Replying to: glouderback (Aug 31, 2009 4:33 pm) I figured out what my wife was doing that caused the beeping. She was simultaneously pulling on the door handle and pushing the lock button when opening the door causing the Prius to put out a steady tone for about 6 seconds. I replaced the 12 volt battery anyway, as I don't want her getting stranded because of 5 year old battery.

Based upon the last few messages in this thread, I ordered a yellow 12V battery and their Prius kit from eLeanAid. I have not had a problem with my 2004 Prius but it has been on my mind and I am curious about the reported mileage improvements. I can use the old battery to start my backup generator. It will arrive next week.
