Hey guys, sorry for all the dumb questions. I tried searching and googling but I couldn't find much, as you can tell I'm not a bright one. I need to buy a Yamaha R6 Battery because my old one is kinda dead, its been dead for 4-5 month. I charged it for about 5 hours and the battery tender said it was good, after 2 weeks or so of leaving it there and riding it around the parking lot the battery is dead once again. I'm guessing that means I need a new battery. Also, I checked out a place called NAPA they sell Yamaha 2003 R6 batteries, they're alot cheaper then the ones from other motorsport dealers. Should I go buy the more expensive one? or the cheaper one? does it really matter? and do they come charged? Thanks alot guys.
