The Polaris Sportsman 800 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.

Why the year matters on this one

The Sportsman 800 is an ATV where the battery changed mid-run: 2005 to 2010 takes the YIX30L and 2011 to 2014 the ATX20. The plate above names the source for each year, and the table shows every run we have on file, so match the year to the case before you order.

For 2011 to 2014 that means 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 800 take?+
It depends on the year: 2005 to 2010 takes the YIX30L and 2011 to 2014 the ATX20. For 2011 to 2014 that is the Antigravity ATX20 RE-START, the lithium drop-in for the ATX20 case. The table above shows every run we have on file, so match your year to the case before you order.
Will a lithium battery work in a Sportsman 800 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.
