So I am wondering about my 12v battery health. I wonder if that battery is low, does the hybrid battery pack somehow supplement vehicle accessory power? I have noticed a few times that after driving the car and parking over night that the traction battery bar graph is down to about 2 bars on my display the next day. I would think it would hold a charge longer than 12 hours to where it wasn't all the way down at startup. I also notice that when I go through a car wash and the car is neutral for a few minutes, I get the "TRACTION BATTERY LOW" warning to put the car in park or drive so the engine can charge the hybrid battery back up.

Traction battery charges the battery in READY mode (only). As the capacity of both is quite different I don't understand why it goes to LOW. Are you sure you wash the car?

cjityy - you can give him a picture of the 3rd wire. I am just getting a Lexus battery installed for $400 next week. Btw, I did go to Sears and they had no clue about what to do with the 3rd wire. They suggested I should go back to the dealer.

Typically, I leased the cars and returned them in 3 years. After many years, I have a 5 year old car, which might go to 8 year old or even longer..
Back to battery.. as I wrote in preceding, disconnecting 3rd wire causes warning lamps to go on! I don't know how so many people are using optoma, die hard etc. batteries!

There are no signs that it is going bad. In fact the dealer said that the test shows that the battery is fine. How ever, since it is 5 years old, I am having it replaced. I don't want to take the risk.. Its only $400 and I certainly don't want to jump start the car in Wisconsin winter at ANY time..

They must be using some type of loop back to continue continuity or something...I think our battery doesn't have as much stress as other batteries in the engine bay or on a standard gasoline only system. No heat stress being in the trunk (compared to engine being next to it, the startup is always electrical only which then fires off the gas if the traction battery is too low. I'm not paying $400 until it starts to show signs, I can use that money for other things, but then again..since you own two of these like it's nothing, probably nothing but a thing for you lol
I sold my 2nd 600h. I have only one now. I replaced the other one with a Jaguar xjl. The xjl is absolutely stunning.. It is very eye catching and has an amazing curb appeal..
Back to the 600h, I live in Milwaukee..
You are probably correct.. Battery might last 6 or 7 years.. but.. The way I saw it, I think I would probably keep the car for another 4 years easy.. I have to change it anyway, probably as soon as next year.. So, might as well change it now.. and not worry about a bad winter. This battery will last till the end of life (with me) of this car. I hope you will work with lxurious to help him find the 3rd wire in his car. He is the only person who has successfullly installed the after market battery.. It would be very useful information to others, as these cars get older..

Yea I'd like to help out anyway I can someone just upload a pic with the 3rd wire circled or pointed out. My aftermarket sound has a few extra wires that kinda confuse me. But both were installed professionally so I wouldnt have first hand knowledge.

According to the other Rx and Prius hybrid forums, they have installed a standard battery that matches size and terminal position of the starter battery with no problem. In fact, one user installed a Optima Yellow Top battery which is a deep cycle gel battery that allows greater capacity to run accessories while the car is off. They are used by many with amps and stereo setups. The hybrid system uses the inverter to convert the high power down to 12 volts that provides the charge back to the battery in the trunk. So, with that said, I plan on doing the Optima Red Top or Yellow top when it is time for me to change mine. I found all that out by taking some time on google and researching posts by actual people who have done it. And even the Yellow Top battery is much cheaper than the factory battery which appears to be nothing more than a standard 12v battery found in cars, just perhaps a smaller form factor to fit in the trunk
So.. What do you plan to do with the 3rd wire? My lexus dealer installed the Interstate battery. Warning lights came on the dash (forgot which ones). They had to remove the interstate battery. I also tried disconnecting the third wire (while keeping the panasonic battery in place). I got warning lights (forgot which ones). They went away only after I reconnected the 3rd wire and after I disconnected and reconnected the panasonic battery.
I sent the picture of the 3rd wire to lxurious.. Hopefully, he will come back with the answer.
As for me, I have already changed my battery with a factory panasonic (i think it was around $500 including installation).. I am continuing this thread only for public interest.
