    My 2006 Prius battery is not holding a charge very well. About a month ago I had rodents in the engine and had both my stereo and wiring harness replaced at the dealer. I've noticed that every morning the Energy Monitor screen shows only 2 purple cells left in the battery. It always recharges as I'm driving it, but then it loses its charge after siting still a few moments. No idiot lights are on. I've done the DIY system check mode and everything says OK, except audio- it shows "check" in red. Also, my 12v battery is at 11.9. (I replaced my original 12v battery several months ago with no problems).

    Could my stereo or wiring harness have been installed wrong? image.jpg

    Welcome to PriusChat! Since the dealer just worked on the stereo and the audio shows a red "check" as in the photo, I would get that fixed first. Good luck!
