Buying Guide

Match group size and terminal type

Confirm your mower's required group (U1, U1-CCA, ML-U1) and terminal style (NB/top post) to ensure plain swap-in compatibility

Consider CCA and starting power

Choose a battery with sufficient cold cranking amps (200–330 CCA in this list) for reliable starts in your typical temperature range

AGM vs sealed lead‑acid

AGM batteries offer better vibration resistance and maintenance-free performance, while SLA units can be a lower-cost option with similar voltage

Capacity and runtime matters

Higher amp-hour or CCA ratings generally yield longer starting life and better accessory support for electric PTOs and lights

Check compatibility with brand-specific mowers

Many batteries list fit for John Deere, Cub Cadet, Toro, and Craftsman—verify OEM part references to match mounts and hold-downs
