Shop all Polaris ATV batteriesWhy the year matters on this one
The Sportsman 90 is an ATV where the battery changed mid-run: 2001 to 2002 takes the YTX4L-BS, 2003 to 2013 the YTX5L-BS and 2014 to 2016 the ATX12-AH. 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 2014 to 2016 that means the Antigravity ATX12-AH RE-START: 360 cranking amps, 3 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.
