I need some help on replacing the battery in my 2015 Sportsman 570sp. My battery says its a 4011138. Which I find says 14AH ETX15. I go to the Polaris website and under parts I punch that number in and it says this is NOT the right model battery for your machine. They claim the 4140006 is the correct battery. I think this battery is the one you need to add water to where mine is sealed. What I really want to do is find a good replacement battery like the Deka but cant figure out exactly which model of battery to get. This sizes don’t quite match what I measured mine at. Granted I didn’t pull the battery out and the ones I see are all a tad bigger which if it didn’t have to fit in the tray exactly would be fine. I’m trying to get a high power battery that will handle the power steering and the winch/snowplow with power angle without giving up the ship and losing the power steering when I really would like to have it. For those of you who had the above battery in your 2015 570sp what did you replace it with and the model number. The search has came up with to many choices that don’t seem to fit mine. Thanks for your help.
