I am a lame (*&%. I left my dome light and the two map lights on either side of it, on all night last night. From like 5pm to 12 Noon today! DOH! So, anyway, the car wasn't dead. I am a fairly new owner to a Prius and don't know how I may have hurt the battery life? I drove it today and it went from two bars back up to only missing one bar when I got where I was going. I got back into the car after that stop and it was back down to two bars again, until I drove it again for a bit. Did I mess up my battery life or do you think it is ok? Thanks!!!! PS: how much is a new battery nowadays for an '06?
