Battery issues after I charged using regular trickle charger

I got this '20 Iron 1200 and it may have been an anomaly of some sorts because the battery died not long after getting it, or I guess since I got it secondhand I should have expected that already. But I didn't, because the first owner said they just replaced it to an OEM battery so I got nothing to worry about.

Well, it died in the middle of a city ride, thankfully not an expressway one. So what I did was use my charger on it because I thought, aren't all batteries rechargeable? I made it worse. Apparently, you're not supposed to do that. So again, while in the middle of a ride, it died and I almost got into an accident.

Question, is my battery beyond repair now? I checked and it's really OEM but I might have ruined it for the worst.

That sucks. I guess the best way to go about it is to grab a fresh OEM battery and don't risk another breakdown. If it does that in the city, what more for long drives?
 
If the previous owner put a new OEM battery into the bike and it still died I would look for a reason why the battery is going dead. You might have a charging issue. Could be some bad wiring or loose connections. You'll have to do a bit of digging and use a multimeter to check voltage to see that things are working the way they're supposed to.

Another thing to check is if you're using a battery maintainer, make sure it is compatible with your battery type. If you connect the wrong maintainer to a battery (like AGM) you can ruin the battery. I still think your first issue is figuring out why your battery isn't charging or what is always drawing power that shouldn't be.

Hope this helps
 
Glad you didn't end up in an accident. Unfortunately, yeah, if the battery died mid-ride and then again after charging , its likely toast at this point. Even if it is an OEM battery, if it sat too long unused or was overcharged with the wrong charger, it can go bad fast. Since it's secondhand, the "just replaced" part could be true, but there's no telling how it was stored or maintained. Best bet now is to replace it with a quality new one and check your charging system while you're at it
