tray.

Brand Recommendations

Through my experience, I found several reputable brands that produce high-quality batteries for the Yamaha Big Bear 400. Here are a few that stood out:

  • Yuasa: Known for their reliability and long-lasting performance, Yuasa batteries are a popular choice among ATV enthusiasts. I have had good experiences with their products in the past.
  • Batterytender: This brand offers AGM batteries that are specifically designed for ATVs and motorcycles. They are durable and come with a great warranty.
  • Shorai: If you’re looking for something lightweight and powerful, Shorai’s lithium-ion batteries might be worth considering. I found them to be pricier but they offer excellent performance.

Where to Buy

I explored various options for purchasing my Yamaha Big Bear 400 battery. Here are a few places that I found helpful:

  • Local Motorcycle or ATV Dealerships: I visited a few dealerships and found that they often carry the specific battery I needed, plus the added benefit of knowledgeable staff.
  • Online Retailers: Websites like Amazon, Battery Mart, and Cycle Gear provide a wide selection of batteries, often at competitive prices. Just be sure to read reviews before making a purchase.
  • Automotive Stores: Stores like AutoZone and O’Reilly Auto Parts sometimes stock batteries suitable for ATVs, and I appreciated the convenience of being able to pick up the battery the same day.

Installation Tips

Once I had my new battery, I wanted to ensure a smooth installation. Here are some tips based on my experience:

  1. Safety First: Always wear gloves and safety goggles when handling batteries to avoid any acid exposure.
  1. Disconnect the Old Battery: Start by disconnecting the negative terminal first, followed by the positive terminal. This helps prevent any electrical shorts.
  1. Connect the New Battery: When installing the new battery, connect the positive terminal first, followed by the negative.
  1. Secure the Battery: Make sure the battery is secured in place to prevent movement while riding.

Maintenance Tips

To prolong the life of my battery, I adopted a few maintenance habits:

  • Regular Charging: I invested in a good quality battery maintainer to keep the battery charged during the off-season.
  • Clean Connections: I periodically check the battery terminals for corrosion and clean them as necessary.
  • Check Fluid Levels: If I had chosen a conventional battery, I would have regularly checked the electrolyte levels.

Purchasing a new battery for my Yamaha Big Bear 400 was a straightforward process once I understood what to look for. By considering the type, specifications, brand, and where to buy, I was able to find the perfect battery that met my needs. Plus, with a little maintenance, I’m confident my new battery will keep my ATV running smoothly for years to come!
