Somebody selling a bike or a car often says some part is new and what that usually means is they put it in sometime within that last 6-8months. So if they don't show a receipt, "new" is just marketing.
Since it's a wet battery, like Hoss said, have you checked the water level in it?
Also, you can take it, (the battery) to any auto parts store and they can load test it for you to tell you if its good, close to bad, or bad. Usually this load test is free.
If the battery is failing a charger won't help, and if a battery is failing and as it continues to fail it will take the R/R and stator out with it. So getting it load tested ASAP is a very good idea, if you're not in a position to replace it. At least then you know and you can avoid riding it and causing more damage.
Another thing about the wet battery's is the acid coming out of the vent reeks havoc on parts of the bike you can't see easily, as well as more electrical components, including the junction box. So a visual check behind the side covers and of the water level is another good "do it now" suggestion.
And not for nothing, my bike starts charging the battery just after I open the throttle, and it's also to suggested that not doing to many "parade rides" (idle rolling) because at idle it's not charging, but it does start before 3k rpm, or at least it should.
Just some stuff to think about. Let us know what you find.
