The 12-volt battery in your lawn tractor is a smaller version of an automotive battery. When the tractor battery is discharged, you can charged to its full capacity with an automotive battery charger unless the battery was frozen or is at the end of its useful life.

Charging Time

The battery can be charged at a maximum rate of 10 amps for one hour. If your charger is less than 10 amps, it is recommended that you charge the battery for a longer period of time. As an example, a 2-amp charger may take up to 5 hours to fully charge a tractor battery.


  1. Ensure that your charger is set at 12 volts. For specific details, please follow the manufacturer instructions for your charger.

  2. The battery can be in the tractor when you charge it. Make sure that the battery charger is off and unplugged before connecting it to the battery.

  3. Connect the red charger cable to the positive (+) terminal of the battery. 

  4. Connect the black charger cable to the negative battery terminal.

  5. Following the instructions for your battery charger, turn on or plug in the charger.

  6. Charge the battery following the instructions specified by your battery charger manufacturer. Once the battery is fully charged, turn off the power on the charger. Then remove the charger cables.

  7. Start the tractor. 

To extend the life of the battery, the battery should be fully charged before storing the tractor for long periods.
