Bad battery?

I have a 2014 Sportsman 570. It set most of the summer and when I went to crank it up for the first time a few weeks ago I had to charge the battery and then it cranked up just fine. Yesterday I went to crank it up and when I turned the key all that came on was the pod it wouldnt ever try to turn over. The break lights wouldnt come on nor would the head lights however my light bar would come on and my winch would operate. Ive let it sit all night on the battery charger and the same thing is going on. Has anyone else had this happen to them with a dead battery? I really dont want to take it to the dealer but if a new battery wont fix the issue I might have to bit the bullet and take it there. I am going to pick up a new battery today in hopes that since my battery is 2 years old that its just a simple battery swap and its fix.
