The Polaris Sportsman WV850 takes the ATX20 case. The Antigravity ATX20 RE-START is a drop-in for that case: 680 cranking amps, 4 lb, a built-in jump start that saves enough charge to get you home. Antigravity's list names the ATX20 for this model; Yuasa's guide names the YIX30L case for some trims. Go by the code on your old battery.

What the Sportsman WV850 needs, in plain English

Every Sportsman WV850 from the first 2014 model through 2014 starts on the ATX20 case, a 12-volt starter battery. Polaris ships it with a lead-acid battery that starts to fade after two or three seasons of short rides and off-season storage, and that is usually the day a rider goes looking for something better.

The lithium drop-in is the Antigravity ATX20 RE-START: 680 cranking amps, 4 pounds, the same case in lithium. Its RE-START function puts the battery to sleep before a parasitic draw can drain it, then wakes it with one press for a jump start. Antigravity's list names the ATX20 for this model; Yuasa's guide names the YIX30L case for some trims. Go by the code on your old battery. Charge it with a lithium-compatible charger or maintainer for the off-season and it outlasts the lead-acid battery it replaces by years.

What size battery does a Polaris Sportsman WV850 take?+
The ATX20 case, the same one on every Sportsman WV850 from 2014 to 2014. The Antigravity ATX20 RE-START is the lithium drop-in for it. Antigravity's list names the ATX20 for this model; Yuasa's guide names the YIX30L case for some trims. Go by the code on your old battery.
Will a lithium battery work in a Sportsman WV850 without changes?+
Yes, on a machine with a healthy charging system: the lithium battery uses the same case, the same posts and the same cables, and it drops in where the lead-acid battery sat. Check that the stator and regulator hold a steady charge, fill any gap in the tray with the foam spacers most lithium ATV batteries include, and match the terminal layout of the battery you are replacing.
Do I need a different charger for a lithium ATV battery?+
Use a charger or maintainer with a lithium (LiFePO4) mode. A lead-acid trickle charger can push the wrong voltage profile, and a desulfation mode can damage a lithium pack. A lithium-profile maintainer over the off-season keeps it topped without harm, and the battery loses only a few percent of charge a month sitting on its own.
