This is quoted from a 2024 HD Owners Manual...
Charge the battery when:
• Motorcycle lights appear dim.
• Electric starter sounds weak.
• Battery has not been used for two weeks or more.
If only the battery would last for two weeks. My experience with my new 2025 Road Glide is that over a week is problematic now. I had the battery light come on and stay on after not riding the bike for 8 days.
My previous 2020 and 2015 Road Glides could go two weeks with no issues. Though I tended to go a week at a time, whether dependent. I tend to ride in the winter as well as an aside.
I actually finally decided to start an account here (not much of a forum person in general) because of the issues I'm seeing with the battery. It looks like with this current generation of touring Harleys (RGs & SGs) that you probably need to make sure you go out once every five days or less.
Anything after that feels like a crap shoot. I think HD needs to take a closer look at efficiency of their electronics and in particular when shut down. Either that or increase the power storage of the batteries. I shouldn't need to hook it up to a tender after a week.
I'm starting to think that maybe after the ride I should just remove the circuit breaker if I'm not going to go out for a over a week. Which with this new generation would get old since you need to remove the saddle bag first before you can remove the side cover.
Don't get me wrong, this bike is pretty awesome, a large difference between it and the previous generations of Road Glides. Though I miss my heated hummock seat. (Come on HD gets off your backside and bring out the hummock seat for the new generation of RG's and SG's)
