Why the 2015 Harley Davidson Ultra Limited Battery Size Is Necessary
When I first looked into the battery size for my 2015 Harley Davidson Ultra Limited, I quickly realized how crucial it is to have the right one.

Overall, sticking to the recommended battery size for my 2015 Ultra Limited gives me peace of mind. It keeps the bike’s electronics functioning properly, supports the powerful engine start-up, and helps avoid any roadside surprises.

My Buying Guides on 2015 Harley Davidson Ultra Limited Battery Size
When I first needed to replace the battery on my 2015 Harley Davidson Ultra Limited, I quickly realized how important it was to get the right size and type. Here’s what I learned through my experience that can help you make the best choice.
Understanding the Battery Size for 2015 Harley Davidson Ultra Limited
The Ultra Limited model from 2015 typically requires a battery that fits specific dimensions and delivers the correct power output. From my research and experience, the standard battery size for this bike is a Group 24 or 24F. This size ensures it fits perfectly into the battery compartment without any modifications.
Battery Specifications to Look For
When I bought my replacement battery, I made sure to check:
- Voltage: 12 volts is standard for this model.
- Cold Cranking Amps (CCA): Around 450-600 CCA is ideal to guarantee reliable starts, especially in colder weather.
- Reserve Capacity: A higher reserve capacity means the battery can power your bike’s electronics longer if the charging system fails. I aimed for at least 20 minutes.
Types of Batteries Suitable for the Ultra Limited
I found there are mainly two types of batteries to consider:
- Lead-Acid (Conventional): These are more affordable but require regular maintenance like checking water levels.
- AGM (Absorbent Glass Mat): These are sealed, maintenance-free, and more vibration-resistant, which I preferred given the riding conditions.
My Tips for Choosing the Best Battery
- Check your owner’s manual: Always verify the recommended battery specs.
- Opt for quality brands: I went with brands known for durability and good warranty support.
- Consider your riding environment: If you ride in cold climates, prioritize higher CCA ratings.
- Look for maintenance-free options: AGM batteries have been a hassle-free choice for me.
Installation and Maintenance Insights
Installing the battery on my Ultra Limited was straightforward, but I made sure to:
- Disconnect the negative terminal first to avoid shorts.
- Secure the battery firmly to prevent vibrations.
- Use dielectric grease on terminals to prevent corrosion.
For maintenance, if you choose a conventional battery, regularly check the electrolyte levels and keep terminals clean. For AGM batteries, just keep them charged and clean.
Final Thoughts
Getting the right battery size and type for your 2015 Harley Davidson Ultra Limited made a huge difference in reliability and performance for me. By following these tips, you can avoid common pitfalls and enjoy smooth rides with peace of mind.
