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

Antigravity Group U1 12V UTV Battery 925CA w/ Re-Start: The Automotive Case Yamaha and Kawasaki Put in Their Side-by-Sides, in Lithium

Yamaha builds the YXZ1000R, Viking and Wolverine around a Group U1 battery, the same automotive case that starts a Kawasaki Mule Pro-FX and Pro-FXT, the Teryx, and Polaris's new Ranger SP 570. It is a big, heavy lead-acid battery for a machine that already weighs plenty. Antigravity's Group U1 RE-START is the lithium version: a 20Ah pack with 925 cranking amps at 7.25 lbs, in a case that usually weighs 25 to 30.

This is Antigravity's automotive RE-START line, so the jump start is wireless: if a winch, a light bar or a month in the shed 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 side-by-side

• 925 cranking amps, up to three times a lead-acid U1: it starts the first time, cold morning or opening day
• Wireless RE-START: keyfob-activated jump start from a held-back reserve when the machine 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
