The Polaris Sportsman XP 850 takes the YTX20HL 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.

Shop all Polaris ATV batteriesWhy the year matters on this one
The Sportsman XP 850 is an ATV where the battery changed mid-run: 2009 takes the YIX30L, 2010 to 2014 the ATX20 and 2015 to 2021 the YTX20HL. 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 2015 to 2021 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. Charge it with a lithium-compatible charger or maintainer for the off-season and it outlasts the lead-acid battery it replaces by years.
