Troubleshooting Poor Battery Runtime

  1. Check if the Battery is the Issue
    Try another fully charged battery in the tool to confirm whether the problem lies with the battery or the tool.
  2. Avoid Continuous Full-Power Operation
    Running the tool at maximum speed unnecessarily drains the battery faster.
    • Use the appropriate power setting for your task.
    • Lower the speed setting when possible, to conserve battery life.
       
  3. Check Battery Size and Suitability
    • This tool performs best with a 4Ah battery or higher for optimal runtime.
    • The higher the Ah rating, the longer the runtime.
    • If you are using a smaller capacity battery and the tool cannot complete the task, upgrade to a larger battery.
