Like the title states Im having battery issues on my 2018 with 5k on the clock. She is pretty much stock. No mods. Today she left me stranded for the first time but I have had a few close calls this summer. I had to call my wife and have her come jump me. Yes you can jump with a car just leave the car engine turned off. The MT started right up and off I went.
Now here's the rub. I've never owned a bike that has left me stranded before (never) and I have owned 10 or so street bikes to date. First time for everything I guess.
I've also never have had to put a battery tender on a bike over summer. Usually charge it up in the Spring and call it good. My Suzuki's/Honda's have always started no matter what. Maybe its the factory battery that's the issue IDK. I have noticed unless the battery is fully charged it sometimes struggles to start.
Anyone else having issues? Might be time for a better battery unless it's an electrical issue.

Sounds like it's time for a new battery. Motorcycle batteries are only reliably good for about 2 years. Anytime you start to have such issues with any bike and the battery is more than 2 years old, the first step should be to replace the battery or at least test it to eliminate it as the issue before you move onto diagnosing other things.
It could of course be something else but best bet is to deal with the battery first. Whether testing it with a multimeter or just deciding to buy a new battery.
There's a lot of misconceptions about battery and battery tenders. As I understand the way that bikes and their batteries work, any period of time that batteries sit the battery will obviously start to drain. When bikes remained in this drained state over even longer periods of time (could be as little as a couple weeks) they start to sulfate which starts to decrease the maximum charge a battery can hold. The batteries current 100 % charge after this sulfation occurs becomes what a new batteries 80 % is. If it happens again, the new 100 % becomes what would normally be 60 %. And so on and so forth, to where it can't even hold enough charge to start the bike.
Even bikes that are ridden a lot but only on short trips can experience the same, as the bike might not be ridden long enough to reach full charge, leaving a partially drained battery that can be exposed to sulfation
What's been working for me, if I don't anticipate riding for 2 weeks or more, I take the battery out of the bike (or disconnect it), run it on the tender until it reaches full charge, then leave it out of the bike and off the tender until I'm ready to ride again. No drain & fully charged = less chance of sulfation to occur & longer lasting batteries.

Thanks for the input.
Bought an AGM xtreme from batteries plus. See how that goes.
Mine was toast.

I ordered a YTZ10S and the polarity was reversed from my OEM Yuasa from 2017. A search on the net shows them all to be that way. I found the YTZ7S has the correct polarity, 130CCA. I found a guy on another forum who has run the YTZ7S in his Busa, another 1190CC bike, and a liter bike for years with no issues. Guess I'm gonna try that

You have to lay the battery down on it's side. It's not suppose to be upright otherwise it's as you mention. The stock battery is on it's side from the factory.

Mine was upright, but I will look at that idea. Every one I've seen on video is the same as mine. Fast forward a bit in this video

Yep. The battery is actually on it's side. If you look closely at the video you will notice the writing on the battery is face up meaning is laying on it's side. I actually just put a new battery in my MT10. It's an Xtreme AGM and it also went back in on it's side. Perfect fit.

That's why the battery has two different ways to connect it on the same post.
