Prius (Gen 3) :: 12V Battery Is Dead - Cannot Jump Start

My 12V battery is dead- not sure what happened, I usually double press the lock button to turn the headlights off immediately. It seemed odd- the taillights were on, but not the headlights and all interior dome lights were on but dim. I certainly did not get the 'door open' warning beep when I left the car.

The car is completely dead - no power locks, interior lights etc. I tried to jump start it using the fuse box jumper plate, but was not successful. I have heavy duty jumper cables and it seemed like they only contacted the jump plate at one singular point, but that was the best I could do. It was touching, just only one point on the 'teeth' was physically on the front metal part. I waited a full 5 minutes with the donor car revving and tried to start it, but nothing at all. (And yes, I was + red to + red) I tried to adjust the cable on the plate a few times, but could not get any better of a grip. No dashboard light or anything ever came on- the car was just as dead.

What could the problem be? Should I try smaller cables for a better connection with the plate? How long should it generally take while revving the donor car? Or is this something more sinister?

Prius (2004-09) :: 2007 - Dead Battery Won't Jump Start

I have a 2007 Prius Package Six. I went away on vacation over Christmas and when I got back the battery was dead and the car wouldn't start. No problem as I was easily able to jumpstart it with a portable battery jumpstarter. However I kept having the same problem as apparently the battery wasn't maintaining a charge. So obviously my battery is kaput and needs replacing. I've watched the videos and plan on replacing it myself.

However when I went out this morning to jumpstart the car it wouldn't jumpstart at all. When I hook up my battery jumpstarter nothing happens. Nothing lights up. The car won't start. Even if my 12v battery is completely dead and cannot maintain a charge, shouldn't I still be able to get the car started with a jumpstart? I realize that as soon as I turn it off I will have to jumpstart again. But I can't figure out why a jumpstart won't even get the car fired up.Am I missing something?

Prius V :: Battery Dead - How To Jump And Not Go Into EV Mode

After 2 days of not using my Prius V, the 12v battery was dead. I couldn't figure out what I accidentally left on. I jumped it following the instructions in the manual but right after, it went into EV mode and then it required to be jumped again. I finally got the engine revving enough that it stayed on. I had never really listened to the engine rev before, but while revving it sounded higher pitched and tinny as compared to my old 6 cylinder, German car.

Is this higher pitched, tinny, electric sounding revving sound normal?
Is there anything to worry about after jumping the car?
Is there a way to see the charge on the battery? (In my old car if you hit specific buttons when starting you could enter a diagnostic mode where you could see many readings, live the current battery voltage. It would also be great if the tire pressure reading could be accessed this way.)

Also is it possible to use the hybrid battery to jump the car?

Lexus RX 2010-15 :: Dead Battery - Hatch Wouldn't Open After Jump

My wife's 2010 RX350 wouldn't start this morning. My guess is that the battery drained overnight with the back door ajar. After getting it started with a battery jump the rear hatch would not open by hand, the dash button or the key button. After driving and charging the battery the hatch would open. I'd this to be expected or an indication that perhaps the hatch has a fault?

Prius (2010-12) :: 12V Battery Fully Drained / Car Won't Jump Start Either

The 12V battery must have been drained completely over the weekend. None of the lights (interior and exterior) are working. The car won't start even using jumper cable. I guess the 12v battery must have some juice remaining to power up the computer in order to jump start the engine. Am I correct in this assumption?

My Prius is only a little over three years. What is the warranty on the 12v battery? I read that the OE battery is not the best. How long would I expect the OE 12v battery to last?

Toyota - Camry :: 2001 Will No Longer Start After Dead Battery And Jump

My wife left the lights on in the 2001 Camry and completely draining the battery. I tried to jump her but the car would not start (turns over great). Also the electrical system was strange in that the lights would not go off and other electrical items did not function. I disconnected the battery and fully recharged it and put it back on. I noticed that the "ALT" (100A) fusible link was blown and replaced it. Car still will not start (turns over great). The electrical problems appear fixed however the radio does not work. I tried to read the codes on the ODB and got "ERR". I checked all other fuses and they are good. I checked the pin-out voltage on the ODB port and was reading ~11.5V. I am wondering if I missed something like is the ECM bad? I can replace this myself for $150, but if I have it towed to a dealer it will cost me $800. Is there a way I can be sure that the ECM is bad, also are there other things to check that I may have missed. Also, when I turn the key to the "on" position, but do not start the car, the "Check engine" light does not illuminate.

Touareg :: 30 Hours Sitting Key Fob Not Working / Jump Start - Dead Battery?

I had left my car for about 30 hours without driving, which I've done before all winter with no issues. Went to start it up yesterday morning to head out and when the key FOB failed to open the door, I knew I was in trouble.

I unlocked the door manually, and put the key in to start it up and the Treg was completely dead and the key wouldn't release from the ignition. After a call to VW roadside assistance, and a jump start, it started right up and I dropped it off at the dealer for them to look at.

