Antigravity Group U1R 12V Lawn Mower Battery 925CA (w/ Re-Start, Right Positive)

Antigravity Group U1R 12V Lawn Mower Battery 925CA: The Riding Mower and Tractor Battery, in Lithium, With a Wireless Jump Start

Nearly every riding mower, lawn tractor and zero-turn built in the last thirty years starts on a Group U1: John Deere, Cub Cadet, Craftsman, Husqvarna, Toro, Troy-Bilt, Kubota, Exmark, Scag. It is also the battery in the Kawasaki Mule Pro-FX and Pro-FXT, the newer Polaris Sportsman 450 and 570, the Yamaha YXZ1000R, small generators and a Mazda Miata. Antigravity's Group U1R RE-START is the lithium version of that battery: a 20Ah pack with 925 cranking amps at 7.25 lbs, in a lead-acid case that usually weighs 25 to 30.

This is Antigravity's automotive RE-START line, so the jump start is wireless: if the battery ever runs itself 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.

Why the Group U1R in your mower

• 925 cranking amps, up to three times a lead-acid U1R: it starts the first time in April
• Wireless RE-START: keyfob-activated jump start from a held-back reserve when the mower sat all winter
• 7.25 lbs; sealed, no acid, mount in any orientation
• Exact BCI Group U1R case, 7.75 x 5.2 x 7.3 inches, positive terminal on the RIGHT, 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
