I have a problem that is difficult to describe. I have a 2020 Heritage Softtail for just over a year and it's been amazing. I've really had no issues with the bike, other than one problem that seems to have creeped up. Around Halloween I was doing a scavenger event riding to different areas and validating with pictures. I got to one location, shut down the bike, spent about 5 minutes looking around and snapping photos. Hopped back on the bike and hit the button and for a brief second, the bike was dead. A second later (don't think I even let up on the button) the bike slowly turned over and then fired up ... sort of like an old car with a worn down battery. I thought nothing of it at the time figuring it was 100+ degrees outside, the bike was hot and it only spent about 5 minutes cooling. Perhaps pistons swelled or something. The biggest annoying is that the clock reset, which tells me the entire electrical was drained for a brief second.
Fast forward, it's now December and it's happened about a half dozen more times, two times in the past week. I now fear I have a growing problem I have no idea how to diagnose, nor can I find anything about it online. It's not a problem I can create/recreate. It just happens. It's also happened when the bike was completely cold. I use a battery tender so I know the battery is fully charged. Given the battery is now 3 years old I guess I could look at replacement but that's an outright guess as to the issue.
Anybody have any experience with this type of issue?
1. Take the batter out and get it load tested at a couple of your local auto parts stores or batteries + store.
2. The battery can be fully charged and have good voltage but not enough amperage to start the bike.
3. Heat kills batteries and shortens their useful life.
4. Report back after the load test.
5. Lots of people experience this type of issue, first rule out the battery then we can go from there.
It is good advice. I just haven’t made time yet to pull the battery and have it tested somewhere. Need to figure out where. Not to mention they don’t make it that easy to get to. Will get it done though.

Ok, just got back from having two load tests done at two different places. Neither gave me numbers to report but both declared the battery extremely healthy and move than enough load for what my Softtail is rated. Nice to know it's good, but also frustrating that I still have a problem.
It's happened when it's both cold and hot. I don't think when it's fully cold but I know it's happened when the bike was sitting for a couple of hours. I don't recall it happening as I pull out of the house... but again, it's only happened a half a dozen times.
The bike is a 2020 114/M8. It's has about 13-14K miles on it, 6k of which I put on in the last year since I bought it in December of 2022.
9 out of 10 times, you need a new battery. They can give you all sorts of test results that they are good, but they you get stranded. Battery is almost 4 years old, I bet a new one from the MoCo and she fires right up. Good luck.
If it were mine, I'd replace the battery just because of the age. No fun being stranded due to an old battery. And since you can't recreate the problem with any confidence, that would be one item that is due for replacement you can eliminate.
