HV Battery Failure.... please help

I've got a 2005 battery on my shop floor that I removed from my August-wrecked Prius. I've been meaning to put it in my replacement Prius to keep it charged but just haven't gotten around to doing that. If you aren't in a hurry, you could wait until I determine if it's servicable, or if you want, you could pay shipping and find out if it's any good on your nickel, then pay me the fair market price if it does you any good. Also, I'd suggest you get another opinion on your battery as that is a very rare failure. Were you watching battery stats on the display? Did it seem Ok, then fail suddenly? If so I'd suspect some other component is at fault. Check in with the tech portion of this site on these questions.

Do you have HID headlights? If so, it could be a failing bulb.

 

You have 145k miles. Remember that on a normal car, you probably would have had to have the transmission repaired at a similar cost.

 

Besides the traction battery and the HID headlight, have you had other problems?

True, the complexity of the Toyota hybrid system does not lend itself to longevity without the occasional repair now and then.

If you bought a GM or Chrysler there's some chance you would have had your major repair well before 145K miles...

Now that you've restored the 2004 to operation (other than the HID bulb) do you plan to sell the car or are you going to keep driving it until the next failure happens?

 

300 k miles on a Prius without any major repairs is quite good result. Normal expected lifespan of hybrid battery is around 200 k miles.

Modern turbo charged diesel cars have even lower lifespan before major repairs. Maybe if you get some old school non turbo charged diesel & manual transmission car. But performance and economy in latter ones will suck bigtime.

I recommend you call Mac's Service Center in Ashland, Va
My co worker had her Prius Hv Battery done there. They even cleaned the car when done and gave her a longer warranty than the dealer offered. I looked it up on Google they have great reviews.

 

The OP posted that over two years ago. Do you really think that they still haven't fixed it yet? Or are you just spamming?

 

Not a spammer saw it pop up yesterday. HV Battery Failure need help. Not sure why it said that for a current day yesterday. I responded when I saw it. No worries just trying to be helpful. I am new to this forum.

 

Ok no problems Prefer a prius. I understand you were just trying to help.

Spammers often like to dig up old threads. I guess someone probably spammed this thread, which made it current, and then the spam was subsequently deleted. This happens sometimes.

Peace.

 

No, they don't specifically check the 12v battery. A standard system check might show slightly low voltage but they might miss it. They did on my 1st gen car. Only found out the 12v was weak (8 years old) after it died in an oil change bay when the tech left the ignition turned on and tranny in nuetral. On 1st and 2nd gen Prius you can check the 12v voltage yourself with the onboard system check feature in the touch display. On my 2002 Prius I have to set the park brake (to keep the DRL's off) and turn the key to acc, tap a certain corner of the display four times and it enters system check. Do a google on this, you should be able to find instructions, that's how I found it. If I recall you want to see voltage stay above 10.2volts?? not sure about that.
Several times over the years my 2002 Prius has shown hybrid vehicle battery warning lights. A phone call to the service department at Toyota reassured us it's a "glitch" in the early Prius's (Prii). Sometimes a jiggle of the wiring harness on the main battery will solve it. One time recently these warning lights came on because the car was steered tightly into a parking space and then parked on a slant tilting to the left. We moved the car to a level parking spot and the lights went away.
