After 5 years, the battery gave up the ghost on my Polaris 570 Sportsman. Whoever designed the battery placement on this model should be neutered. While I took many breaks because my old back couldn't stand the constant contortion, it took me 4 hours to complete the task. Aftermarket companies sell a kit to make it much easier. Why couldn't Polaris take a hint and do a better job of engineering? Maybe they have, mine is a 2015 model.
