With A DeWalt 12V Battery.... I left the hatch up for a few days because I didn't drive it due to hot weather. The battery died on me of course. The dead battery measured 6.59v No amount of "battery recovery" time is going to recover it to start up the Prius. I charged up an old DeWalt 12V NiCad battery. I jump started the Prius with it. When I power down the Prius, the interior lights went back to really dim. The video is continuous one shot.
