My Buying Guides on 2015 Harley Davidson Ultra Limited Battery Size
When I was looking to replace the battery on my 2015 Harley Davidson Ultra Limited, I quickly realized that choosing the right battery size is crucial for optimal performance and longevity. Here’s what I learned from my experience that can help you find the perfect fit for your bike.
Understanding the Battery Size for 2015 Harley Davidson Ultra Limited
The 2015 Ultra Limited typically uses a Group Size 14 battery. This size is fairly common among Harley touring models and ensures the battery fits snugly in the designated compartment without any modifications. Knowing this upfront saved me a lot of time and hassle.
Why the Right Battery Size Matters
I initially thought any motorcycle battery would work, but the wrong size can cause poor connections, vibration damage, or even electrical issues. The Group Size 14 battery not only fits perfectly but also provides the correct voltage and amp-hour rating that my Ultra Limited demands.
Checking Battery Specifications: Voltage and Capacity
My Ultra Limited requires a 12-volt battery, which is standard for most motorcycles. Additionally, I looked for a battery with at least 18-20 amp-hours (Ah) capacity and around 270-300 cold cranking amps (CCA). These specs ensure reliable starts even in colder weather.
Types of Batteries to Consider
When I replaced my battery, I had three main options:
- Conventional Lead-Acid: Affordable but requires regular maintenance and venting.
- AGM (Absorbed Glass Mat): Maintenance-free, spill-proof, and offers better vibration resistance, which is great for long rides.
- Lithium-Ion: Lightweight and long-lasting but more expensive and sometimes requires a special charger.
I chose an AGM battery for the balance of durability and convenience.
Tips for Buying Your Battery
- Confirm Group Size: Always check your owner’s manual or existing battery label to confirm Group Size 14.
- Look for Reputable Brands: I opted for brands known for motorcycle batteries like Yuasa, Odyssey, or Shorai.
- Check Warranty and Lifespan: A good warranty gives peace of mind, especially if you ride frequently.
- Consider Your Riding Style: If you do a lot of stop-and-go or cold-weather riding, prioritize higher CCA ratings.
Installation and Maintenance Advice
Once I got the right battery, installation was straightforward. I made sure to disconnect the negative terminal first and reconnect it last to avoid shorts. Periodically, I check the terminals for corrosion and keep them clean for the best connection.
—
In summary, knowing that the 2015 Harley Davidson Ultra Limited requires a Group Size 14, 12V battery with solid CCA and Ah ratings helped me make an informed purchase. Whether you choose AGM or another type, the right size and specs will keep your bike running smoothly for miles to come.
