  • Arrives 100% charged — Unbox, drop-in, and go. No downtime.
  • 30-Day Money-Back — If it doesn’t outperform your old battery, send it back.

Compatibility & quick fit

Common in GR-U1 trays used by Cub Cadet, John Deere, Husqvarna, MTD, Toro and more.

  1. Measure your tray (L×W×H) and compare to the dimensions.
  2. Confirm terminal polarity (see U1 vs U1R note).
  3. Check hold-down/strap clearance above 7.2″ / 184 mm.

U1 vs U1R: U1 typically has positive on the left when terminals face you; U1R is reversed. Match your cable reach.

Terminal hardware: standard 6 mm square-nut style; fits common mower/UTV ring terminals.
