The Polaris Sportsman 450 takes the Group U1 case. The Antigravity Group U1 RE-START is a drop-in for that case: 925 cranking amps, 8 lb, a built-in jump start that saves enough charge to get you home. Polaris fits a Group U1 battery (part 4017419, 340 CCA) to this model. U1 and U1R differ only in terminal position; match the layout of the battery you are replacing.

The Sportsman 450 is an ATV where the battery changed mid-run: 2006 to 2020 takes the YTX14AH-BS and 2021 to 2026 the Group U1. 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 2021 to 2026 that means the Antigravity Group U1 RE-START: 925 cranking amps, 8 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. Polaris fits a Group U1 battery (part 4017419, 340 CCA) to this model. U1 and U1R differ only in terminal position; match the layout of the battery you are replacing. Charge it with a lithium-compatible charger or maintainer for the off-season and it outlasts the lead-acid battery it replaces by years.
