    A friend of mine called and told me his Prius suddenly stalled(gradually loss in power), while he was driving.

    According to him, he got someone with another Prius have the HV battery swapped from the working Prius to his own.

    His Prius didn't start. Eventually, they discovered each time they did the battery swapped, each of those batteries gets discharged within 5minutes.

    I have not being there to check it out yet.
    I'm thinking it might be the inverter system area.

    What do you guys think?
    Has anyone experienced this problem before?

    Do you have the 14 volts going to the 12 volt battery to keep it charged.
    Is there a hard bird battery actually charging
    did you try putting the engine inspection mode bypassing the Hybrid engine to see if it is the Hybrid engine or the battery and see if the engines working properly

    I'm not referring to the 12v battery, but the HV battery.

    The Hybrid battery charges the 12-volt battery so I was wondering if the inverter was working and not loading down your Hybrid battery
