I guess the question is for your ace prius mechanics. I purchased a 06 prius that was hit in the front......hard. I repaired it but have noticed that there is a voltage drop in the started or small battery of about .4 volts per day when connected. if not connected no drop, therefore there is some drain going on.
I've looked at car at night to see if a light or something is on and nothing. I have yet to run the car for more than a few minutes.......getting ready for paint......any ideas?
