Hi Jim,

I just got back from the a 12 days trip and attempted to start my Prius which has been sitting in an unheated garage. When I tried to start it, there was no response, so I used jumper cables to start it which worked right away. I ran in the house to get something, and when I came back out, the tail lights were dim and the car would not start again. Once again, I used another car to jump start it, and the same thing happened - about 4 minutes later, even after taking it up and down the street, it died after sitting idle again.

The Prius is a 2010, but already has 42,000 miles on it. I leave it on a lot, and sit idle because of my work. Before I left for my trip, I noticed the power was lacking slightly - but enough to notice.

Is it possible the 12V batter is dying? Thanks, Aaron

No its not dying its done dead. Sulphated and history. Stop jumping it as you may do irreparable damage to the Inverter.
