Yes, the entire process to generate a battery certificate takes just a few minutes. You can easily install it in your car without tools or the need for a mechanic. Simply:

  1. Plug Voltest into the OBD-II port, typically located under the dashboard on the left side.
  2. Download and run the Power Check Control app (available on iOS and Android).
