My Buying Guides on Yamaha Yfz 450 Battery Size
When I was looking to replace the battery on my Yamaha YFZ 450, I quickly realized that knowing the right battery size is crucial for a smooth fit and reliable performance. Here’s what I learned from my experience, and I hope it helps you find the perfect battery for your ride.
Understanding the Importance of the Correct Battery Size
Getting the right battery size means your YFZ 450 will start easily, all electrical components will function properly, and the battery will fit snugly without any modifications. Using the wrong size can cause issues like loose connections, damage from vibrations, or even electrical failures.
What Is the Standard Battery Size for Yamaha YFZ 450?
From my research and experience, the Yamaha YFZ 450 typically uses a 12-volt battery with a size close to YTX14-BS or an equivalent. This battery size is common for many sport ATVs and provides the right balance of power and dimensions. The physical dimensions are roughly:
- Length: about 5.2 inches (132 mm)
- Width: about 3.4 inches (86 mm)
- Height: about 5.6 inches (142 mm)
Keep in mind, always double-check your owner’s manual or existing battery label to confirm these dimensions.
Battery Specifications to Consider
Besides size, I paid attention to these key specs:
- Voltage: Yamaha YFZ 450 requires a 12V battery.
- Cold Cranking Amps (CCA): A higher CCA rating helps with quick starts, especially in cold weather. I aimed for at least 180 CCA.
- Amp Hour (Ah) Rating: This indicates how long the battery can deliver power. A 12Ah rating is typical for this model.
Types of Batteries Suitable for Yamaha YFZ 450
During my search, I found several battery types that fit the YFZ 450:
- Lead Acid (Conventional): These are affordable but require maintenance like topping up electrolyte.
- AGM (Absorbed Glass Mat): More expensive but maintenance-free, spill-proof, and resistant to vibration. I personally prefer AGM for durability and convenience.
- Lithium-ion: Lightweight and powerful, but often pricier and sometimes require a special charger.
Tips for Buying and Installing Your Battery
- Check Fitment: Even if the specs match, physically test the battery fit if possible.
- Secure Properly: Use the battery hold-down and terminals recommended by Yamaha to avoid damage from vibrations.
- Charge Before Use: New batteries may not come fully charged, so I always charged mine before installing.
- Recycle Old Battery: Don’t throw away your old battery; take it to a recycling center or retailer that accepts used batteries.
Where I Found Good Deals on Yamaha YFZ 450 Batteries
I found the best deals online through ATV parts stores and platforms like Amazon or eBay. Sometimes local powersports shops have OEM batteries in stock. Comparing prices and checking for warranty coverage helped me make a confident purchase.
Final Thoughts
