Prius (2004-09) :: Hybrid Battery Is Low Overnight
Apr 23, 2012
My hybrid battery has been running low the past few days. This has never happened before, but it has been around 90 degrees out during the same few days. I noticed it this morning as I left for work. It was down to two bars when pulling out of the garage. I was getting pretty nervous, but at least the ICE was charging it. Although, it never fully charged the system, as I live pretty close to work. On the way home, I tried to drive around for a mile or so to see if I could get the battery fully charged.. The best I could do was four bars. Is this typical of the hybrid system in warm weather? Should I be worried about it? Also, the system has a fan, why doesn't it come on if the hybrid battery is so temp sensitive?

So I got a 2008 model, only owner. It has 107K miles. I've noticed something the last couple months now. When I park the car in the garage after coming home from work it has a full charge, about 3 bars below top, it's at the max of the blue color.
When I start the car in the morning it still displays the same level. But after driving down the road about 3 blocks it seems to update slowly and drops the level, sometimes down to the brown, about 3 bars high. The car will run rough for a while almost every morning now since it's not using the hybrid battery to smooth things out.
Ever since owning the car I've noticed it can run rough sometimes normally, like when you're at a train crossing and the battery drops to 2 or 3 and the engine powers on to charge it up a bit. When I drive away you hear the engine a lot louder than usual as it seems to be running on engine only until the hybrid battery gets sufficiently charged and you feel a lack of power as you accelerate.

My concern: The hybrid battery, or the monitor really, has never, ever, not once, shown an all-bars charge. It is almost always at one bar down, and will drop below that but never goes above. My brother has a Gen I and his battery shows all bars from time to time. Not mine.

My 2006 Prius battery runs down regularly overnight. It seems to be something connected to the immobiliser and/or the interior lighting.

I see this was discussed back in 06 but not resolved. Maybe more owners have had additional experiences with this.

Should I be concerned..I have been noticing my battery is charging down overnight. I checked and all lights are off. It does charge immediately in the 10 mile I drive to work..but I am concerned why overnight it should be discharging.
Another Question - The right/left indicator sound is very muted..is that normal? Like, if I have the indicator on to merge into traffic, I am not sure it is as I can barely hear it chirping..

I recently purchased a used 2007 prius. The car has not been driven for some time. I won it in an auction from a used/wreaked car lot and am in the process of fixing it up. I need to know if it is possible to charge the hybrid battery when the car is idling or will this only discharge the hybrid battery and if so, is there any way to charge the hybrid battery other than driving the car?

i have a 2006 with almost 200k miles. Got the red triangle, check engine light, and the red car at the top of the MFD. I ran the codes and got P3000. Does this sound like traction battery failure? The car still turns on and ICE still cycles off and on.

I changed a bad cell in my hybrid battery (only one cell was bad) and put everything back together and it wont start. I've double checked all connections, fuses, everything I took off. I put the orange plug back in, fiddled with it, pushed it in more. It's got a brand new 12V battery and I dropped it off at autozone to get it charged up as well. Here are some pics and what it's showing .....

I have a 2007 Prius with 107k miles. Last July it had a minor drivers side front end collision. Last November it had the hybrid battery replaced. I believe all this is unrelated just putting it out there for information.
I am currently having the red triangle pop up intermittently. When it does a "problem" message will display on the MFD. This seems to occur most often after a long downhill or when the Energy display is showing the hybrid battery is nearly full.
The hybrid battery seems to be functioning normal and the car is driving normal and has expected fuel economy. I do have a headlight that cuts out occasionally but no other noticeable electrical problems. I do not have a diagnostic device to get the codes.

Is it normal that over night parking battery looses charge from 7 bars down to 2 bars? I never lock the car and leaving my key in it.

I just bought a certified 2010 Prius and have had it for 3 months now. Twice within one month, there was absolutely no power to start the car because the aux battery went dead overnight. I'm pretty sure I didn't leave any lights on and don't think I did anything differently when exiting the car for those 2 times. I took it into the dealership, and they couldn't find anything wrong. They said the battery was good. What is draining the battery overnight?

A year and a half ago, I had the hybrid battery warning lights come on and had it towed to the dealer. After given the option of replacing the battery for $4300, I took it home and did a single cell replacement (all cells ~8V, one at 6.6V which I replaced), which seemed to be all good until yesterday. Back with the warning lights and blower fan, I jumped to the conclusion that I have a similar situation, removed the battery and all cells are 8.04V +/- .05V except for 1 cell at 7.92. I am not convinced that this cell is really the culprit.

Just got a 2008. The Hybrid Battery Status indicator on the display is usually yellow. it will sometimes switch to blue. I assumed that yellow was the correct color but after reading some posts here it seems that they should be blue.

Can we check the health of the hybrid battery like you can the 12V. I encountered an issue where the hybrid battery had difficulty getting a "full" charge. It would frequently be in the three to two bar range which got my attention. I did learn that there is not a way to check the hybrid battery. I also have not encountered the problem since crossing the great divide on the way back ....

My 2005 prius will not start. We had some body work done to it after a deer ran into me. They did a small amount of welding and had disconnected both batteries. Now the car will not start. It can be put in auxiliary mode but if you try to start it with your foot on the brake, it flashes some lights for a few seconds and then goes dead. Is the hybrid battery too low to start the car? It was pretty low. before the batteries were disconnected. Or did they possibly do something wrong when they disconnected the hybrid battery? Final question would be do they have to do some reprogramming after disconnecting the hybrid battery?

In comparing the battery drains on a Camry hybrid versus a Prius Gen II hybrid I discovered both have three stages of battery drains after a door open incident. On a Gen II Right after the door is open the drain was 1.37 amps.

I went to drive to work today and found that my battery was drained. None of my interior lights were on and I'm 100% sure I turned the car off last night after I backed it into the garage. Last night I drove the car home and was mostly on EV, but drove the last 3-4 miles on ICE. I had the car charging overnight too. This morning, with the battery dead and the cable plugged in, it was making a click sound near the fuse box when I tried to start it.
The passenger seat's heater was on (I think) and I don't think any of the doors were ajar. The only door that could have been opened would be the driver's but I don't think it was half closed.

2005 f150 xlt supercrew. Battery dead overnight. New battery installed, and it was drained after a few days use, then an overnight sit. I hooked up my meter as required to check for an amp draw. 5.87a draw. Disconnected alternator, no change. Started pulling fuses. Fuse #107 Power Door Lock(BSM) pulled drops down to 1.04a. Radio power fuse pulled also, drops to .033a. I have had a problem with the 6 disc changer trying to load, read, eject etc so I will be changing out the head unit. I am stumped as to what to try for the 107 fuse though.

My 2007 Prius has been with me for 3 months now. I am really happy with its performance, especially its fuel consumption rate.
I would like to check the state of the hybrid battery and maintenance it if necessary. How could I get this done?

I replaced the hybrid battery in my 2005 Prius today & when I disconnected the 12v battery the wrench arced & I assume that I blew a fuse. I have looked, but have not found anything. I hope I am missing something obvious.
