The GAU1 is a 12V Group U1 flooded starting battery for compatible lawn mowers, garden tractors, and small-engine equipment. Skip the auto parts store, avoid arranging a tow, and leave the delivery-day heavy lifting to us.

Starting power for lawn and garden equipment

With 340 cold cranking amps and 425 cranking amps, the GAU1 supplies the short burst of power needed to start compatible engines. Its 41-minute reserve capacity and compact U1 case make it an option for equipment that specifies this battery format and rating.

Check fit before ordering

Match the voltage, dimensions, hold-down, terminal position, and required starting rating to your equipment manual and existing battery. U1 and U1R terminal layouts differ; do not choose by case size alone. This is an engine-starting battery, not a replacement for a deep-cycle traction battery in an electric mower. Contact DIYBattery with your equipment make, model, and current battery photo if you need help selecting the right replacement.