The service report says "diag and found low state of charge. charged battery and found passes tests. performed TSB 27-05-01 and cleaned ground point for battery. rechecked OK"

This is a V6 Touareg (there is a similar TSB I understand for V8s).

Passat (B6) :: 2006 - Battery Drained - Radio Remains Dead After Jump Start

I drove my 2006 Passat 2.0T at night a few days ago. And I forgot to shut off the light. It came out that my battery was drained completely. After doing a jump start under my friend's assistance, I was able to run it again. But my radio remains dead, meaning it won't turn on by all means.

Lexus RX 2010-15 :: Battery Discharging Too Often - Call For A Jump Start

I have a RX350 2012 model. Recently, in last 3 weeks my battery has discharged 3-4 times, I had to call for a jump start.

I got my battery checked with my dealership and they say the reports from battery are excellent!

I am not sure why is it discharging? I just think there might be a sensor failure which is keeping something running in my car.

Prius (2010-12) :: Traction Battery Keeps Getting Hot

This is my first year driving my prius during a hot season, and for past 3 weeks my mpg has dropped from 49 to 41-43 mpg, and the reason is my traction battery keeps getting HOT! I can hear the battery cooling fan turning on constantly at max when i reach 20 mph, my car doesn't want to start in EV mode the engine just kicks in no matter how light you press the throttle, the EV motor is not assisting with the engine, the infamous slow rpm drop keep occurring and I when to touch the traction battery case and it its HOT, Ive open up the case to check for any dust on the fan and ducts but so far its spotless. I really wished they place an AC vent for the battery because the back passenger area with full A/C doesn't t get as cold as the front dose which doesn't cool off the battery.

Prius (2010-12) :: Installing A Second Traction Battery?

Purchased a second traction battery and installed it in parallel with the existing battery? Perhaps one from a wrecked Prius.

I'm thinking that would double the Ev range, which would be very handy in my current commute due to long term construction on one of the highways I use. I am in sub-5 mph stop and go so long each day that I wear down my battery and the ice ends up running while stopped, thus killing my hypermiler goals.

Prius (2010-12) :: Traction Battery Cooling Fan Come On

How often should the traction battery cooling fan come on? It started to be warmer here in FL, and I hear this fan more often now. I bought my 2011 in December and up until now almost never heard this fan working. Now it comes on at least couple of times a day, mostly under heavy acceleration in Power mode.

Prius (2010-12) :: Traction Battery Gone To 1 Bar - Mileage Down?

My prius is almost 5 years old and has 88K Klm (49K Miles) My battery has gone down to one bar of late. This never happened until recently, never went below two. The bars seem to fluctuate up and down much quicker than before. My mileage is slightly down but it could be because of other reasons. Does it seem that there is something wrong with the battery? No warning lights are coming on

Prius V :: Traction Battery Gauge Never Shown Full Battery

My 2012 Prius v has a traction battery gauge beside the fuel gauge. The gauge has never shown that the battery is full. It appears as if the indicator is 2 bars below full at all times. Is this by design or should the gauge look full with bars to the very top after charging on a long trip?

Prius (2010-12) :: Traction Battery Fan Running More Than Normal?

Long time since I have posted anything here, but I noticed the fan running far more than normal here. Now the outside temp was fairly warm, but the most recent day I noticed it, the temps were only around 80-85 degrees out.

I usually don't run the AC in my car unless it is terribly hot out - so when I hear a fan running it stands out to me. It is very obvious that it is coming from the rear seat vent area.

The temps here have taken a dip (highs tomorrow are only about 70-75F), so I will keep an ear out for it to continue. Is this something to be concerned about? It is a 2010 Prius IV with about 32k miles...

GTI 337/20th Anniversary :: Dead Battery - ABS And Traction Control Light Come On

So I just drove home and the battery light comes on. A few miles later the ABS and Traction Control Light come on as well. Then I notice the windshield wipers slowing down, etc. You get the idea.

I turned everything non-essential off and made it all the way home. Of course, after I turned her off, the car won't start now.I took a couple of pictures of my battery. It always looked a bit corroded and messy, but this is pretty bad.

What I need to get the car running again? Obviously the red wire on the left is in bad shape. Is that something one can buy at the auto store? Or should I just bring her to my local shop.

Prius (2010-12) :: Engine Rattle / Knock When Traction Battery Low

So I have searched about engine rattle/knock and I have found lots of results for cold starts but I haven't found it for the issue that I am having. I have a 2010 and anytime the battery is real low, around 2 bars and the ICE fires up to charge it, any time I give it a little throttle input, I get heavy valve rattling. It doesn't matter if its cold or hot, it does it as long as the battery is low. I never get this noise when battery is charged up, only when low. I have a link to the video below and you can see once I give it some input, it starts to sound like an old diesel tractor. Prius has close to 200K on the odometer and all my maintenance is up to date. Please turn the speakers up but the noise is right at 5 seconds in or so.
