Antigravity Group U1 12V ATV Battery 925CA (w/ Re-Start, Left Positive)

Antigravity Group U1 12V ATV Battery 925CA w/ Re-Start: The Battery Polaris Put in the New Sportsman, in Lithium

For 2021 Polaris moved the Sportsman 450 H.O. and Sportsman 570 off the little YTX14AH and onto a full automotive Group U1 battery (Polaris part 4017419, 340 cold cranking amps). The two-up Touring 570 and the 6x6 followed in 2022. Antigravity's Group U1 RE-START is the lithium version of that battery: a 20Ah pack with 925 cranking amps at 7.25 lbs, in a case that usually weighs 25 to 30. Bolts into the same tray, same terminals, 20 pounds off the front of the quad.

This is Antigravity's automotive RE-START line, so the jump start is wireless: if the winch, a light bar or a month in the barn runs the battery down, the BMS sleeps it with a starting reserve held back, and a press of the keyfob remote wakes it up. No hood, no seat, no cables run from the truck.

Why the Group U1 in your Sportsman

• 925 cranking amps, nearly three times the OEM battery: it starts the first time, cold morning or opening day
• Wireless RE-START: keyfob-activated jump start from a held-back reserve when the quad sat all winter
• 7.25 lbs; sealed, no acid, mount in any orientation; shock and vibration resistant
• Exact BCI Group U1 case, 7.75 x 5.2 x 7.3 inches, positive terminal on the LEFT, M6 x 1 threaded terminals
• Full BMS: over-charge, over-discharge, thermal protection, cell balancing
• Holds its charge through the off-season; no tender required

Group U1 RE-START Specs for Nerds

Fits the Polaris Sportsman 450 H.O. and Sportsman 570 (2021 and later, all trims), Sportsman Touring 570 and 570 6x6 (2022 and later), Sportsman X2 570 (2025) and the Yamaha YXZ1000R. Terminals face you: if your positive post is on the right, you want the Group U1R version. A 2014 to 2020 Sportsman 570 takes the smaller YTX14AH case; that machine wants the Antigravity ATX12-AH. Adult signature required on delivery. Check your OEM code against the list above, and if you are not sure, we will confirm fitment before you order.
