Why the 2015 Harley Davidson Ultra Limited Battery Size is Necessary
From my experience, having the correct battery size for my 2015 Harley Davidson Ultra Limited is absolutely essential. The bike’s electrical system is designed to work with a specific battery capacity and dimensions to ensure reliable starting power and consistent performance. Using the right size battery means I never have to worry about my bike struggling to start, especially in cold weather or after long periods of inactivity.
Additionally, the Ultra Limited has numerous electrical components—like heated grips, infotainment systems, and lighting—that demand a steady and sufficient power supply. If the battery is too small, it simply can’t keep up with these demands, leading to dim lights or even unexpected shutdowns. On the other hand, a battery that fits perfectly in the designated compartment ensures secure mounting, preventing damage from vibrations during my rides.
In short, sticking to the recommended battery size for my Harley isn’t just about convenience; it’s about maintaining the bike’s overall reliability and my peace of mind on every journey.
My Buying Guides on 2015 Harley Davidson Ultra Limited Battery Size
When I was looking to replace the battery for my 2015 Harley Davidson Ultra Limited, I quickly realized that knowing the correct battery size and specifications is crucial for a smooth and trouble-free ride. Here’s what I learned through my experience that might help you choose the right battery for your bike.
Understanding the Battery Size for 2015 Harley Davidson Ultra Limited
The 2015 Ultra Limited typically uses a 12-volt battery, and the most commonly recommended size is a Group 24 battery. This size fits perfectly in the battery compartment and provides the necessary power for the bike’s electrical system, including the lights, ignition, and accessories. I made sure to double-check my owner’s manual and cross-verify with Harley Davidson dealer recommendations to confirm this.
Battery Type: Lead Acid vs. AGM
When I was choosing the battery type, I found that most stock batteries are lead-acid, but many riders prefer AGM (Absorbed Glass Mat) batteries for their Ultra Limited because they offer better vibration resistance, longer life, and are maintenance-free. Since my bike handles a lot of vibration on long rides, I opted for an AGM battery, which has worked great so far.
Cold Cranking Amps (CCA) and Reserve Capacity
I also paid attention to the Cold Cranking Amps (CCA) rating, which is important for starting the engine, especially in colder weather. For the Ultra Limited, a battery with at least 400-500 CCA is recommended. The reserve capacity is another number I checked; it indicates how long the battery can run the bike’s electrical system if the charging system fails. Having a good reserve capacity gave me peace of mind during longer trips.
Physical Dimensions and Fitment
Even though the Group 24 battery is standard, I measured the dimensions of my old battery to make sure the new one would fit perfectly. The approximate dimensions I found were around 10 inches in length, 6.8 inches in width, and 7.5 inches in height. It’s important to confirm this because a battery that’s too big or too small can cause installation issues or damage.
My Tips for Buying and Installing the Battery
- Always disconnect the negative terminal first to avoid shorts.
- Use dielectric grease on terminals to prevent corrosion.
- Secure the battery firmly in the compartment to prevent vibrations.
- Consider a battery tender or maintainer if you don’t ride frequently to keep the battery healthy.
Where I Bought My Battery
I found that buying from a reputable motorcycle parts dealer or directly from a Harley Davidson dealership ensures you get a genuine battery with proper warranty coverage. Online stores can offer good deals but always check the seller’s reviews and return policies.
Final Thoughts
Choosing the right battery size and type for the 2015 Harley Davidson Ultra Limited is straightforward once you know what specs to look for. I hope my experience helps you pick a battery that keeps your bike running reliably and smoothly. Safe riding!
