to prevent the battery from draining? I usually run the vacuum for about 15 minutes, but someone told me i am supposed to run the car engine when i do this, or i will destroy the car battery.

    if you were to drain the battery to the point of dead or half dead alot it will ruin the battery life, it will not last as long, a car battery is not designed to be totally drained and recharged over and over, thats called deep cycling, thats why a car battery in a boat will not last long, a boat battery is called a deep cycle marine battery, its designed to be drained dead and recharged over and over again,
